Description
Verfahren zur Herstellung von Phosphorverbindungen Die Erfindung bezieht sich auf ein Verfahren zur Herstel lung von cyclischen Phosphorverbindungen.
Die erfindungsgemäss erhältlichen cyclischen Phosphor verbindungen sind biologisch aktiv und finden aufgrund ihrer biociden Wirksamkeit hauptsächlich als Insektizide und Fungizide Verwendung. Sie dienen bei der Herstellung von phosphorhaltigen Polymeren oder Copolymeren mit ande ren copolymerisierbaren Monomeren als monomere Vorstu fen. Ausserdem können sie als Kettenabbruch bewirkende Mittel sowie als Substrate in der Enzymchemie eingesetzt werden. Die durch Polymerisation der erfindungsgemässen Verbindung der Formel 1 erhältlichen polymeren Verbin dungen sind als Trennmittel (Sequestrants) brauchbar.
Es wurde nun gefunden, dass man Verbindungen der Formel 1
EMI0001.0000
worin R1, R2, R3 und R4 Wasserstoff oder aliphatische, cy- cloaliphatische, araliphatische oder aromatische Kohlenwas serstoffgruppen mit 1 bis 18 Kohlenstoffatomen, Y Chalko- gen, A eine Hydroxylgruppe, eine Gruppe -OR, wobei R einem gegebenenfalls substituierten Kohlenwasserstoffrest mit 1 bis 18 Kohlenstoffatomen entspricht, einen gegebenen falls substituierten Kohlenwasserstoffrest mit 1 bis 18 Koh lenstoffatomen oder eine Gruppe -OM und M ein Äquiva lent eines Alkali- oder Erdalkalimetalls bedeuten, dadurch gekennzeichnet, dass man eine Phosphorverbindung der Formel 2
EMI0001.0005
worin X Halogen und Keine Hydroxylgruppe be deuten,
mit einer Base der Formel 3 MYH 3 bei einer Temperatur zwischen 0 und 150 C umsetzt, wobei man je Mol Phosphorverbindung 1 bis 5 Mol Base einsetzt, und dass man anschliessend das erhaltene Reaktionsprodukt isoliert.
Bei bevorzugten Ausführungsformen bedeuten X Chlor, Y Sauerstoff und M Natrium.
Als Beispiele für die in Frage kommenden Kohlenwasser stoffgruppen R1, R2, R3 und R4 sind zu nennen: Alkylengrup pen, wie Methylen-, Äthylen-, Propylen-, Butylen-, Hexylen-, Heptylen-, Octylen-, Nonylen-, Decylen-, Undecylen-, Dodecy- len-, Hexadecylen- oder Octadecylen-Gruppen, wobei jedoch Alkylengruppen mit 1 bis 4 Kohlenstoffatomen zu bevorzu gen sind. Ausser den genannten Alkylengruppen kommen auch Cycloalkylengruppen, wie z. B.
Cycloproyplen-, Cyclo- butylen-, Cyclopentylen- oder Cyclohexylen-Gruppen sowie Arylen-, Alkarylen- und Aralkylen-Gruppen in Frage; hierzu zählen beispielsweise: Phenylen-, Diphenylen-, Naph- thylen-, Tolylen- oder Styrol-Gruppen.
Als Halogene kommen Fluor, Chor, Brom und Jod in Frage, wobei jedoch Chlor zu bevorzugen ist. Von den Chal- kogenen Sauerstoff, Schwefel, Selen und Tellur sind Sauer stoff und Schwefel, insbesondere jedoch Sauerstoff, zu be vorzugen. Von den Alkalimetallen sind Lithium, Natrium und Ka lium und von den Erdalkalimetallen Beryllium, Magnesium, Calcium, Strontium und Barium in gleicher Weise zu gebrau chen, jedoch ist Natrium aufgrund seines niedrigen Preises zu bevorzugen.
Dabei ist noch zu erwähnen, dass die Gruppe -OM in eine Gruppe A übergeführt werden kann. So kann man bei spielsweise die Gruppe -OM durch Ansäuern in eine OH-Gruppe überführen. In ähnlicher Weise ist es möglich Veresterungsprodukte herzustellen, indem man die Umset zung in einem alkoholischen Medium vornimmt oder ein nie deres Alkoxyd einwirken lässt. Weitere verschiedenartige Derivate dieser Verbindungen lassen sich durch entspre chende Auswahl der Reaktionspartner und der Reaktionsbe dingungen herstellen.
Die Gruppe R kann, falls es sich um eine aliphatische Kohlenwasserstoffgruppe handelt, ausser- dem durch Kohlenwasserstoffreste oder durch Sauerstoff oder Schwefel in Form von Äther-, Keto- oder Carboxyl- gruppen enthaltende Reste substituiert sein. Die Chalkogene enthaltenden funktionellen Gruppen sollen dabei allerdings durch wenigstens ein Kohlenstoffatom von dem Phosphor atom getrennt sein. Die Gruppe R kann ausserdem Halogene enthalten, die jedoch nur dann als inert angesehen werden können, wenn sie mindestens mit dem ss-Kohlenstoffatom verknüpft, vorteilhafterweise jedoch noch weiter entfernt vom Phosphoratom angeordnet sind.
Alkohol- und Amino- gruppen sind ungeeignet, da diese Substituenten reaktiv sind. Falls es sich bei R um eine aromatische Kohlenwasserstoff gruppe handelt, kann diese in beliebiger Stellung durch Ha logene substituiert sein.
Die Umsetzung verläuft dabei entsprechend dem nach folgend aufgeführten Reaktionsschema:
EMI0002.0006
EMI0002.0007
Die bei dieser Reaktion anfallenden cyclischen Äther werden isoliert und werden als Monomere zur Herstellung von Polymeren und Copolymeren verwendet, sind aber noch für zahlreiche andere Verwendungszwecke brauchbar.
Man verwendet zur Herstellung der cyclischen Äther Ausgangsverbindungen, bei denen X eine Hydroxylgruppe bedeutet, andernfalls wird durch die Einstellung von Reak tionsbedingungen, welche die Hydrolyse der Halogengruppe bewirken, die Bildung eines nichtcyclischen Produktes be günstigt.
Aus Gründen der Übersichtlichkeit soll das Verfahren im folgenden anhand von Verbindungen beschrieben werden, bei denen R1, R2, R3 und R4 Wasserstoff, M Natrium und Y Sauerstoff bedeuten und Chlor für Halogen steht.
Das Verfahren kann in der Weise durchgeführt werden, dass man ein Reaktionsgefäss mit einer geeigneten basi schen Verbindung und mit Bis-(chlormethy)-phosphinsäure beschickt.
Wenn Y Sauerstoff bedeutet, wie im vorliegenden Fall, können Alkali- oder Erdalkalihydroxyde als basische Verbin dungen eingesetzt werden. Bedeutet Y hingegen Schwefel, so müssen die entsprechenden Sulfide eingesetzt werden. Das gleiche gilt für Selen und Tellur, wobei die entsprechen den Selenide bzw. Telluride zur Anwendung gelangen. Ob gleich Ammonium im allgemeinen als den Alkalimetallen gleichwertig angesehen werden kann., ist es im vorliegenden Fall ungeeignet und scheidet aus.
Die Menge der zur Anwendung kommenden basischen Verbindung, z. B. NaOH, richtet sich nach dem verwendeten Ausgangsmaterial sowie nach den gewünschten Endproduk ten. Wird z. B. als Ausgangsmaterial Hydroxymethyl- (chlor methyl>phosphinsäure verwendet, so benötigt man zur Her stellung des cyclischen Äthers 2 bis 2,2 Mol Natriumhydro xyd. Verwendet man mehr als 3 Mol Natriumhydroxyd je Mol Hydroxymethyl-(chlormethyl)-phosphinsäure, so erhält man das saure Salz der Methoxymethylphosphonsäure. Die Gesamtmenge an benötigter Base hängt davon ab, ob das Ausgangsmaterial eine Säure ist oder nicht. Ist das Aus gangsmaterial eine Säure, so muss die Menge der zugegebe nen Base so gewählt werden, dass die Säure neutralisiert wird, bevor die Umsetzung stattfinden kann.
In ähnlicher Weise muss, wenn eine Bis-chlormethyl- oder eine Bis-chlor- alkyl-verbindung verwendet wird, die Base in einer Menge zugegeben werden, die ausreicht, um eines der Chloratome zu entfernen, damit die Monochlormonohydroxy-verbindung erhalten wird.
Nach Zugabe der basischen Verbindung erhitzt man das Reaktionsgemisch auf eine Temperatur von 0 bis 150 C, vorzugsweise von 20 C bis 100 C.
Durch Anwendung inerter Lösungsmittel kann die Um setzung wirksam beeinflusst werden. Als besonders geeignet haben sich polare Lösungsmittel wie Wasser und Alkohole erwiesen, wobei Wasser aus naheliegenden Gründen als Reaktionsmedium bevorzugt wird. Als Beispiele für geeig nete Lösungsmittel sind neben Wasser Alkohole mit 1 bis 12 Kohlenstoffatomen, Diäthyläther, Dioxan, Tetrahydrofuran, Acetonitril und dergleichen zu nennen.
Ausserdem kann die Umsetzung bei Unter- oder Über druck durchgeführt werden; die Durchführung bei Normal druck wird jedoch bevorzugt.
Die Bildung des cyclischen Äthers kann beispielsweise folgendermassen vor sich gehen. Man behandelt eine Ver bindung der Formel
EMI0003.0000
mit einem Äquivalent wässriger Natriumhydroxydlösung bei einer Temperatur zwischen 60 C und 80 C. Dabei entsteht eine Verbindung der Formel
EMI0003.0001
Man kühlt die Lösung auf eine Temperatur von 10 C ab und säuert mit ungefähr einem Äquivalent verdünnter Salz säure (5- bis 10%ig) an. Man erhält so den cyclischen Äther in Form der freien Säure. Diesem kommt die folgende For mel zu
EMI0003.0002
Das Lösungsmittel wird durch Verdampfen unter ver mindertem Druck bei 10 bis 20 mm Hg und einer Tempera tur von 20 C bis 40 C entfernt. Anschliessend wird bei 20 C getrocknet. Das gewonnene Produkt wird bei einer Temperatur von 10 C bis 15 C in Aceton gelöst.
Das erhal tene Gemisch wird filtriert und das bei der Umsetzung ge bildete Natriumchlorid als unlöslicher Niederschlag abge trennt. Das Filtrat wird erneut unter vermindertem Druck bei 10 bis 20 mm Hg und einer Temperatur von 10 C bis 15 C eingedampft. Nach Entfernung des gesamten Lösungs mittels erhält man als Reaktionsprodukt den cyclischen Äther. Dieser muss bei einer Temperatur zwischen -20 C und 0 C aufbewahrt werden, da er sonst mit sich selbst rea giert. Das Produkt ist eine farblose Flüssigkeit.
Wie bereits früher erwähnt, lässt sich der cyclische Äther zu einer polymeren Verbindung polymerisieren. Aus- serdem ist es möglich Copolymere mit Verbindungen wie Äthylenoxyd, Propylenoxyd, 1,3-Propylenoxyd oder anderen copolymerisierbaren Verbindungen herzustellen.
Die Homopolymerisation verläuft entsprechend dem nachfolgend wiedergegebenen Schema. Reaktionsschema II
EMI0003.0007
n bedeutet darin die Anzahl der wiederkehrenden Einheiten. Die Polymerisation verläuft autokatalytisch; die Zugabe an derer Katalysatoren oder Katalysatorsysteme ist nicht erfor derlich. Lediglich in den Fällen in denen hochmolekulare Po lymere erwünscht sind, ist es zweckmässig einen Katalysator vom Friedel-Crafts-Typ, z. B. Aluminiumchlorid, Zinn-IV-chlo- rid, Eisen-III-chlorid, Bortrifluorid, Antimonpentafluorid oder Phosphorpentafluorid, zuzusetzen.
Obgleich bei dem im oben stehenden Reaktionsschema gegebenen Beispiel der cyclische Äther in seiner Säureform zum Einsatz gelangt, muss erwähnt werden, dass es in bezug auf die zu erhaltenden polymeren Produkte vorteilhafter ist, den cyclischen Äther nicht in Form der freien Säure einzu setzen. Besonders günstige Ergebnisse werden erzielt, wenn man Verbindungen verwendet, bei denen die an Phosphor gebundene Hydroxylgruppe durch die Gruppe -0R bzw. -R, wobei R einem Kohlenwasserstoffrest entspricht, ersetzt ist. Die Anzahl der wiederkehrenden Einheiten beträgt in der Regel 5 bis 100. Es können jedoch höher molekulare Poly mere durch Einstellung entsprechender optimaler Bedingun gen erhalten werden.
Falls die erfindungsgemäss erhältlichen Verbindungen als polymere Produkte oder als monomere Zusätze verwendet werden sollen, um die Flammbeständigkeit anderer polyme rer Produkte zu erhöhen, so ist es vorteilhaft, Antimonsalze, welche als flammfestmachende Zusätze bekannt sind, zuzu geben und eine Salzbildung mit dem Phosphorsäurerest herbeizuführen. Die auf diese Weise erhaltenen Produkte zeichnen sich durch eine erhöhte Flammfestigkeit aus.
Die nachfolgenden Beispiele dienen zur Erläuterung der Erfindungen. Bei den Mengen und Prozentangaben handelt es sich, soweit nicht anders erwähnt, um Gewichtseinheiten. Beispiel 1 Cyclisches Produkt und Polymeres Eine Lösung von 28,8 g
EMI0003.0011
in 500 ml Wasser wird durch Zugabe von 200 ml ln-Natri- umhydroxyd basisch gemacht. Das Reaktionsprodukt wird auf ungefähr 95 C bis 100 C erhitzt, und weitere 200 ml ln-Natriumhydroxyd werden langsam während 5'6 Stunden zugegeben. Die Lösung wird im Vakuum eingedampft.

EMI0004.0003
chlorid (vom obigen Beispiel) (0,155 Mol, bezogen auf die P-Analyse) in 150 ml Wasser bei ungefähr 1 C bis 2 C wird mit 39 ml einer 4n-Salzsäure behandelt. Die Lösung wird bei einem Druck von 10 bis 20 mm Hg bei einer Temperatur von 20 C bis 40 C eingedampft. Dann fügt man 200 ml kal tes Aceton zu. Die Mischung wird zwecks Entfernung des Natriumchlorids filtriert. Das Filtrat wird unter Vakuum bei einer Temperatur von ungefähr 10 C bis 15 C eingedampft und liefert 18 g eines flüssigen Produkts.
Das Rohprodukt titriert als eine einbasische Säure mit einem Molekulargewicht von 126. Theoretisches Molekular gewicht ist 126. Nach Trocknen über P205 bei 25 C erhält man eine Ausbeute von 16,7 g. Die theoretische Ausbeute beträgt 16,75 g. Nach dem Trocknen ist das Neutralisations äquivalent 226. Beim Trocknen bei einer Temperatur von 100 C bei 1 mm Hg Druck ergibt sich kein Gewichtsverlust. Gefunden wird ein Neutralisationsäquivalent von 306. Nach weiterem Erhitzen polymerisiert das Produkt zu einem dik- ken Sirup, der durch das Kernresonanzspektrum bestätigt wird.
Beispiel 2
EMI0004.0007
100 g Wasser, 8,6 g Natriumhydroxyd (0,215 Mol) und 17,2 g Natriumsulfid (0,22 Mol) wird langsam in ungefähr einer Stunde auf eine Temperatur von ungefähr 60 C erhitzt. Die Lösung wird darauf ungefähr 2 Stunden lang auf Rückfluss- temperatur (100 C bis 102 C) erhitzt. Dann werden 19,5 ml 36%ige Salzsäure (0,23 Mol) zugesetzt und die Lösung zur Entfernung des Lösungsmittels eingedampft. Dann gibt man 100 ml 37%ige Salzsäure zu und filtriert das Gemisch, um un lösliches Natriumchlorid zu entfernen. Bleiacetat wird zuge setzt, damit sich etwa vorhandene zweibasische Säuren als Verunreinigungen absetzen, welche durch Filtrieren entfernt werden.

Process for the production of phosphorus compounds The invention relates to a process for the production of cyclic phosphorus compounds.
The cyclic phosphorus compounds obtainable according to the invention are biologically active and, because of their biocidal activity, are mainly used as insecticides and fungicides. They are used as monomeric precursors in the production of phosphorus-containing polymers or copolymers with other copolymerizable monomers. In addition, they can be used as chain terminators and as substrates in enzyme chemistry. The polymeric compounds obtainable by polymerization of the compound of formula 1 according to the invention can be used as release agents (sequestrants).
It has now been found that compounds of the formula 1
EMI0001.0000
wherein R1, R2, R3 and R4 are hydrogen or aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon groups with 1 to 18 carbon atoms, Y chalcogen, A a hydroxyl group, a group -OR, where R is an optionally substituted hydrocarbon radical with 1 to 18 carbon atoms, an optionally substituted hydrocarbon radical with 1 to 18 carbon atoms or a group -OM and M is an equivalent of an alkali or alkaline earth metal, characterized in that a phosphorus compound of the formula 2
EMI0001.0005
where X signifies halogen and no hydroxyl group,
with a base of the formula 3 MYH 3 is reacted at a temperature between 0 and 150 ° C., 1 to 5 moles of base being used per mole of phosphorus compound, and the reaction product obtained is then isolated.
In preferred embodiments, X is chlorine, Y is oxygen and M is sodium.
Examples of the hydrocarbon groups R1, R2, R3 and R4 in question include: alkylene groups, such as methylene, ethylene, propylene, butylene, hexylene, heptylene, octylene, nonylene, decylene , Undecylene, dodecylene, hexadecylene or octadecylene groups, although alkylene groups with 1 to 4 carbon atoms are preferred. In addition to the alkylene groups mentioned, there are also cycloalkylene groups, such as. B.
Cycloproyplene, cyclobutylene, cyclopentylene or cyclohexylene groups and arylene, alkarylene and aralkylene groups are possible; these include, for example: phenylene, diphenylene, naphthylene, tolylene or styrene groups.
Fluorine, chlorine, bromine and iodine can be used as halogens, but chlorine is preferred. Of the chalcogens oxygen, sulfur, selenium and tellurium, preference is given to oxygen and sulfur, but in particular oxygen. Of the alkali metals, lithium, sodium and potassium and of the alkaline earth metals beryllium, magnesium, calcium, strontium and barium can be used in the same way, but sodium is preferable because of its low price.
It should also be mentioned that the group -OM can be converted into a group A. For example, the -OM group can be converted into an OH group by acidification. In a similar way, it is possible to produce esterification products by carrying out the reaction in an alcoholic medium or by letting a lower alkoxide act. Other different types of derivatives of these compounds can be prepared by appropriate selection of the reactants and the reaction conditions.
If it is an aliphatic hydrocarbon group, the group R can also be substituted by hydrocarbon radicals or by oxygen or sulfur in the form of radicals containing ether, keto or carboxyl groups. The functional groups containing chalcogens should, however, be separated from the phosphorus atom by at least one carbon atom. The group R can also contain halogens which, however, can only be regarded as inert if they are linked at least to the β-carbon atom, but are advantageously arranged further away from the phosphorus atom.
Alcohol and amino groups are unsuitable because these substituents are reactive. If R is an aromatic hydrocarbon group, it can be substituted in any position by halogenes.
The reaction proceeds according to the reaction scheme listed below:
EMI0002.0006
EMI0002.0007
The cyclic ethers obtained in this reaction are isolated and used as monomers for the production of polymers and copolymers, but can also be used for numerous other purposes.
For the preparation of the cyclic ethers, starting compounds are used in which X is a hydroxyl group, otherwise the formation of a non-cyclic product is favored by setting reaction conditions which cause the hydrolysis of the halogen group.
For the sake of clarity, the process will be described below on the basis of compounds in which R1, R2, R3 and R4 are hydrogen, M is sodium and Y is oxygen and chlorine is halogen.
The process can be carried out in such a way that a reaction vessel is charged with a suitable basic compound and with bis (chloromethyl) phosphinic acid.
If Y is oxygen, as in the present case, alkali or alkaline earth metal hydroxides can be used as basic compounds. If, on the other hand, Y is sulfur, the corresponding sulfides must be used. The same applies to selenium and tellurium, the corresponding selenides and tellurides being used. Although ammonium can generally be regarded as equivalent to the alkali metals, it is unsuitable in the present case and is ruled out.
The amount of the basic compound used, e.g. B. NaOH, depends on the starting material used and on the desired Endproduk th. If, for example, hydroxymethyl (chloromethyl> phosphinic acid is used as the starting material), 2 to 2.2 moles of sodium hydroxide are required to produce the cyclic ether the acid salt of methoxymethylphosphonic acid. The total amount of base required depends on whether the starting material is an acid or not. If the starting material is an acid, the amount of base added must be chosen so that the acid is neutralized, before implementation can take place.
Similarly, if a bis-chloromethyl or a bis-chloro-alkyl compound is used, the base must be added in an amount sufficient to remove one of the chlorine atoms in order for the monochloromonohydroxy compound to be obtained.
After the basic compound has been added, the reaction mixture is heated to a temperature from 0 to 150 ° C., preferably from 20 ° C. to 100 ° C.
The implementation can be effectively influenced by using inert solvents. Polar solvents such as water and alcohols have proven to be particularly suitable, with water being preferred as the reaction medium for obvious reasons. Examples of suitable solvents are water, alcohols having 1 to 12 carbon atoms, diethyl ether, dioxane, tetrahydrofuran, acetonitrile and the like.
In addition, the reaction can be carried out under negative or positive pressure; however, it is preferred to carry out this at normal pressure.
The formation of the cyclic ether can proceed as follows, for example. One deals with a compound of the formula
EMI0003.0000
with one equivalent of aqueous sodium hydroxide solution at a temperature between 60 C and 80 C. A compound of the formula is formed
EMI0003.0001
The solution is cooled to a temperature of 10 C and acidified with approximately one equivalent of dilute hydrochloric acid (5-10%). The cyclic ether is thus obtained in the form of the free acid. The following formula applies to this
EMI0003.0002
The solvent is removed by evaporation under reduced pressure at 10 to 20 mm Hg and a tempera ture of 20 C to 40 C. It is then dried at 20.degree. The product obtained is dissolved in acetone at a temperature of 10 C to 15 C.
The mixture obtained is filtered and the sodium chloride formed during the reaction is separated off as an insoluble precipitate. The filtrate is again evaporated under reduced pressure at 10 to 20 mm Hg and a temperature of 10 to 15 C. After removing all of the solvent, the cyclic ether is obtained as the reaction product. This must be kept at a temperature between -20 C and 0 C, otherwise it will react with itself. The product is a colorless liquid.
As mentioned earlier, the cyclic ether can be polymerized to a polymeric compound. It is also possible to produce copolymers with compounds such as ethylene oxide, propylene oxide, 1,3-propylene oxide or other copolymerizable compounds.
The homopolymerization proceeds according to the scheme shown below. Reaction scheme II
EMI0003.0007
n means the number of recurring units. The polymerization proceeds autocatalytically; the addition of other catalysts or catalyst systems is not required. Only in those cases in which high molecular weight Po polymers are desired, it is appropriate a catalyst of the Friedel-Crafts type, for. B. aluminum chloride, tin-IV-chloride, iron-III-chloride, boron trifluoride, antimony pentafluoride or phosphorus pentafluoride to be added.
Although the cyclic ether in its acid form is used in the example given in the reaction scheme above, it must be mentioned that, with regard to the polymeric products to be obtained, it is more advantageous not to use the cyclic ether in the form of the free acid. Particularly favorable results are achieved if compounds are used in which the hydroxyl group bonded to phosphorus has been replaced by the group -OR or -R, where R corresponds to a hydrocarbon radical. The number of recurring units is usually 5 to 100. However, higher molecular weight polymers can be obtained by setting appropriate optimal conditions.
If the compounds obtainable according to the invention are to be used as polymeric products or as monomeric additives in order to increase the flame resistance of other polymeric products, it is advantageous to add antimony salts, which are known as flame-retardant additives, and to bring about salt formation with the phosphoric acid residue. The products obtained in this way are distinguished by increased flame resistance.
The following examples serve to illustrate the inventions. Unless otherwise stated, the quantities and percentages are units of weight. Example 1 Cyclic Product and Polymer A solution of 28.8 g

chloride (from the above example) (0.155 mol, based on the P analysis) in 150 ml of water at about 1 C to 2 C is treated with 39 ml of 4N hydrochloric acid. The solution is evaporated at a pressure of 10 to 20 mm Hg at a temperature of 20 ° C to 40 ° C. 200 ml of cold acetone are then added. The mixture is filtered to remove the sodium chloride. The filtrate is evaporated under vacuum at a temperature of approximately 10 ° C to 15 ° C to give 18 g of a liquid product.
The crude product is titrated as a monobasic acid with a molecular weight of 126. Theoretical molecular weight is 126. After drying over P205 at 25 ° C., a yield of 16.7 g is obtained. The theoretical yield is 16.75 g. After drying, the neutralization is equivalent to 226. There is no weight loss on drying at a temperature of 100 ° C. and a pressure of 1 mm Hg. A neutralization equivalent of 306 is found. After further heating, the product polymerizes to a thick syrup, which is confirmed by the nuclear magnetic resonance spectrum.

100 g of water, 8.6 g of sodium hydroxide (0.215 mol) and 17.2 g of sodium sulfide (0.22 mol) are slowly heated to a temperature of about 60 ° C. in about one hour. The solution is then heated to reflux temperature (100 ° C to 102 ° C) for about 2 hours. 19.5 ml of 36% strength hydrochloric acid (0.23 mol) are then added and the solution is evaporated to remove the solvent. 100 ml of 37% strength hydrochloric acid are then added and the mixture is filtered in order to remove insoluble sodium chloride. Lead acetate is added so that any dibasic acids present settle as impurities, which are removed by filtration.
The filtrate is evaporated to give a solid colorless product in a yield of approximately 21 g. Analysis: Found: 24.1% P; 22.2% S.
