Description
Die Erfindung betrifft neue Zusammensetzungen, die als Funktionsfließmittel
bzw. Funktionsflüssigkeiten brauchbar sind, Zusammensetzungen, die Additive enthalten und Dichtungen in
Betriebsanlagen und Maschinen quellen und die Bildung von Wasser-in-Öl-Emulsionen
hemmen,sowie Verfahren zur Bewirkung einer Quellung dieser Dichtungen.
Spezieller betrifft die Erfindung nach einem ihrer Aspekte Zusammensetzungen,
die eine ölartige Flüssigkeit mit Schmierviskosität und ein polyfunktionelles Nitril der allgemeinen Formel

umfassen, worin X O, S oder NR bedeutet, R einen einwertigen
oder mehrwertigen Kohlenwasserstoffrest mit etwa 4 bis 25 Kohlenstoffatomen,
vorzugsweise einen einwertigen oder mehrwertigen gesättigten aliphatischen Rest mit etwa 4 bis 25 Kohlen-

R ein Wasserstoffatom oder eine niedermolekulare Alkylgruppe,
m die Wertigkeit von R und η eine ganze Zahl von 0 bis 2 bedeutet.
Nach einem anderen Aspekt betrifft die Erfindung ein Verfahren zum Quellen von Dichtungen in Betriebsanlagen oder Maschinen,
das darin besteht, daß man diese Dichtungen mit einem polyfunktionellen
Nitril der allgemeinen Formel
R6/X-fCH\ CHCN? (II)
in Berührung bringt, worin R einen mehrwertigen Kohlenwasserstoff rest mit etwa 4 bis 25 Kohlenstoffatomen bedeutet, ρ die
Wertigkeit von R bedeutet und X, R, R, R, R und η wie oben definiert sind.
Das Problem einer Schrumpfung von Dichtungen, besonders von elastomeren Dichtungen, in Betriebsanlagen oder Maschinen (wie
709825/0876
.6·
beispielsweise automatischen Übertragungen für Motorfahrzeuge)
bei Berührung mit Funktionsfließmitteln ist von großer Bedeutung, da eine solche Schrumpfung Leckstellen für das Funktionsfließmittel
verursacht, die zu einem fehlerhaften Betrieb der Maschinerie oder zu einem völligen Versagen derselben führen
können (der Ausdruck "Funktionsfließmittel", wie er hier verwendet
wird, bedeutet ein Fließmittel bzw. eine Flüssigkeit, die etwas mit der übertragung von Energie zu tun hat oder diese
erleichtert, wie ein Schmiermittel, eine hydraulische Flüssigkeit, ein automatisches Übertragungsfließmittel, ein Wärmeaustauschmedium
oder dergleichen). Um dieses Problem zu beseitigen, ist es üblich, dem Funktionsfließmittel ein Additiv bzw. einen
Zusatzstoff zuzusetzen, dessen Vorhandensein darin die Dichtung zum Quellen bringt. Eine Reihe solcher Additive ist
in der Technik bekannt, doch hat ihre Verwendung verschiedene Nachteile. Beispielsweise haben viele von ihnen physiologisch
nachteilige Wirkungen. Außerdem müssen sie oftmals in unerwünscht großen Mengen in dem Funktionsfließmittel verwendet
werden.
Ein zweites Problem, das manchmal auftritt, besonders bei Getriebeschmiermitteln,
ist die Bildung von Wasser-in-Öl-Emulsionen. Eine solche Emulsionsbildung, die die Wirksamkeit des
Schmiermittels beeinträchtigt, wird oftmals durch darin vorhandene Additive verschlimmert. Obwohl es manchmal möglich sein
mag, diese Additive zu ersetzen, ist es auch erwünscht, geeignete Demulgatoren für die Verwendung mit ihnen zu entwickeln.
Ein Hauptziel der vorliegenden Erfindung ist es daher, neue Zusammensetzungen zu bekommen, die in der Lage sind, in Betriebs-
709825/0876
anlagen oder Maschinen verwendete Dichtungen quellen zu lassen oder deren Schrumpfung auf ein Minimum zu bringen. Ein weiteres
Ziel ist es, dichtungsquellende Schmiermittel und Funktionsflüssigkeiten zu bekommen, die Additive enthalten, welche relativ
weniger.nachteilige physiologische Wirkungen haben als die
derzeit in Gebrauch befindlichen Additive.
Ein weiteres Ziel ist, Schmiermittel und Funktionsflüssigkeiten
zu bekommen, die extrem kleine, aber wirksame Mengen an dichtungsquellenden
Additiven enthalten.
Noch ein anderes Ziel besteht darin, ein neues Verfahren zum
Quellen oder Kleinhalten der Schrumpfung von Dichtungen unter Verwendung relativ kleiner Mengen relativ harmloser und ungiftiger
Additive zu bekommen. Noch ein anderes Ziel besteht darin, verbesserte Schmiermittel, besonders Getriebeschmiermittel
zu bekommen, die der Bildung von Wasser-in-Öl-Emulsionen widerstehen.
.
Wie oben festgestellt wurde, umfassen die Zusammensetzungen nach der Erfindung zwei Komponenten, von denen die erste eine
Ölartige Flüssigkeit mit Schmierviskosität ist. Solche Flüssigkeiten sind beispielsweise natürliche und synthetische Öle und
Gemische derselben, besonders öle von dem Typ, der als Kurbelgehäuseschmieröle
für funkengezündete und kompressionsgezündete Verbrennungsmaschinen, wie Automobil- und Lastwagenmotoren,
Zweitaktmotoren, Luftfahrtkolbenmotoren, Schiffs- und Eisenbahndieselmotoren sowie Gasmotoren, stationäre Kraftmaschinen
und Turbinen und dergleichen brauchbar ist. Grundflüssigkeiten für automatische Obertragungsfließmittel, Achsenschmiermittel
, Getriebeschmiermittel, Metallverarbeitungsschmiermit-

' " 2654A 12
•f·
tel, hydraulische Flüssigkeiten und andere Schmieröle und
Schmierfette sind auch für diesen Zweck brauchbar.
Natürliche Öle sind beispielsweise tierische öle und pflanzliche Öle (wie Rizinusöl, Schmalzöl) sowie flüssige Mineralöle
und mit Lösungsmittel behandelte oder mit Säure behandelte Schmiermineralöle vom Paraffintyp, Naphthentyp oder gemischten
Paraffin-Naphthentyp. Solche Mineralöle sind bevorzugt. Öle mit Schmierviskosität, die sich nicht nur von Erdöl, sondern
auch von Kohle oder Schiefer herleiten, sind ebenfalls brauchbar.
Synthetische Schmieröle sind beispielsweise Kohlenwasserstofföle und halogensubstituierte Kohlenwasserstofföle, wie polymerisierte
und interpolymerisierte Olefine /ζ.B. Polybutylene,
Polypropylene, Propylen-Isobutylenmischpolymere, chlorierte Polybutylene, Poly-(1-hexene), Poly-(1-octene), Poly-(1-decene)
usw. sowie Gemische derselben/r Alkylbenzole ,/z.B. Dodecylbenzole,
Tetradecy!benzole, Dinonylbenzole, Di-(2-äthylhexyl)-benzole
USW1/, Polyphenyle (z.B. Biphenyle, Terphenyle, alkylierte
Polyphenyle usw.), alkylierte Diphenylather und alkylierte
Diphenylsulfide und deren Derivate, Analoge und Homologe und dergleichen.
Alkylenoxidpolymere und -interpolymere und Derviate derselben,
worin die endständigen Hydroxylgruppen durch Veresterung, Verätherung usw. modifiziert wurden, stellen eine andere Klasse
bekannter synthetischer Öle dar. Beispiele hierfür sind die Öle, die durch Polymerisation von Äthylenoxid oder Propylenoxid hergestellt
werden, die Alkyl- und Aryläther dieser Polyalkylenpolymere (wie Methylpolyisopropylenglycoläther mit einem mitt-
709825/0876
•J.
leren Molekulargewicht von 1000, Diphenylather von Polyäthylenglycol
mit einem Molekulargewicht von 500 bis 1000, Diäthyläther von Polypropylenglycol mit einem Molekulargewicht von
1000 bis 1500 usw.) oder deren Mono- oder Polycarbonsäureester,
wie beispielsweise die Essigsäureester, gemischte C -Cg-Fettsäureester
oder die C.--Oxosäurediester von Tetraäthylenglycol.
Eine andere geeignete Klasse synthetischer öle umfaßt die Ester für Dicarbonsäuren (z.B. von Phthalsäure, Bernsteinsäure, Alkylbernsteinsäuren
und Alkenylbernsteinsäuren, Maleinsäure, Azelainsäure, Suberinsäure, Sebacinsäure, Fumarsäure, Adipinsäure,
Linolsäuredimer, Malonsäure, Alkylmalonsäuren, Alkenylmalonsäuren usw.) mit einer Vielzahl von Alkoholen (wie Butylalkohol,
Hexylalkohol, Dodecylalkohol, 2-Äthylhexylalkohol,
Äthylenglycol, Diäthylenglycolmonoäther, Propylenglycol usw.).
Spezielle Beispiele dieser Ester sind etwa Dibutyladipat, Di-(2-äthylhexyl)-sebacat, Di-n-hexylfumarat, Dioctylsebacat,
Diisooctylazelat, Diisodecylazelat, Dioctylphthalat,Didecylphthalat,
Dieicosylsebacat, der 2-Äthylhexyldiester von Linolsäuredimer,
der komplexe Ester, der sich bei Umsetzung von 1 Mol Sebacinsäure mit 2 Mol Tetraäthylenglycol und 2 Mol 2-Äthylhexansäure
bildet, und dergleichen.
Als synthetische öle brauchbare Ester sind auch jene aus C5-C _-
Monocarbonsäuren und Polyolen und Polyoläthern, wie Neopentylglycol,
Trimethylolpropan, Pentaerythrit, Dipentaerythrit, Tripentaerythrit
usw.
Öle auf Siliciumbasis, wie Polyalkyl-, Polyaryl-, Polyalkoxy-.oder
Polyaryloxysiloxanöle und -silicatöle umfassen eine andere brauchbar Klasse synthetischer öle ,/z.B. Tetraäthylsilicat,

Tetraisopropylsilicat, Tetra-(2-äthylhexyl)-silicat, Tetra-(4-methyl-2-äthylhexyl)-silicat,
Tetra-(p-tertiärbuty!phenyl)-silicat, Hexyl-(4-methyl-2-pentoxy)-disiloxan, Poly-(methyl)-siloxane,
Poly-(methy!phenyl)-siloxane usw^J. Andere synthetische
öle sind beispielsweise flüssige Ester von phosphorhaltigen Säuren (wie Tricresy!phosphat, Triocty!phosphat, Diäthylester
von Decylphosphonsäure usw.), polymere Tetrahydrofurane
und dergleichen.
Unraffinierte, raffinierte und wieder raffinierte Öle (und Gemische
jedes derselben miteinander) des oben beschriebenen Typs können bei der vorliegenden Erfindung verwendet werden. Unraffinierte
öle sind jene, die man direkt aus einer natürlichen oder synthetischen Quelle ohne weitere Reinigungsbehandlung
erhält. Beispielsweise wäre ein unraffiniertes Öl ein Schieferöl,
das man direkt durch Retortenbehandlung erhalten hat, ein aus Erdöl gewonnenes öl, das man direkt durch Destillation gewonnen
hat, oder ein Esteröl, das man direkt aus einem Veresterungsverfahren gewonnen hat, wobei diese Öle ohne weitere
Behandlung verwendet werden. Raffinierte öle sind ähnlich den unraffinierten, jedoch mit der Ausnahme, daß sie in einer oder
mehreren Reinigungsstufen weiter behandelt wurden, um eine oder mehrere Eigenschaften derselben zu verbessern. Dem Fachmann
sind viele solcher Reinigungstechniken bekannt, wie Lösungsmittelextraktion, Säure- oder Basenextraktion, Filtration,
Percolation usw. Wieder raffinierte Öle erhält man durch Verfahren,
die ähnlich jenen sind, welche benutzt werden, um raffinierte Öle zu erhalten, doch werden diese Verfahren dann dazu
angewendet, raffinierte Öle aus solchen Ölen zu erhalten, die bereits benutzt wurden. Solche raffinierten Öle sind auch
709825/0876
als wieder benutzte oder wieder verarbeitete öle bekannt und werden oftmals zusätzlich durch Methoden behandelt, die darauf
gerichtet sind, verbrauchte Additive und ölabbauprodukte zu
entfernen.
Die dichtungsquellende Komponente in den Zusammensetzungen nach der Erfindung ist ein polyfunktionelles Nitril mit der obigen
Formel I (der Kürze halber soll in der gesamten Beschreibung die Singularform auch den Plural einschließen, es sei denn, daß
der Begleittext die Bedeutung der Singularform erfordert. So schließt beispielsweise Begriff "ein polyfunktionelles Nitril"
auch ein Gemisch zweier oder mehrerer solcher Nitrile ein). In diesen polyfunktioneIlen Nitrilen ist X ein Sauerstoffatom
(was bevorzugt ist), ein Schwefelatom oder ein Stickstoffatom, je nachdenijOb das Nitril (wie oben beschrieben) aus einem Alkohol,
einem Mercaptan oder einem Amin hergestellt wird. Wenn
X ein Stickstoffatom bedeutet, enthält es einen R -Substituenten,
der ein Wasserstoffatom (wenn das Ausgangsmaterial ein
primäres Amin ist), ein Kohlenwasserstoffrest (wenn das Ausgangsmaterial ein sekundäres Amin ist) oder der Rest

(wie beispielsweise ein mit 2 Mol eines ungesättigten Nitrils umgesetztes primäres Amin) sein kann.
Wenn hier der Ausdruck "Kohlenwasserstoffrest" benutzt wird,
bedeutet dieser einen Rest mit einem direkt an den übrigen Teil des Moleküls gebundenen Kohlenstoffatom und mit vorherrschend
KohlenwasserstoffCharakter, und zwar im gesamten Begleittext dieser Erfindung. Solche Kohlenwasserstoffrest sind beispielsdie
folgenden:

Phenyl, Tolyl, Heptylphenyl, Isopropenylphenyl und Naphthyl
(wobei alle Isomere solcher Reste eingeschlossen sind, wenn mehr als ein Isomeres möglich ist).
2. Substituierte Kohlenwasserstoffreste, d.h. Reste mit Nichtkohlenwasserstoff
substituenten, die im Zusammenhang mit dieser Erfindung den vorherrschenden KohlenwasserstoffCharakter des
Restes nicht ändern. Dem Fachmann sind geeignete Substituenten bekannt. Beispiele hierfür sind Halogen (Fluor, Chlor, Brom,
Jod), Nitro, Cyano,

Vorzugsweise sind die Kohlenwasserstoffreste, die als R in den Verbindungen der Formel I vorhanden sind, frei von acetylenischer und gewöhnlich auch von äthylenischer Ungesättigtheit,
und sie haben etwa 1 bis 30 Kohlenstoffatome, erwünschtermaßen etwa 1 bis 10 Kohlenstoffatome. Die Reste sind gewöhnlich Kohlenwasserstoffreste und spezieller niedermolekulare Kohlenwasserstoffreste, wobei das Wort "niedermolekulare" Reste mit bis zu 7 Kohlenstoffatomen bedeutet. Sie sind vorzugsweise niedermolekulare Alkyl- oder Arylreste, besonders niedermolekulare

R und R sind wie oben definiert. Beide sind gewöhnlich Wasserstoffatome
oder niedermolekulare Alkylgruppen (besonders Methyl), und bevorzugt Wasserstoffatome.
Die ganze Zahl m ist gleich der Wertigkeit des Restes R . So
ist diese Zahl gewöhnlich 1 oder 2 und vorzugsweise 1. Die ganze Zahl η ist 0,1 oder 2 und vorzugsweise 1.
Wie oben bereits gesagt wurde, ist ein anderer Aspekt dieser Erfindung ein Verfahren zur Quellung von Dichtungen durch Berührung
derselben mit einem polyfunktionellen Nitril der Formel II, wobei dieses polyfunktionelle Nitril gewöhnlich in der
oben erwähnten ölartigen Flüssigkeit mit Schmierviskosität gelöst ist. Der Rest R in der Formel II ist ein einwertiger
oder mehrwertiger Kohlenwasserstoffrest entsprechend der obigen weiteren Definition. Das heißt, er kann mit R in der Formel
I identisch sein und ist es gewöhnlich auch, und er kann auch ein aromatischer Rest (wie Phenyl, Naphthyl, Phenylen)
oder ein heterozyklischer Rest (wie Pyridyl, Piperidyl, Furyl,
Thienyl, Morpholinyl, Indolyl) sein. Wie es der Fall bei dem Rest R ist, ist der Rest R gewöhnlich einwertig (vorzugsweise)
oder zweiwertig. Das heißt, ρ ist 1 (vorzugsweise) oder 2.
Beispiele polyfunktioneller Nitrile der Formel II, die in dem
Verfahren nach der Erfindung verwendet werden können, finden sich in der nachfolgenden Tabelle I und sind als Verbindungen A
bis L bezeichnet.

Die Verbindungen der Formeln I und II, worin η 1 ist, sind
bekannt und können durch Cyanoäthylierung oder dergleichen von Alkoholen, Phenolen, Mercaptanen oder Aminen hergestellt
werden, d.h. durch umsetzung solcher Verbindungen mit Acrylnitril oder mit analogen Nitrilen, wie Methacrylnitril,
cJ-Chloracrylnitril, Crotonnitril oder Äthyl-2-cyanoacrylat.
Die Cyanoäthylierung solcher Verbindungen ist in Bruson, Organic Reactions, 5, 79 (1949) beschrieben, worauf hier Bezug genommen
wird.
Verbindungen, in denen η O ist, können durch-die Umsetzung
von Cyanhydrinen mit Alkoholen, Phenolen, Mercaptanen oder Aminen hergestellt werden. Jene, in welchen η 2 ist, können
durch die Umsetzung eines Butyrolactons mit einem Alkohol, Phenol,
Mercaptan oder Amin unter Bildung einer ^-substituierten
Carbonsäure, die nach bekannten Methoden in das entsprechende Nitril umgewandelt werden kann, hergestellt werden.
Die Zusammensetzungen nach der Erfindung, die als Funktionsfließmittel
oder Funktionsflüssigkeiten brauchbar sind, enthalten eine größere Menge der ölartigen Flüssigkeit mit Schmierviskosität
und eine kleinere Menge an polyfunktxoneHem Nitril,
das Dichtungen in Maschinen oder anderen Betriebsanlagen zum Quellen bringt (typischerweise etwa O,O5 bis 2O,O Gewichtsteile
und vorzugsweise etwa 0,1 bis 5,O Gewichtsteile je 100 Gewichtsteile
Öl) bzw. die Bildung von Wasser-in-Öl-Emulsionen hemmt (typischerweise etwa 0,001 bis 1O,O Gewichtsteile und
vorzugsweise etwa 0,005 bis 2,O Gewichtsteile je 1OO Gewichtsteile öl). Die Erfindung schließt jedoch auch Additivkonzentrate
ein, die die besagte ölartige Flüssigkeit oder ein ähnli-
709825/0876
ches, im wesentlichen inertes, normalerweise flüssiges, organisches
Verdünnungsmittel und das polyfunktianelle Nitril umfassen,
wobei letzteres typischerweise bis zu etwa 90 % des Gewichtes des Konzentrates und gewöhnlich etwa 20 bis 90 % des .
Gewichtes deaselben -ausmacht,: Solche Konzentrate können,,wie
in der Technik bekannt ist, weiter verdünnt werden, um Funktionsfließmittel
zu bekommen.
Die vorliegende Erfindung .umfaßt auch Funktionsfließmittel und
Konzentrate, die andere Additive in Kombination mit dem polyfunktionellen
Nitril enthalten. Solche Additive sind beispielsweise Detergentien und Dispergiermittel vom aschehaltigen oder
aschelosen Typ, Korrosions- und Oxidationsinhibitoren, den Stockpunkt'erniedrigende Mittel, Mittel für extremen Druck,
Viskositätsindexverbesserer, Reibungsmodifiziermittel, Farbstabilisatoren
und Antischaummittel. .
Die aschehaltigen Detergentien sind beispielsweise öllösliche
neutrale und basische Salze von Alkali- oder Erdalkalimetallen mit Sulfonsäuren, Carbonsäuren oder organischen Phosphorsäuren,
die durch wenigstens eine direkte Kohlenstoff-Phosphorbindung
gekennzeichnet sind,, wie jene, die man durch Behandlung eines
Olefinpolymers (wie Polyisobuten mit einem Molekulargewicht
von 1000) mit einem phosphorisierenden Mittel, wie Phosphortrichlorid,
Phosphorheptasulfid, Phosphorpentasulfid, Phosphortrichlorid-und
Schwefel, weißem Phosphor mit einem Schwefelhalogenid; oder?·;Phosphorthipchloridr hergestellt wurden. Die am ,
üblichsten;-verwendeten Salze solcher Säuren.sind jene von Natrium·,

Der Ausdruck "basisches Salz" wird hier verwendet, .um.Metallsalze
zu bezeichnen, worin das Metall in s to chiome.tr is ch grö- .
ßeren Mengen als der organische Säurerest vorliegt— Die üblicherweise verwendeten Methoden zur Herstellung der basischen
Salze sind ein Erhitzen einer Mineralöllösung einer Säure mit einem stöchiometrischen Überschuß eines Metallneutralisationsmittels,
wie Metalloxid, Metallhydroxid,. Metallcarbonatr .Metallbicarbonat
oder Metallsulfid,, auf eine Temperatur, oberhalb
50 C und Filtration der resultierenden Masse. Die Verwendung, eines "Promotors" in der Neutralisationsstufe, um die Einarbeitung
eines großen Überschusses an Metall zu unterstützen, ist ebenfalls
bekannt. Beispiele von Verbindungen, die als der. Promotor brauchbar sind, sind etwa phenolische Substanzen, wie
Phenol, Naphthol, Alky!phenol, Thiophenol, sulfuriertes Alkylphenol
und Kondensationsprodukte von Formaldehyd mit einer phenolischen Substanz, Alkohole, wie Methanol, 2-Propanol, Octylalkohol,
Cellosolve, Carbitol, Äthylenglycol, Stearylalkohol
und Cyclohexylalkohol, und Amine, wie Anilin, Ph.enylendiam.in,
Phenothiazin, Phenyl-ß-naphthylamin und Dodecylamin. Eine besonders
wirksame Methode zur Herstellung der basischen Salze besteht darin, daß man eine Säure mit einem Überschuß eines
basischen Erdalkalineutralisationsmittels und wenigstens einem Alkoholpromotor vermischt und das Gemisch bei erhöhter Temperatur,
wie bei 60 bis 200 Cr mit Kohlensäure behandelt.
Aschelose Detergentien und Dispergiermittel sind beispielsweise die Interpolymeren eines öllöslichmachenden Monomers., wie Decylmethacrylat,
Vinyldecyläther oder hochmolekulares Olefin,
mit einem polare Substituenten enthaltenden. Monomer, wie Amino-

die Aminsalze, Amide und Imide öTlöslicher Monocarbonsäuren oder Dicarbonsäuren, wie von Stearinsäure, Ölsäure, TallöTsäure
und von Bernsteinsäure mit hochmolekularen Alkyl- oder Alkenylsubstituenten. Besonders brauchbar als aschelose Detergentien
sind die acylierten Polyamine und ähnliche Stickstoffverbindungen,
die wenigstens etwa 54 Kohlenstoffatome enthalten und in der US-PS 3 272 746 beschrieben sind. Reaktionsprodukte
solcher Verbindungen mit anderen Reagentien, wie Borverbindungen, Phosphorverbindungen, Epoxiden, Aldehyden, organischen
Säuren und dergleichen, und Ester von kohlenwasserstoffsubstituierten
Bernsteinsäuren, wie sie in der US-PS 3 381 Ο22 beschrieben sind.
Mittel für extremen Druck und Korrosionsinhibitoren sowie Oxidationsinhibitoren
sind beispielsweise chlorierte aliphatische Kohlenwasserstoffe, wie chloriertes Wachs, organische Sulfide
und Polysulfide, wie Benzyldisulfid, Bis-(chlorbenzyl)-disulfid,
Dibutyltetrasulfid, sulfurierte Methylester von ölsäure,
sulfuriertes Alkylphenol, sulfuriertes Dipenten und sulfuriertes Terpen, phosphosulfurierte ,Kohlenwasserstoffe, wie das
Reaktionsprodukt eines Phosphorsulfids mit Terpentin oder Methyloleat, Phosphorester, wie hauptsächlich Dikohlenwasserstoffund
Trxkohlenwasserstoffphosphite, wie Dibutylphosphit,
Diheptylphosphit, Dicyclohexylphosphit, Pentylphenylphosphit,
Dipentylphenylphosphit, Tridecylphosphit, Distearylphosphit,
Dimethylnaphthylphosphit, Oleyl-4-pentylphenylphosphit, polypropylen
(Molekulargewicht 500)-substituiertes Phenylphosphit, diisobutylsubstituiertes Phenylphosphit, Metallthiocarbamat,
709825/0876
wie Zinkdioctyldithiocarbamat und Bariumheptylphenyldithiocarbamat,
Phosphordithioate von Metallen der Gruppe II, wie Zinkdicyclohexylphosphorodithioat, Zinkdiocty!phosphorodithioat,
Bariumdi-(heptylphenyl)-phosphorodithioat, Cadmiumdinonylphosphorodithioat
und das Zinksalz einer Phosphorodithiosäure, die durch Umsetzung von Phosphorpentasulfid mit einem äquimolaren
Gemisch von Isopropylalkohol und n-Hexylalkohol gewonnen
wurde.
