Description

Verfahren zur Herstellung von Arsen-, Antimon- und Wismutalkylen Es wurde gefunden, daß Alkyle der Elemente Arsen, Antimon und Wismut in hohen Ausbeuten und von großem Reinheitsgrad hergestellt werden können durch Umsetzung der dreiwertigen Chloride dieser Elemente mit Aluminiumtrialkylen, deren Ätheraten oder Alkylaluminiumchloriden unter Zusatz von Alkalic:hloriden, insbesondere von Na Cl.Process for the production of arsenic, antimony and bismuth alkyls Es it was found that alkyls of the elements arsenic, antimony and bismuth in high yields and can be made of a high degree of purity by reacting the trivalent Chlorides of these elements with aluminum trialkyls, their etherates or alkyl aluminum chlorides with the addition of alkali: chlorides, especially Na Cl.

Die Reaktionen verlaufen beispielsweise folgendermaßen: As C13+AIR3+NaC1 -@As R3+NaAlC14 oder Sb C13+3 R,AlCl-, , 3 NaCI-@ SbR3+3 NaAIRCh. Durch den erfindungsgemäßen Zusatz von Alkalichlorid, vorzugsweise Natriumchlorid, wird bewirkt, daß das bei der Reaktion entstehende A1 C13, das die Umsetzung durch Nebenreaktionen, Verstopfung der Apparaturenteile u. dgl. erschweren würde, durch Komplexbildung abgeschieden wird und mühelos aus dem Reaktionsgefäß entfernt werden kann (z. B. durch Herausschmelzen, Herauslösen oder Austragen).The reactions are as follows, for example: As C13 + AIR3 + NaC1 - @ As R3 + NaAlC14 or Sb C13 + 3 R, Al Cl- ,, 3 NaCl- @ SbR3 + 3 NaAIRCh. The addition of alkali metal chloride, preferably sodium chloride, according to the invention means that the A1 C13 formed during the reaction, which would make the reaction more difficult due to side reactions, clogging of the apparatus, etc., is deposited through complex formation and can be easily removed from the reaction vessel (e.g. by melting out, dissolving out or discharging).

Die Reaktion kann in Gegenwart oder Abwesenheit von Lösungs-, Suspensions- oder Verdünnungsmitteln durchgeführt werden.The reaction can be carried out in the presence or absence of solution, suspension or diluents.

Mitunter ist es zweckmäßig, als Lösungsmittel das herzustellende Elementallzvl selbst zu verwenden. Die Reaktion wird zweckmäßigerweise bei Atmosphärendruck durchgeführt, doch kann Unter- oder Überdruck ebenfalls angewendet werden.Sometimes it is expedient to use the Elementallzvl to be produced as the solvent to use yourself. The reaction is expediently carried out at atmospheric pressure, however, negative or positive pressure can also be used.

Das Verfahren kann so durchgeführt werden, daß eine Lösung der Alkylaluminiumverbindung in einem geeigneten Lösungsmittel, wie Methylenchlorid, Chlorbenzol, Methylnaphthalin und Mineralöl, mit Alkalichlorid versetzt wird, worauf das Element(III)-chlorid entweder im festen, flüssigen oder gasförmigen Zustande eingetragen wird. Man kann auch umgekehrt in eine Lösung bzw. Suspension des Element(III)-chlorids in einem geeigneten Lösungs- bzw. Suspensionsmittel (auch in dem herzustellenden Elementalkyl selbst) die Alkylaluminiumverbindung bzw. deren Lösung zugeben.The process can be carried out using a solution of the alkyl aluminum compound in a suitable solvent such as methylene chloride, chlorobenzene, methylnaphthalene and mineral oil, is added with alkali chloride, followed by element (III) chloride is entered either in the solid, liquid or gaseous state. One can also vice versa in a solution or suspension of the element (III) chloride in one suitable solvent or suspension medium (also in the element alkyl to be produced even) add the alkylaluminum compound or its solution.

Beispiel 1 Nach der Gleichung 3 Al R3+2 As C13+3 Na C1 -> 2 As R3+3 NaA1 C13 R wurde zu einer Lösung von 57 Gewichtsteilen Aluminiumtriäthyl in 150 ccm Hexan, welche außerdem 33 Gewichtsteile Natriumchlorid suspendiert enthielt, eine Lösung von 60,5 Gewichtsteilen Arsentrichlorid in 100 ccm Hexan zugetropft. Reaktionstemperatur 70 bis 80° C. Nach Abdestillieren des Lösungsmittels wurden 42 Gewichtsteile Arsentriäthyl, welches 1% Chlor enthielt, erhalten, was einer Ausbeute von über 801/a der Theorie entsprach.Example 1 According to the equation 3 Al R3 + 2 As C13 + 3 Na C1 -> 2 As R3 + 3 NaA1 C13 R became a solution of 57 parts by weight of aluminum triethyl in 150 ccm of hexane, which also contained 33 parts by weight of sodium chloride in suspension, a solution of 60.5 parts by weight of arsenic trichloride in 100 cc of hexane was added dropwise. Reaction temperature 70 to 80 ° C. After distilling off the solvent were 42 parts by weight of arsenic triethyl, which contained 1% chlorine, were obtained, which is a yield of over 801 / a corresponded to the theory.

Wurde ohne Natriumchloridzusatz gearbeitet, so enthielt das äthylierte Arsenprodukt 32% Chlor. Beispiel2 In ein Gemisch von 29,7 Gewichtsteilen Aluminiumtriäthyl, 83 Gewichtsteilen Hexan und 16 Gewichtsteilen Natriumchlorid wurden bei einer Reaktionstemperatur von 70° C sukzessiv insgesamt 54,8 Gewichtsteile Wismuttrichlorid eingetragen. Nach 1/2stündiger Reaktion wurde das Lösungsmittel vertrieben und durch Vakuumdestillation 43 Gewichtsteile an reinem, chlorfreiem @,#Tismuttriäthyl erhalten, welches einer Ausbeute von über 85% der Theorie entsprach.If no sodium chloride was added, it contained the ethylated Arsenic product 32% chlorine. Example 2 In a mixture of 29.7 parts by weight of aluminum triethyl, 83 parts by weight of hexane and 16 parts by weight of sodium chloride were added at a reaction temperature from 70 ° C entered successively a total of 54.8 parts by weight of bismuth trichloride. To 1/2 hour reaction, the solvent was driven off and vacuum distilled 43 parts by weight of pure, chlorine-free @, # Tismuttriethyl obtained, which one Yield of over 85% corresponded to theory.

Wurde derselbe Ansatz ohne Natriumchloridzusatz durchgeführt, so betrug die Ausbeute 32% der Theorie, und der Chlorgehalt des Produkts lag bei 60/0. Beispiel 3 Zu einer Lösung von 45,8 Gewichtsteilen Diäthylaluminiumchlorid in 100 Gewichtsteilen Hexan wurden 24,5 Gewichtsteile Natriumchlorid eingetragen, woraufhin bei einer Reaktionstemperatur von 70° C 40 Gewichtsteile Wismuttrichlorid zugesetzt werden. Nach 1/2stündiger Reaktion wurde das Lösungsmittel abdestilliert und das entstandene Wismuttriäthyl durch Vakuumdestillation gewonnen. Erhalten wurden 32 Gewichtsteile dieser Verbindung, welches einer Ausbeute von etwa 85'% der Theorie entsprach.If the same approach was carried out without the addition of sodium chloride, the value was the yield was 32% of theory, and the chlorine content of the product was 60/0. example 3 To a solution of 45.8 parts by weight of diethyl aluminum chloride in 100 parts by weight Hexane was added 24.5 parts by weight of sodium chloride, whereupon one Reaction temperature of 70 ° C 40 parts by weight of bismuth trichloride are added. After 1/2 hour of reaction, the solvent was distilled off and the resultant Bismuth triethyl obtained by vacuum distillation. 32 parts by weight were obtained this compound, which corresponded to a yield of about 85% of theory.
