Description
Verfahren zur Herstellung von monomeren Organosiliciumverbindungen Nach dem Verfahren des älteren Patents 972 855 kann man monomere Organosiliciumverbindungen dadurch herstellen, daß man Silicium und Fluor enthaltende Verbindungen, bei denen das Fluor an Silicium gebunden ist, mit Aluminiumtrialkylen bei erhöhter Temperatur, vorzugsweise bei etwa. 200 bis 300° C. umsetzt.Process for the preparation of monomeric organosilicon compounds To The method of the earlier patent 972,855 can be used to produce monomeric organosilicon compounds by preparing silicon and fluorine-containing compounds in which the fluorine is bonded to silicon, with aluminum trialkyls at elevated temperature, preferably at about. 200 to 300 ° C.
Demgegenüber wurde gefunden, daß man monomere Organosiliciumverbindungen auch herstellen kann, indem man Salze der Kieselfluorwasserstoffwäure mit Organoaluminiumverbindungen der allgemeinen Formel RnAlF3-n, worin R eine Alkyl-oder Arylgruppe und/1 = i oder 2 bedeutet, bei erhöhter Temperatur, vorzugsweise bei etwa 200 bis 300°C, umsetzt. In contrast, it has been found that monomeric organosilicon compounds can also be prepared by adding salts of hydrofluoric acid with organoaluminum compounds of the general formula RnAlF3-n, where R is an alkyl or aryl group and / 1 = i or 2 means, at elevated temperature, preferably at about 200 to 300 ° C, is reacted.
Verschieden stark alkylierte Siliciumverhindungen können je nach dem Mischungsverhältnis von n Alkylaluminiumfluorid zu den Salzen der Kieselfluorwasserstoffsäure entstehen. Different strongly alkylated silicon compounds can depending on the mixing ratio of n alkyl aluminum fluoride to the salts of silicofluoric acid develop.
Die Reaktion kann auch unter Druck erfolgen. The reaction can also take place under pressure.
Beispiel i 104. Teile Diäthylaluminiumfluorid wurden mit W8 Teilen Natriumsilicofluorid im MIbad bis auf 225°C erhitzt. Bei dieser Temperatur bildeten sich in exothermer Rektion Äthylfluorislane und Tetraäthylsilan. Die einzelnen Verbindungen wurden nach Destillation in folgender prozentualer Zusammensetzung erhalten: 15% Si(C2H5)F3, 45% Si(C2H5)2F3, 15% Si(C2H5)3F, 25% Si(C2H5)4. Example i 104. parts of diethylaluminum fluoride were mixed with W8 parts Sodium silicofluoride in the MIbath except for Heated to 225 ° C. At this Temperature, ethyl fluoroislane and tetraethylsilane formed in an exothermic reaction. The individual compounds were in the following percentage composition after distillation obtained: 15% Si (C2H5) F3, 45% Si (C2H5) 2F3, 15% Si (C2H5) 3F, 25% Si (C2H5) 4.
Die Umsetzung, bezogen auf eingesetztes Diäthylaluminiumfluorid, war quantitativ. The implementation, based on the diethylaluminum fluoride used, was quantitative.
B e i s p i e l 2 I88 Teile Äthylaluminiumdifluorid wurden mit ige Teilen Natriumsilicofluorid bis auf 300° C erhitzt. Es wurden erhalten: 40% Si(C2H5)F3. 35% Si(C2H5)2F2, Rest Si(C2H5)3F und Si(C2H5)4. B e i s p i e l 2 188 parts of ethylaluminum difluoride were mixed with ige Parts of sodium silicofluoride heated up to 300 ° C. The following were obtained: 40% Si (C2H5) F3. 35% Si (C2H5) 2F2, remainder Si (C2H5) 3F and Si (C2H5) 4.
