Abstract
Silicone intermediates are prepared by alkoxylating or aralkoxylating a mixture of organo-silicon halides having the formula RnSi4-n, wherein R represents an alkyl or aryl radical which may be the same or different, X represents a halogen atom and n any integer from 1 to 3 inclusive, to form a mixture of compounds of the general formula RnSi(OR1)4-n, wherein R and n have the above significance and OR1 represents any alkoxy or aralkoxy group, and are then separated by fractional distillation. The separated alkoxy or aralkoxy silanes may be hydrolysed and the resulting silicols condensed inter-molecularly to form a silicones.ALSO:Silicone intermediates are prepared by alkoxylating or aralkoxylating a mixture of organo-silicon halides having the formula RnSiX4-n, wherein R represents an alkyl or aryl radical which may be the same or different X represents a halogen atom and n integer from 1 to 3 inclusive, to form a mixture of compounds of the general formula RnSi(OR1)4-n, wherein R and n have the above significance and OR1 represents any alkoxy or aralkoxy group, and are then separated by fractional distillation. The separated alkoxy or aralkoxy silones may be hydrolysed and the resulting silicol condensed inter-molecularly to form a silicone. In examples, a mixture of p trimethyl-silicon-chloride, dimethyl-silicon dichloride and methyl-silicon trichloride is reacted with ethyl alcohol or n-butyl alcohol and the resulting mixture of methyl ethoxy or methyl-n-butoxy silones is fractionated.
