Abstract
Alkoxy chlorosilanes are prepared by reacting in the liquid phase one or more esters of the formula R4-nSi(OR1)n, wherein R is an alkyl or aryl radical, R1 is an alkyl radical and n is an integer from 1 to 4, with one or more chlorosilanes of the formula R4-mSiClm, wherein R is an alkyl or aryl radical and m is 2 or 3, whereby interchange is accomplished between at least one alkoxy radical and a chlorine atom. The reaction may be effected in the presence of free acid, e.g., hydrogen chloride, which may be formed in situ. Products obtained by the process are of the type R2SiOR1Cl, RSi(OR1)2Cl, RSi(OR1)Cl2 and ClSi(OR1)3, wherein R and 1 have the above significance. In the examples, alkoxy chlorosilanes of the above types in which R1 represents methyl and ethyl groups and R represents a methyl group are prepared.
