Title: Preparation of organohalogenomonosilanes from organohalogenopolysilanes
IPC: C07F7/12
Filed: 1955-03-01
Abstract: Organohalogenomonosilanes are obtained from organohalogenopolysilanes by heating the latter with a hydrogen halide in the presence of a tertiary amine or salt thereof or with a hydrogen halide salt of a tertiary amine.  It is preferred that the halogen of the hydrogen halide be the same as the halogen of the silane.  Suitable amines are tri-(n-butyl)-amine, lauryl dimethyl amine, trimethyl-, triethyl- and other trialkyl - amines; triphenyl - and tribenzylamines; N,N - dimethyl aniline, N,N - dimethyl benzylamine, N-methyl morpholine, pyridine, quinoline, N-ethyl- and N-methyl-piperidine, isoquinoline and the picolines.  The salts may be of an organic or inorganic acid. The reaction may be effected by heating a mixture of the amine and polysilane to the boiling point of the mixture, e.g. 100 DEG  to 150 DEG  C., while introducing the hydrogen halide vapour, and removing the monosilanes.  The amount of amine is generally from 0.001 to 4 or 5 mols. of polysilane with at least 0.25 mol. of hydrogen halide.  A solvent may be employed, e.g. xylene, benzene, toluene and chlorobenzene.  Examples are given of the degradation of a mixture consisting mainly of methyl chlorodisilanes, prepared as described in Specification 575,667, [Group IV], from which are formed dimethyl monochlorosilane, trimethyl chlorosilane, methyl dichlorosilane dimethyl dichlorosilane and methyl trichlorosilane.
