Abstract

A chlorosilane having at least one hydrogen bonded to silicon is disproportionated by contacting the heated silane with an organic amine, a salt thereof, or a complex thereof with a chlorosilane, a heterocyclic nitrogen base, hydrogen cyanide or an aliphatic or substituted aliphatic mono-, di-, or polynitrile as catalyst. Exemplified catalysts are trimethylamine, trimethylamine hydrochloride, trimethylamine-trichlorosilane complex, diethylamine, triethylamine, cetyl dimethyl amine, N,N1-tetraethyl ethylene diamine, pyridine, hexamethylene tetramine, acetonitrile, polyacrylonitrile, succinonitrile, glutaronitrile, adiponitrile, pimelonitrile, azelaionitrile, sebaconitrile, and suberonitrile, and 1-15 per cent may be used. The reaction may be effected by heating the chlorosilane and catalyst in an autoclave at say 150-200 DEG C., by passing chlorosilane vapour over the catalyst, or by heating under atmospheric pressure in a flask with a distillation column to secure refluxing below 200 DEG C. with the lower boiling component distilling off. The Specification refers to converting trichlorosilane to dichlorosilane and silicon tetrachloride, and dichlorosilane to mono and trichlorosilanes. Nitrile catalysts may be activated by heating with a chlorosilane at above 150 DEG C., distilling off all low-boiling compounds to leave a high-boiling mixture, e.g. ethyldichlorosilane and adiponitrile. With activated catalysts the reaction temperature may be below 100 DEG C., e.g. 30-60 DEG C.ALSO:A chlorosilane having at least one hydrogen bonded to silicon is disproportionated by contacting the heated silane with an organic amine, a salt thereof, or a complex thereof with a chlorosilane, a heterocyclic nitrogen base, hydrogen cyanide or an aliphatic or substituted aliphatic mono-, di-, of polynitrile as catalyst.
