Process for preparing silanes

A process for preparing silanes of the formula 1: RaSiHbCl4-a-b (1) where R is methyl or ethyl, a is 0, 1, 2, or 3 and b is 0 or 1, from hydrogen chloride gas and reactants selected from among a) silicon metal, b) disilanes and oligosilanes whose radicals are selected from among H, R and Cl, and mix...

Zusammenfassung:	A process for preparing silanes of the formula 1: RaSiHbCl4-a-b (1) where R is methyl or ethyl, a is 0, 1, 2, or 3 and b is 0 or 1, from hydrogen chloride gas and reactants selected from among a) silicon metal, b) disilanes and oligosilanes whose radicals are selected from among H, R and Cl, and mixtures thereof, wherein the hydrogen chloride gas is prepared from H2 and Cl2 is a concerted process.
