Abstract:
A concerted process for preparing silanes of the formula 1:RaSiHbCl4-a-bâ€ƒâ€ƒ(1) whereR 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/or oligosilanes whose radicals are selected from among H, R and Cl, or mixtures thereof, wherein hydrogen chloride gas is prepared by combusting H2 and Cl2 in the concerted process, and wherein said reactants are introduced together with H2 and Cl2 into a reactor, or into a zone of the reactor, whereby said reactants contact hydrogen chloride still hot from combustion of H2 and Cl2 within the reactor.
