PROCESS FOR PRODUCING SILANES

摘要

A process for producing silanes represented by the general formula SinH2n+2 wherein n is 1 or 2, which comprises (a) preparing a silicon-magnesium alloy containing at least one element selected from the group consisting of Li, Na, K, Ca, Ba, Ti, Zr, Nb, Cr, Mo, Mn, Fe, Co, Ni, Pd, Cu, Ag, Zn, Cd, Al, Sn, Pb, Bi, Se, S and C as a third component element; (b) reacting the alloy containing the third component element with an acid in an ammonia solvent; and (c) thus, varying the ratio of Si2H6 formed to SiH4 formed.
