Abstract: A process for producing silanes represented by the general formula SI.sub.n H.sub.2n+2 wherein n is 1 or 2, which comprises (a) preparing a silicon-magnesium alloy containing at least one element selected from the goup 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 Si.sub.2 H.sub.6 formed to SiH.sub.4 formed.

Abstract: A process for disproportionating silanes, which comprises contacting a silane having at least one Si--H bond represented by the general formulaR.sub.l H.sub.m SiX.sub.4-(l+m)wherein R represents an alkyl or aryl group, X represents a halogen atom or an alkoxy group, l is 0, 1 or 2, and m is 1, 2 or 3 and l+m is 1, 2 or 3, and when l is 2, R's may be identical or different, and when l+m is 1 or 2, X's may be identical or different, with a reaction product of a strong acid-type cation exchange resin with an amine and disproportionating the silane.

Abstract: A process for producing silicon hydrides represented by the general formula Si.sub.n H.sub.2n+2 wherein n is a positive integer of 1 to 6, which comprises reacting a silicon-containing alloy with an aqueous solution of an acid in the presence of at least one inert organic solvent having a boiling range of from -60.degree. C. to 250.degree. C.

Abstract: Disclosed is a process for the preparation of polyamide compounds by reacting at least one polycarboxylic acid with at least one diisocyanate in the presence of a catalyst comprising at least one mono-alkali metal salt of dicarboxylic acid. The polyamide compounds prepared by this process have a substantially linear configuration and a high degree of polymerization and, therefore, are suitable for the manufacture of fibers, films and molded articles.
