More Information
Summary:organic chemistry, chemical technology. SUBSTANCE: invention describes the novel method of isolation of trimethylchlorosilane from azeotropic mixture trimethylchlorosilane/tetrachlorosilane. Method involves boiling the mixture of azeotrope and dimethyl- formamide with tetraethoxysilane. Method provides decrease of nonutilized by-side products and increase of yield of Me3SiCl up to 65-72%. EFFECT: improved method of isolation, increased yield of end product. 2 cl, 4 ex
