METHOD OF PREPARING OF POLYETHYLSILOXANE LIQUIDS Russian patent published in 1995 - IPC

Abstract RU 2034864 C1

FIELD: heat carrier. SUBSTANCE: liquids were prepared by interaction of magnesium with a mixture of ethyl chloride, tetraethoxysilane, diethyldichlorosilane and methyltrichlorosilane taken at the molar ratio: ethyl chloride 3.0; tetraethoxysilane 0.749-1.01; diethyldichlorosilane 0.067-0.2; methyltrichlorosilane 1.246-0.35 in toluene medium at 50-100 C following by hydrolysis of prepared mixture of ethyl-substituted silanes, toluene distillation off, catalytic rearrangement of hydrolysis products and distilling for fractions. EFFECT: improved method of preparing. 2 tbl
