Abstract

Pure dimethyl hydrogen chlorosilane is obtained from a mixture distilling at a temperature of from 33 to 37 DEG C., from the direct synthesis of methyl chlorosilanes, by separating off impurities which otherwise cannot be removed by distillation, by adding hexachloroplatinic acid to the mixture, followed by fractional distillation.

They can be used to obtain resins, lacquers, liquids, rubbers with enhanced thermal-oxidative stability. A method is known for preparing this compound by reacting organochlorosilanes with o-chlorophenyls at 500-700 ° C. The advantages of such a method are to carry out the synthesis at high temperatures (700 ° C), a significant percentage of bottom fraction, and the use of trichlorosilane (the ratio between o-chloridiphenyl and trichlorosilane is at least 1: 2).
