Removal of polyfunctional silanes from organosilanes.

摘要

What is described is a process for the treatment of organosilanes to reduce the content of more highly functional silanes. The process comprises (A) contacting a mixture, the mixture comprising a major portion of the organosilane and a minor portion of the more highly functional silanes, with organosiloxanes, and a sufficient amount of a catalyst effective in promoting the reaction between the more highly functional silanes and the organosiloxane to form more highly halogenated polyfunctional siloxanes; and (B) isolating the organosilane from the polyfunctional siloxanes and the organosiloxanes by conventional means such as distillation.
