Vapor-phase hydrosilylation using platinum complex in polyethylene-glycol medium supported on silica gel as a catalyst

摘要

Hydrosilylation of acetylene with trichlorosilane or trimethoxysilane was carried out using a vapor-phase flow reactor with use of tetraammineplatinum (II) chloride in polyethylene-glycol medium supported on silica gel as a catalyst. While supported platinum metal catalyst and supported platinum complex catalyst were drastically deactivated, this supported liquid-phase catalyst using polyethylene glycol was very active and stable, furthermore is prepared readily from easily available materials, tetraammineplatinum (II) chloride, polyethylene glycol and silica gel. The supported liquid-phase catalyst using polymer as a liquid phase is expected to have applications in various vapor-flow reactions.
