Effect of chloralkanes on the phenyltrichlorosilane synthesis by gas phase condensation

doi:10.1016/j.cjche.2014.11.003

Abstract

Abstract: To enhance the process of phenyltrichlorosilane synthesis using gas phase condensation, a series of chloralkanes were introduced. The influence of temperature and chloralkane amount on the synthesis was studied based on the product distribution from a tubular reactor. The promoting effect of chloralkane addition was mainly caused by the chloralkane radicals generated by the dissociation of C-Cl bond. The promoting effect of the chloromethane withmore chlorine atomswas better than thosewith less chlorine atoms. Intermediates detected fromthe reactions with isoprene and bromobenzene demonstrated that both trichlorosilyl radical and dichlorosilylene existed in the reaction system in the presence of chloralkanes. A detailed reaction scheme was proposed.
