Abstract

The five different reaction mechanisms for the gas-phase chlorosilylation of silica have been studied. A comprehensive, unified approach to the problem, based on effectiveness, surface coverage and stoichiometry of silylation is presented. It is proven that all five reactions do occur, but each mechanism has a preference for a rather limited region of pretreatment and reaction temperatures.
