Abstract: Advances in utilizing the organosilicon high-boiling components formed during the preparation of methylchlorosilane via direct synthesis to produce valuable methylchlorosilanes are reviewed. The catalytic conversion of the organosilicon high-boiling components to methyldichlorosilanes by splitting decomposition is particularly presented. The utilization of organosilicon high-boiling components in China is briefly described. The development of utilizing organosilicon high-boiling components is discussed.
