Abstract Organosiliconmaterials are widely applied in various fields due to their excellent properties, including moisture-proof, corrosion resistance, high and low temperature resistance, non-toxic and physiological inertia. However, the production process of organosilicon monomers will produce about 7% by-products, and they are mainly composed of organochlorosilane high-boiling residues with complex composition and low commercial value. Inflammable, pungent and strong corrosive organochlorosilane high-boiling residues are greatly harmful to our health and environment. With the increasing productivity of organosilicon monomer, the efficient utilization of organochlorosilane high-boiling residues has become a diffcult problem to be solved urgently. The recycle of organochlorosilane high-boiling residues is mainly achieved through the synthesis of organosilicon downstream products and organosilicon monomers by catalytic cracking method. The catalytic cracking process needs to break the Si-Si bond and Si-C-Si bond in the presence of catalysts and convert high-boiling residues into methylchlorosilane monomers by selecting a suitable blocking reagent. Lewis acids, organic amines, transition metal elements, activated carbon and molecular sieves are main catalysts for catalytic cracking, and their operating conditions and catalytic performance are different. The cracking ratio of organochlorosilane high-boiling residues can reach more than 99%. Nevertheless, the high operation cost and complex production technology limit the further industrial application and popularization. This review article offers a retrospection of research works with respect to the catalytic cracking materials for organochlorosilane high-boi-ling residues, and the materials include aluminum-based compounds, organic amines or quaternary ammonium salts, transition metals, molecular sieves or activated carbon and metallic phosphate catalysts. We have summarized the research status and problems of the above catalysts and analyzed the development prospects. It is expected to provide an available summary for development prospect of catalytic cracking industrialization.
