Description
technical field [0001] The invention belongs to the technical field of waste treatment, and in particular relates to an organosilicon high-boiling mixed liquid directional conversion system. Background technique [0002] Silicone materials have excellent high and low temperature resistance and electrical insulation properties, and are widely used in agriculture, industry, military and other fields. Methylchlorosilane monomer is the basic raw material for the production of various organosilicon materials, and its synthesis technology is closely related to the development of the organosilicon industry. In 1941, GE Company of the United States invented the technology of directly synthesizing methylchlorosilane, and realized industrial production in 1947; [0003] In the process of direct synthesis of organosilicon monomers, in addition to the target product dimethyldichlorosilane, there are also some by-products, including methyltrichlorosilane, trimethylchlorosilane, methyldi...
