Although there are many types of organosilicon monomers, the starting materials for production are limited to a few organosilicon monomers. Among them, dimethyldichlorosilane accounts for the absolute amount, followed by phenylchlorosilane, the former The dosage accounts for more than 90% of the total amount of monomers. In addition, trimethylchlorosilane, ethyl and propylchlorosilane, vinylchlorosilane, etc. are also indispensable raw materials for the production of certain varieties.
　　 Organochlorosilanes (methylchlorosilane, phenylchlorosilane, vinylchlorosilane) are the foundation of the entire organosilicon industry, and methylchlorosilane is the backbone of the organosilicon industry. Most of the silicone polymers are polydimethylsiloxane made from dimethyldichlorosilane as the base polymer, and then introduce other groups such as phenyl, vinyl, chlorophenyl, fluoroalkyl Etc. to meet special needs. The production process of methylchlorosilane is long and technically difficult. It is a technology-intensive and capital-intensive industry. Therefore, major foreign companies are building large-scale and concentrated basic factories, and the post-processed products are distributed according to usage and market conditions.
        The raw materials for preparing silicone oil, silicone rubber, silicone resin and silane coupling agent are various organic silicon monomers. Thousands of organic silicon products can be produced from several basic monomers. Organic silicon monomers mainly include: methylchlorosilane (referred to as methyl monomer), phenylchlorosilane (referred to as phenyl monomer), methylvinylchlorosilane, ethyltrichlorosilane, propyltrichlorosilane, Vinyltrichlorosilane, γ-chloropropyltrichlorosilane and fluorosilicone monomers. Among them, methylchlorosilane is the most important, and its dosage accounts for more than 90% of the total monomer total, followed by phenylchlorosilane.
The key to the development of any polymer material lies in the development of monomer technology. The silicone industry is characterized by concentrated monomer production and dispersed product processing. Therefore, monomer production occupies an important position in the organosilicon industry, and the production level of monomer directly reflects the development level of the organosilicon industry.
