Applications
Trimethylchlorosilane has the advantages of high yield, mild conditions, and wide applicability, and is widely used in the synthesis of spices and organic drugs. Its demand is increasing, and trimethylchlorosilane is mainly obtained from the conversion of trimethylsilyl ether. Trimethylchlorosilane is widely used as a protective group for functional groups such as hydroxyl, amino, and carboxyl in chemical and pharmaceutical synthesis. It can also be used as a sealing agent for organosilicon polymer in petroleum production and other processes, playing a role in regulating the molecular weight of polymers. In chemical synthesis, trimethylchlorosilane is dissociated after completing its protective effect, resulting in the byproduct hexamethylsiloxane. Therefore, how to convert hexamethylsiloxane into trimethylchlorosilane for repeated use is an important measure to reduce production costs.
This product is mainly used as an intermediate in the production of organosilicon polymers and other products, as well as as as a raw material for polymer compound sealing agents, desiccants, dehydrators, high-temperature adhesives, and resins. Used in the synthesis of cephalosporins I and V in pharmaceutical production.
This product can be used to produce various organic silicon compounds and is the main raw material for producing hexamethyldisilazane and hexamethyldisiloxane.
This product can be used as an alkylating agent and as a group protector in pharmaceutical and chemical production
