The primary form of dimethyl cyclosiloxane is an organic-inorganic organic-inorganic compound that uses dimethyldichlorosilane as the main raw material and is synthesized through hydrolysis. It has silicon-oxygen (Si-O) bonds as the main chain and organic groups directly connected to the silicon atoms. compound. The primary form of dimethylcyclosiloxane has a cyclic molecular structure, mainly including hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4), and decamethylcyclopentasiloxane. (D5), dodecamethylcyclohexasiloxane (D6), and hexamethylcyclotrisiloxane (D3) and or octamethylcyclotetrasiloxane (D4) and or decamethylcyclopentasiloxane It is a colorless, transparent or milky white liquid containing more than 50% oxane (D5) and dodecamethylcyclohexasiloxane (D6). It is flammable, odorless, insoluble in water, and soluble in benzene and other organic solvents.
