Nature
polydimethylsilyl ether is a colorless transparent viscous liquid. Odorless and tasteless. Insoluble in water and ethanol, soluble in carbon tetrachloride, benzene, chloroform, ether, toluene and other organic solvents.
Preparation Method
octamethylcyclotetrasiloxane is obtained by hydrolysis, neutralization, cracking and fractionation of dimethyldichlorosilane, water and solvent raw materials, and hexamethyldisiloxane is used as the terminal blocking group to adjust the molecular weight, with sodium hydroxide or concentrated sulfuric acid as catalyst polymerization.
