Silicone oil is generally a colorless (or light yellow), odorless, non-toxic, non-volatile liquid. Silicone oil is insoluble in water, methanol, ethylene glycol and 2-ethoxyethanol, miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene, and slightly soluble in acetone, dioxane, ethanol and Butanol. It has a small vapor pressure, high flash point and fire point, and low freezing point. As the number of chain segments n increases, the molecular weight increases and the viscosity also increases. Therefore, silicone oil can have various viscosities, from 0.65 centistokes to millions of centistokes. If you want to prepare low-viscosity silicone oil, you can use acidic clay as a catalyst and telomerize at 180°C, or use sulfuric acid as a catalyst and telomerize at low temperature to produce high-viscosity silicone oil or viscous materials. catalyst.
