  • Description


      Overview Trimethylsilanol has a boiling point of 100℃. Autoignition point is 395℃. Relative density is 0.8112 (20/4℃), and refractive index is 1.3880 (20℃). It is easy to dehydrate and condense into hexamethyldisiloxane. It can be prepared by hydrolysis of trimethylchlorosilane. In the preparation of silicone oil and silicone rubber, its condensate, hexamethyldisiloxane, can be used as an end-capping group. The hydroxyl group in the Si-O bond of trimethylsilanol is unstable. Under the action of acid or alkali, or under heating, it condenses and dehydrates to form hexamethyldisiloxane. Application Compared with the corresponding carbon alcohol, trimethylsilanol has stronger acidity and can react with lithium aluminum tetrahydride. The Si-OH bond can be reduced to the Si-H bond. It can be used as an end-capping agent for straight-chain polysiloxane. It is hydrophobic and is the most important intermediate for the preparation of silicone alcohol salts and various polysiloxane products, including silicone oil, silicone rubber and silicone resin. It has a wide range of uses and great economic value and application prospects.
