Hexamethyldisiloxane, a colorless transparent liquid, is easily deliquescent. Insoluble in water, soluble in many organic solvents. Used as silicone oil, silicone rubber, medicine, gas chromatography stationary liquid, analytical reagent, water repellent, etc. It is produced by hydrolysis of trimethylchlorosilane. It is flammable and may cause burning if it encounters high heat, open flames, and strong oxidizers. The boiling point is 99.5°C. The flashpoint is -1.1°C. The relative density (d2525) is 0.7606. The refractive index is 1.3750. Insoluble in water, soluble in many organic solvents.
Preparation method: Take trimethylchloro(methyl)silane as raw material, hydrolyze it in water, then wash it with water and rectify it.
