Product description:To dimethyl dichlorosilane join the water drops, the temperature at 30 to 40 ℃, layered, put to the acid water, oily matter with sodium hydroxide solution hydrolysis, the hydrolysate and 0.5% 2% potassium hydroxide to join the cracking in the kettle, in 120-140 ℃, under 99.8 kPa vacuum pyrolysis. Cracking for fractionation, collected 173-176 ℃ fraction and eight methyl four silane oxygen.1. The goods for the silicone oil, silicone intermediate. Also used as a solvent, the preparation of methyl silicone oil. 2. Used in hair care cosmetics, such as hair conditioner, hair agent, fixing agent, spray, dry hair lotion, etc., can make hair smooth, soft and easy to comb. This product is a kind of organic silicon monomer, synthesis of organic silicon polymer.
