Octamethylcyclotetrasiloxane Uses
It is colorless, inflammable, and can not dissolve in water, but dissolve in organic solvents such as benzene, etc. It can be used to synthesize organic silicon polymer by acid or alkali catalysis to manufacture silicone oil, silicone rubber, etc. It can also be used directly as a treating agent for rubber stuffing and the raw material for cosmetics.
Preparation Method of Octamethylcyclotetrasiloxane
Dimethyl dichlorosilane is added dropwise to water, the temperature is maintained at 30-40℃, stratified, the acidic water is released, the oily substance is hydrolyzed with sodium hydroxide solution, the hydrolysate and 0.5%-2% potassium hydroxide are added into the cracking kettle and cracked at 120-140℃ and 99.8kPa vacuum. The cracked material is fractionated and the fraction is collected at 173-176°C to obtain d4 silicone octamethylcyclotetrasiloxane.
As one of silicone suppliers, we will do our best to meet all the needs of customers.
