Octamethylcyclotetrasiloxane CAS NO.556-67-2
Name:Octamethylcyclotetrasiloxane
CAS No.:556-67-2
Appearance: colorless transparent oily liquid
Molecular formula: C8H24O4Si4
EINECS No.: 209-136-7
Molecular Weight: 296.6158
Molecular structure:
Production method
Add dimethyldichlorosilane dropwise to water, maintain the temperature at 30-40°C, separate the layers, remove the acid water, hydrolyze the oil with sodium hydroxide solution, add the hydrolyzate and 0.5%-2% potassium hydroxide to crack In the kettle, cracking was carried out at 120-140°C and 99.8kPa vacuum. The lysate is fractionated, and the fractions at 173-176 °C are collected to obtain octamethylcyclotetraoxysilane.
use
This product is an intermediate of silicone oil and silicone rubber.
Used as a raw material for silicone, also used in the electronics industry
Used in the manufacture of high tear-resistant silicone rubber products, and also used in the synthesis of other polymer compounds
It is used as an intermediate in the preparation of silicone oil, and is also used in the insulation and moisture-proof of radio parts.
