Properties and stability

Basic properties: Easy to hydrolyze, releasing hydrogen chloride and generating condensate of methyl vinyl silicone diol. Vapors and liquids can cause skin burns and are toxic if inhaled. Reacts with absolute ethanol to release hydrogen chloride and generate methyl vinyl diethoxysilane. Reacting with organic magnesium halide, the chlorine atom in the Si-Cl bond can be replaced by the corresponding organic group. In the presence of platinum catalyst, Si-CH=CH₂ bonds can interact with Si-H bonds.��Compounds undergo addition reactions.

Storage method

.Storage: Store sealed in a dry and ventilated place. Keep out of contact with humid air.

Synthesis method

Brief description of production method: It can be prepared by reacting methyltrichlorosilane and vinyl magnesium bromide

Purpose

Usage: Used to synthesize silicone intermediates and high molecular polymers such as silicone oil and silicone rubber.
