Chlorosilane monomers - Names and Identifiers
Chlorosilane monomers - Introduction
Chlorosilane monomers are a class of organic compounds containing chlorine and silicon atoms. The general formula is RnSiCl4-n, wherein R represents an organic group and n is an integer between 0 and 3. Commonly used Chlorosilane monomers include trichlorosilane (SiCl3H), dichlorodimethylsilane (CH3SiCl2H), and chloromethyltrimethylsilane (CH3SiCl3), among others.
Chlorosilane monomers have the following properties:
1. Colorless or light yellow liquid with pungent odor;
2. Soluble in organic solvents, react with water to produce hydrogen chloride and silicon hydrogen compounds;
3. Flammable, prone to fire or explosion.
Chlorosilane monomers are widely used in the chemical industry, mainly including the following aspects:
1. As a raw material for silicone rubber, silicone resin and silicone;
2. Catalyst and reducing agent for organic synthesis;
3. As a surfactant, it is used to improve the weather resistance and surface coating of materials.
The preparation of Chlorosilane monomers mainly has the following methods:
1. Alkali catalysis method: using alkali as a catalyst, the organic silane is prepared by reacting with hydrogen chloride;
2. Metal catalytic method: Chlorosilane monomers are obtained by reacting silicon with chlorine using metal catalyst;
3. Alkyl siliconization method: the alkyl chloride is prepared by reacting with metal silicon.
The use of Chlorosilane monomers requires safety precautions, including:
1. Avoid direct contact with skin, eyes and respiratory tract, and use appropriate protective measures when necessary;
2. Maintain good ventilation during operation to avoid toxic gases;
3. Avoid contact with water or moisture to avoid violent reaction;
4. Storage should be away from the fire and oxidant, to prevent the occurrence of fire or explosion.
