Dimethyl(vinyl)silane - Introduction
Dimethylvinylsilane, chemical formula is CH3Si(CH3)(CH2CH = CH2), belongs to the organic silicon compound. The following is a description of its main Properties, Uses, methods and safety information:
Nature:
1. Appearance: Dimethylvinylsilane is a colorless transparent liquid.
2. Melting Point:-110 ℃
3. Boiling point: 155 ℃
4. Density: 0.79g/cm³
5. Solubility: Dimethylvinylsilane is soluble in organic solvents, such as alcohols, ethers and aromatic hydrocarbons.
Use:
1. As a silane coupling agent: Dimethylvinylsilane can be combined with inorganic particles or organic particles to produce chemical bonds on the surface, used as a modifier for rubber, plastics and coatings to improve product adhesion and moisture resistance.
2. As a crosslinking agent: Dimethylvinylsilane can be crosslinked with polymers for the preparation of silica gel, silicone rubber and coating crosslinking system, improve the strength and wear resistance of materials.
3. As a surface treatment agent: Dimethylvinylsilane can be used to prepare chemical products such as waterproofing agent, anti-sticking agent, anti-corrosion agent and anti-wear agent.
4. Used in the electronics industry: Dimethylvinylsilane can be used as a component of electronic packaging materials, semiconductor materials and liquid crystal displays.
Method:
Dimethylvinylsilane is typically prepared by a vinylation reaction. A common preparation method is to combine dichlorodimethylsilyl ((CH3)2SiCl2) with lithium methyl vinyl aluminum hydride (LiAlH(CH3)CH2CH = CH2) in an anhydrous solvent (such as tetrahydrofuran) in the reaction, the formation of Dimethylvinylsilane.
Safety Information:
1. Dimethylvinylsilane is irritating. Please avoid contact with skin and eyes, and ensure that appropriate protective measures are taken during operation, such as wearing gloves, goggles and protective clothing.
2. Avoid inhalation of Dimethylvinylsilane vapor, should be used in a well-ventilated place.
3. Dimethylvinylsilane is a flammable liquid and should be kept away from fire and high temperature.
