Methylene chloride is a colorless flammable toxic gas, is an organic halide, can be produced by methane and chlorine substitution reaction, can be continued halogenation. Slightly soluble in water, soluble in ether, benzene and so on. Flammable, and air can form explosive mixtures, explosion limit 8.1% ~ 17.2% (volume). Chloromethane is hydrolyzed above 60℃ to produce methanol.

1, used in the production of methyl chlorosilane, tetramethyl lead, methyl cellulose, etc., a small amount used in the production of quaternary ammonium compounds, pesticides, used as a solvent in the production of isobutyl rubber

2、Important raw material for organic synthesis. Mainly used in the production of silicone compounds - methyl chlorosilane, and methyl cellulose. Also widely used as solvents, extractants, propellants, refrigerants, local anesthetics, methylation reagents, used in the production of pesticides, pharmaceuticals, spices and so on. About 80% of the chloromethane produced in the world is used to produce methyl chlorosilane and tetramethyl lead, but the consumption of tetramethyl lead is gradually declining because the anti-explosive compounds in gasoline are gradually being replaced by lead-free substances.

3. It is mainly used as raw material of silicone, and also used as solvent, refrigerant and spice.
