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. It is also widely used
as solvent, extractant, propellant, cooling agent, local anesthetic,
methylation reagent, and used in the production of pesticides, pharmaceuticals,
fragrances and so on. About 80 per cent of the chloromethane produced worldwide
is used to produce methyl chlorosilane and tetramethyl lead, but the
consumption of tetramethyl lead is declining because the anti-knock compounds
in gasoline are gradually being replaced by lead-free substances.
3. Mainly used as raw
materials for silicone, also used as solvents, refrigerants, fragrances and so
on.
