methyl chloride[′meth·əl ′klȯr‚īd]
CH3C1; a colorless gas with a distinctive sweet odor. Boiling point, −24.1°C ; density relative to air, 1.785. It dissolves readily in organic solvents but is only slightly soluble in water. In volume concentrations of 8.2–19.7 percent, it reacts with air to form explosive mixtures. It exhibits properties characteristic of alkyl halides. It is prepared commercially by the chlorination of methane. Methyl chloride is widely used as a methylating agent in the manufacture of silicone rubber, dyes, and other products.
