  2. Chloromethane - Wikipedia

    en.wikipedia.org/wiki/Chloromethane

    A smaller amount of chloromethane is produced by treating a mixture of methane with chlorine at elevated temperatures. This method, however, also produces more highly chlorinated compounds such as dichloromethane, chloroform, and carbon tetrachloride. For this reason, methane chlorination is usually only practiced when these other products are ...

    en.wikipedia.org/wiki/Organochlorine_chemistry

    Several billion kilograms of chlorinated methanes are produced annually, mainly by chlorination of methane: CH 4 + x Cl 2 → CH 4−x Cl x + x HCl. The most important is dichloromethane, which is mainly used as a solvent. Chloromethane is a precursor to chlorosilanes and silicones.

  4. Dichloromethane - Wikipedia

    en.wikipedia.org/wiki/Dichloromethane

    DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products. In this way, an estimated 400,000 tons were produced in the US, Europe, and Japan in 1993. [12] CH 4 + Cl 2 → CH ...

  5. Free-radical halogenation - Wikipedia

    en.wikipedia.org/wiki/Free-radical_halogenation

    A radical abstracts a hydrogen atom from methane, leaving a primary methyl radical. The methyl radical then abstracts Cl • from Cl 2 to give the desired product and another chlorine radical. Methane chlorination: propagation The radical will then participate in another propagation reaction: the radical chain. Other products such as CH 2 Cl 2 ...
