FIELD: chemistry. n SUBSTANCE: proposed method of producing chloromethanes involves gas-phase thermal chlorination of methane, condensation of obtained chloromethanes, removal of methyl chloride from the condensate, obtaining a mixture of chloromethanes, distillation of this mixture with separation of the light fraction, liquid-phase chlorination of the light fraction with photochemical initiation, combination of vat fractions with products of liquid-phase chlorination, and separation of individual chloromethanes using known methods. n EFFECT: reduced formation of tetrachloromethane and increased selectivity on chloroform. n 2 cl, 1 tbl, 4 ex |
