Abstract

Способ получения хлорметанов хлорированием хлористого метила хлором в жидкой фазе в присутствии инициатора при повышенных температуре и давлении с последующим отбором продуктов реакции и их ректификацией, рециклом непрореагировавшего хлористого метила и получаемого метиленхлорида на хлорирование, отличающийся тем, что, с целью увеличения выхода хлороформа при одновременном увеличении соотношения получаемых хлороформа и четыреххлористого углерода, хлорирование ведут при кипении реакционной массы при давлении 4 - 8 атм, причем отбор продуктов реакции ведут из жидкой и паровой фаз с конденсацией паровой фазы при 20 - 50C с выделением образовавшегося хлористого водорода из несконденсированной паровой фазы и ректификацией продуктов хлорирования при давлении 4 - 8 атм.The method of producing chloromethanes by chlorination of methyl chloride with chlorine in the liquid phase in the presence of an initiator at elevated temperature and pressure, followed by the selection of reaction products and their rectification, recycling unreacted methyl chloride and the resulting methylene chloride for chlorination, which is different in that the ratios of chloroform and carbon tetrachloride, chlorination is carried out at the boiling of the reaction mass at a pressure of 4 - 8 atm, and the selection Recreatives Products reactions are carried from the liquid and vapor phases of the vapor phase to condensation at 20 - 50C with the release of the hydrogen chloride from the uncondensed vapor phase and the chlorination products by rectification at a pressure of 4 - 8 atm.
