Abstract
1. Способ получения хлороформа путем взаимодействия четыреххлористого углерода с донором водорода в присутствии комплекса хлорида меди с четвертичными солями аммония при повышенной температуре, отличающийся тем, что в качестве донора водорода используют метиленхлорид, в качестве четвертичных аммонийных солей соединения общей формулы R3R'NCl или R2R'2NCl, где R=C1-C18 - алкил, R'-C1-C18 - алкил, хлоралкил или бензил при мольных соотношениях соль:медь 8-10:1, концентрация меди составляет 0,1-0,5 г/л, и процесс ведут при температуре 180-200°C при мольном соотношении четыреххлористого углерода и метиленхлорида 1,5-6:1. ! 2. Способ согласно п.1, отличающийся тем, что катализатор добавляют 2-4 порциями через 90-120 мин каждая. 1. A method of producing chloroform by reacting carbon tetrachloride with a hydrogen donor in the presence of a complex of copper chloride with quaternary ammonium salts at an elevated temperature, characterized in that methylene chloride is used as a hydrogen donor, as compounds of the general formula R3R'NCl or R2R 'as quaternary ammonium salts 2NCl, where R = C1-C18 is alkyl, R'-C1-C18 is alkyl, chloralkyl or benzyl at molar ratios of salt: copper of 8-10: 1, the concentration of copper is 0.1-0.5 g / l, and the process is carried out at a temperature of 180-200 ° C with a molar ratio carbon tetrachloride and methylene chloride 1.5-6: 1. ! 2. The method according to claim 1, characterized in that the catalyst is added in 2-4 portions after 90-120 minutes each.
