Изобретение относится к усовершенствованию процесса очистки монохлоруксусной кислоты (МХУК) от примесей дихлоруксусной кислоты и может быть использовано в технологии получения чистой МХУК путем хлорирования уксусной кислоты. Цель изобретения - снижение расхода катализатора в процессе очистки МХУК методом гидрогенолиза и увеличение селективности процесса. Способ очистки МХУК от дихлоруксусной кислоты проводят каталитическим гидрогенолизом на палладийсодержащих катализаторах в неподвижном слое катализатора в пленочном режиме при нисходящем потоке реагентов при фиктивной скорости подачи сырца МХУК 4,9x10- 2-1,24 м/с.The invention relates to the improvement of the process of purification of monochloroacetic acid (MCAA) from dichloracetic acid impurities and can be used in the technology of obtaining pure MCAA by chlorination of acetic acid. The purpose of the invention is to reduce the consumption of catalyst in the process of cleaning MJUK method of hydrogenolysis and increase the selectivity of the process. The method of purification of MJUK from dichloroacetic acid is carried out by catalytic hydrogenolysis on palladium-containing catalysts in a fixed catalyst bed in film mode with a downward flow of reagents with a fictitious feed rate of MHUK raw material 4.9x10 - 2 -1,24 m / s.
