METHOD FOR HYDRODECHLORINATION OF STARTING MATERIAL CONTAINING DICHLOROACETIC ACID Russian patent published in 2020 - IPC C07C51/377

Abstract RU 2724102 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method for catalytic hydrodechlorination of dichloroacetic acid, in which gaseous hydrogen is brought into contact with a liquid starting material, containing dichloroacetic acid and monochloroacetic acid to form a product stream comprising monochloroacetic acid and a waste gas stream containing hydrogen chloride and hydrogen, and wherein product stream is brought into contact with gaseous nitrogen in order to remove gaseous hydrogen present in product stream.

EFFECT: technical result is obtaining a cleaner product.
