METHOD FOR REGENERATING WATER-AMMONIA SOLUTION OF CUPROUS ACETATE Russian patent published in 2017 - IPC B01D53/96 C07C7/11

Abstract RU 2626858 C1

FIELD: chemistry.

SUBSTANCE: method for regenerating the absorption water-ammonia solution of cuprous acetate, which was used in the process for the recovery of butadiene-1.3 from the butylene-butadiene fraction, involves filtering the solution through a tauric schist layer and an active coal layer. The mass ratio of the tauric layer to the coal layer is (1.15-7.5):1.

EFFECT: simplifying the regeneration process without reducing the quality of cleaning of the absorption solution.
