METHOD FOR OBTAINING 4-CHLORO-2-AMINOPHENOL Russian patent published in 2023 - IPC C07C213/02 C07C215/76 

Abstract RU 2803889 C1

FIELD: chemistry.

SUBSTANCE: method for producing 4-chloro-2-aminophenol by electrochemical reduction of 4-chloro-2-nitrophenol. The reduction is carried out in an ammonia buffer solution with a pH of 9.5-10.4 on a stainless steel cathode of the X18H10T brand at a current density of 10.0-15.0 A/dm2 and a temperature of 60-70°C.

EFFECT: increasing the yield of 4-chloro-2-aminophenol by substance up to 95.0-96.0%.
