IMPROVEMENTS IN OR RELATING TO THE ELECTROLYTIC REDUCTION OF P-NITROPHENOL TO P-AMINOPHENOL

摘要

A process for the manufacture of -aminophenol which comprises in electrolytically reducing a suspension of p-nitrophenol to p-aminophenol in a supporting electrolyte of mineral acid preferably sulphuric acid upto a concentration of 10% V/V using stationary or rotating electrode of copper, and employing a current density upto 20 amp/dm2 and temperature between 50 and 60C.
