IMPROVEMENTS IN OR RELATING TO THE ELECTROLYTIC REDUCTION OF 2,4 DINITROTOLUENE TO 2,4 DINITROTOLUENE TO 2,4 DIAMI NO TOLUENE

摘要

A process which comprises in electrolytically reducing a suspension of 2, 4 dinitro toluene to 2, 4 diamino toluene in a supporting electrolyte of mineral acid preferably sulphuric acid upto a concentration of 25% (V/V) using stationary or rotating electrode of copper and employing titanous or titanic sulphate as addition agent preferably upto a concentration of 10 g TiOSUB2/SUB per litre of catholyte and using current densities ranging from 0.25 A/dmSUP2/SUP and temperature 70-80degrees C.
