Abstract

A 5-30% solution of MnSO4 or MnCl2 is reacted at a maintained pH of 0.5-3.0 with chlorine gas, the reaction being stopped before permanganate formation starts. The reaction is pref. carried out in the presence of microscopic carbon to give MnO2 particles with included carbon. The carbon pref. has a chain structure ('Shawinigan carbon black'). Reaction temp. 25-80 C, added carbon 1.5-10 wt.% on final product. Neutralising reagent is pref. Mg(OH)2, for MnSO4 mixtures, or Ca(OH)2 for MuCl2 mixtures.
