Galstyan A. The reactions of nitrotoluenes and its oxycompound derivatives with ozone in solution of acetic acid

The research of the process of the ozonation of nitrotoluenes in acetic acid has show that introduction toluene molecule of electron-acceptor substitute into benene ring though increases the stability of aromatic zing to attack of ozone, but the reaction of its destructive oxidation remains dominating. Introduction cobalt diacetate into nitrotoluene-ozone-acetic acid system permits practically to stop ozonation of aromatic ring and direct the reaction into oxidation side on methyl group with producing corresponding nitrobenzoic acid. Usind cobalt-bromide catalyst promotes the increasing selective oxidation rate and decreasing catalyst concentration in the system
