Litvinova I. The reaction of toluene and its oxycompound derivatives with ozone in solution of acetic acid

For the first time the complex study of the oxidation reaction of toluene and its oxycompound derivatives with ozone in solution of acetic acid was conducted. It has been shown that the oxidation of toluene occurs in the complex mechanical conditions where the aromatic system is mostly damaged. It was discovered that liquidphase ozonization of toluene in acetic acid is a complex chain-radical process, in which methylbenzene oxidizes on the non-chain route, but ozone is spent into two routes: into the non-chain route at the initiation step and into the chain route - with the ozo-nolysis products of the aromatic ring. The kinetics of oxidation of toluene by ozone content gases in presence of metalcatalysts with the changing valency and bro-mides has been worked out. The mechanism of catalysis has been observed, it was shown that in catalytic conditions the ozonolysis of the aromatic ring is greatly prevented, the selective oxidation of a-C-H-bond of the methyl group fecomes noticeable. The mechanism obta ined for the rate of the reaction is in compliance with the scheme of toluene oxidation. New methods of benzoic acid syntheses have been worked out.The results of the work are of great importance for the preparation syntheses of benzoic acid and in the further reactions of ozone with aromatic compounds.
