Abstract

Reaction of ozone with ethylbenzene in acetic acid is studied. It is shown that oxidation of ethylbenzene by ozone develops in two directions: on double bonds of an aromatic ring with the formation of  aliphatic peroxides and ethyl group with the formation of phenyl methyl carbinol and acetophenone. It is established that the main products of reaction are peroxide compounds - products of destruction of the aromatic ring (60% ) and, to a lesser extent, oxidation products on a side chain - acetophenone (25 %) and phenyl methyl carbinol (10 %). The constants of the rates of ozone reaction with ethylbenzene at various temperatures are defined, and the reaction mechanism, which explains the obtained experimental data is proposed.

During the research, the concentration of ethylbenzene and products of its transformation in solution was determined by a method of gas-liquid chromatography on the chromatograph with flame ionization detector. The content of peroxide compounds was determined by iodometric titration. The constants of the rate of ozone reaction with ethylbenzene were calculated by the method described in the paper [2].
