Study on the Liquid Phase Reaction of Ozone with Ethylbenzene and Its Derivatives

This work deals with the investigation of the reactions of ethylbenzene and its derivatives with ozone in a solution of glacial acetic acid. The products and kinetic features of oxidation were studied, the kinetic parameters of the reactions were found, and the mechanism of ozonation in the liquid phase was proposed. The influence of deactivating substituents (-Br, -NO2) in the aromatic ring on the selectivity of the side chain oxidation of the substrate was established.

IMPROVEMENT OF HOMOGENEOUS CATALYTIC PROCESS OF OXIDATION OF ALKYLAROMATIC COMPOUNDS BY COMBINATION OF BINARY CATALYTIC SYSTEMS AND ULTRASOUND TREATMENT

Article is devoted to research of impact of combined use of catalytic systems based on
industrial oxidation catalysts and surface-active compounds of different nature (ion- and noniongenic)
with ultrasonic treat ment of reaction mixture at alkylaromatic compounds liquidphase
oxidation process. Obtained results showed that combined use of catalytic system and
ultrasound has impact on ethylbenzene oxidation. Created catalytic systems not only increase
productivity of reaction volume (for aim products), but also allow to shift process selectivity
