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
towards creation of desired product.
