Catalytic conversion of p-chloro substituted toluene has carried out in the presence of oxovanadium catalysts. The activities of synthesized variety catalytic systems based on V, P, Mo, Sb oxides were determined in the oxidation reaction of psubstituted toluene. It was shown, the appropriate optimum reaction condition for the activity and selectivity for received catalysts was designated (temperature 603-753 K; contact time 0.6-0.8 sec-1; mole ratio of p-substituted toluene to O2 (XY:O2)=1:10-1:25) and under this condition the conversion of p-chlorotoluene was 80-90%. Meanwhile, besides helping to solve ecological problem with the neutralization of ecological harmful substance, also received very important raw materials (benzaldehydes, maleic anhydride (MA) and their chloro analogues) for petrochemical synthesis.
