The activities of vanadium oxide catalysts with   P, Mo, Sb additions drawn on  SiO2 and Al2O3 in the reaction of oxidation of n-chlorotoluene has been iinvestigated. It is shown that the catalytiсal systems V–Mo–Sb–O/Al2O3 possess higher activities. Effect of the catalyst components activities on the reaction of oxidation mono-chlorotoluene has been determined. At ratio of the active components V:P=1:2–1:3 the catalytical system V–Mo–O/SiO2 display high activity at conversion of 2-chloro­toluenes  equal to 85% , the yield of the basic product of oxidation MCMA makes  up 24–28%

Keywords : catalytical oxidation, 2-chlorotoluene, catalysts – vanadium oxide, molybdenum oxide, phosphor, maleic anhydride, chloro-maleic anhydrides
