CATALITIC OXIDATION OF POLYCHLORO-BENZENES AND TOLUENES

Catalytic systems based on vanadium, molibdenium, phosphorous, stibium, cobalt oxides were synthesized and put in practice for the disposal of polychloro-benzenes and toluenes. By the investigations of the systems on modern physico-chemical XPS, IRS, Derivatograph, apparatuses phase formation on catalysts, surface and porous parameters, nature of active centers were determined. It is established that active components condition of obtained catalyst influences on phase formation process. The activity of attained catalysts samples were investigated in the oxidation reactions of polychloro-benzenes and toluenes at the temperature 673–753 K; 0.1–1.1 seccontact time; 1:5–1:25 molar ratios of chloric compounds to oxygen. With this, at rendering harmless of these compounds attained maleic anhydride and its derivatives have been got
