摘要：
A METHOD OF PREPARING A CATALYST OF VANADIUM-TITANIUM OXIDES FOR VAPOR-PHASE OXIDATION AND OXIDIZING AMMONOLYSIS OF AROMATIC AND HETEROCYCLIC COMPOUNDS COMPRISING PREPARING A POWDERY MIXTURE OF VANADIUM PENTOXIDE AND TITANIUM DIOXIDE WITH THE MOLE RATIO OF 1:0.6-32, RESPECTIVELY. THE AFORESAID MIXTURE IS PRESSES INTO TABLETS AND THEN EXPOSED TO HEAT TREATMENT IN AIR AT A TEMPERATURE OF FROM 650* C. TO 1000* C. SAID METHOD IS TECHNOLOGICALLY SIMPLE AND MAKES IT POSSIBLE TO OBTAIN A CATALYST FEATURING HIGH ACTIVITY AND SELECTIVELY AS WELL AS HIGH MECHANICAL STRENGTH AND THERMAL STABILITY.
