摘要：
It has been established that at high temperatures (above 450 degrees C) the V2O5-ZrO2 catalyst exhibits a higher selectivity in the oxidation of o-xylene to phthalic anhydride than does the conventional V2O5-TiO2(a) catalyst. The catalyst selectivity is found to increase with respect to partial oxidation of o-xylene, the valuable by-product maleic anhydride being obtained. Studies by different physicochemical methods have shown that V2O5-ZrO2 undergoes no significant phase and structural changes under high-temperature conditions.
