Реферат:
The influence of the alkali metals Na, K, Rb, and Cs on the catalytic properties of the system V2O5−TiO2 has been studied in the oxidation of o-xylene. When introducing the promoter into the catalyst, and as the alkaline nature of the metals increases, the initial selectivity to partial oxidation products increases. A correlation is observed between the selectivity and the acidity of the surface, which was determined in a model raction of cumene cracking. The most acidic sites of the surface are assumed to be responsible for the destructive oxidation of o-xylene. The rate of oxidation of phthalic anhydride remaines constant when the nature of the additive varied.
