Abstract

The effects of reaction conditions and concentration of the heteropoly acid H4PMo11VO40 supported onto ShAS-2 bead aluminosilicate on the conversion of toluene into benzoic acid in the partial oxidation of toluene by atmospheric oxygen were studied. The results demonstrated that the conversion of toluene was an extremal function of temperature, space velocity (v), and toluene concentration (C 0) in the initial air mixture. An increase in the heteropoly acid concentration from 2 to 30% increased the conversion of toluene into benzoic acid in the partial oxidation of toluene from 1.5 to 12.6% at optimum process parameters: T = 300°C, v = 2000 h-1, and C 0 = 13.72 g/m3.
