J. Miki et al., SELECTIVE OXIDATION OF TOLUENE TO BENZOIC-ACID CATALYZED BY MODIFIED VANADIUM-OXIDES, Applied catalysis. A, General, 137(1), 1996, pp. 93-104
A variety of oxides were examined as additives to a V2O5/TiO2 catalyst
in order to enhance the catalytic performance for the vapor phase oxi
dation of toluene to benzoic acid. It was found that the modification
with SeO2, TeO2 or Sb2O3 greatly promoted the title reaction leading t
o improved catalyst performance in terms of toluene conversion and ben
zoic acid selectivity. The effect of reaction temperature, O-2/toluene
ratio, steam/toluene ratio and durability were also investigated in o
rder to reveal the catalytic features of the modified catalyst systems
