The process parameters such as temperature and flow rate influence the product distribution. The P2O5, B2O3 and Na2O when used as dopant on V2O5-MoO3 catalyst showed marked influence on activity and selectivity. An acidic catalyst like V2O5-MoO3-P2O5 favours formation of benzoic acid while a basic catalyst like V2O5-MoO3-Na2O favours formation of benzaldehyde. The addition of Na2O into V2O5-MoO3 binary oxides formed new phases (NaVMoO6 and Na2V2Mo3O15), which increased Arrhenius activation energy from 18.24 to 31.35 kcal mol(-1).</p>10aacetophenone10aactivity10abenzoic acid10acarbon oxides10aoxidation of acetophenone10aselectivity1 aChumbhale, Vilas, R.1 aParadhy, S., A.1 aAnilkumar, Mettu1 aKadam, S., T.1 aBokade, Vijay, V.  uhttps://library.ncl.res.in/content/vapour-phase-oxidation-acetophenone-benzoic-acid-over-binary-oxides-v-and-mo-0
