Abstract

<p>Addition of 10 - 30 vol.% of C<sub>1</sub> - C<sub>4</sub> alcohols, acetone, acetic acid or acetic anhydride to toluene increases several times the yield of benzaldehyde. The effect of these compounds over V<sub>2</sub>O<sub>5</sub>-K<sub>2</sub>SO<sub>4</sub> catalysts supported on SiO<sub>2</sub> is positive at molar ratio K<sub>2</sub>SO<sub>4</sub> : V<sub>2</sub>O<sub>5</sub> &lt; 0.5. At the ratio K<sub>2</sub>SO<sub>4</sub> : V<sub>2</sub>O<sub>5</sub> ≥ 0.5 the effect is more complex and depends on the conditions used. In the case of V : Ag : K catalyst with the molar ratio 1 : 0.3 : 0.3, added compounds increase the yield of benzaldehyde, except 2-propanol. No effect of these additives was observed over H<sub>9</sub>PV<sub>6</sub>Mo<sub>6</sub>O<sub>40</sub> catalyst supported on SiO<sub>2</sub>.
