Abstract
Partial oxidation of p-methoxytoluene to p-methoxy-benzaldehyde was st udied in vapour phase at normal atmospheric pressure over titania, alu mina, titania-alumina, titania-silica, titania-zirconia, titania-silic a-zirconia, silica-zirconia, magnesia, calcia-magnesia supported vanad ia catalysts. Vanadium oxide on basic supports, MgO and CaO-MgO, shows better selectivity towards p-methoxybenzaldehyde with considerable co nversion of p-methoxytoluene at 673 K temperature. However, other acid ic single and mixed oxide supported vanadium oxide catalysts exhibit p oor selectivity at high conversion.
