SYNTHESIS OF P HYDROXYBENZALDEHYDE BY THE CATALYTIC OXIDATION OF P CRESOL

The liquid phase heterogeneous catalytic oxidation of p cresol to p hydroxybenzaldehyde by air is studied using cobaltosic oxide carried on resin as catalyst.In this paper,the suitable carriers of catalyst are selected and the optimal reactive condition is determined.The prepared catalyst gives a good catalytic activity and satisfactory useful life.The conversion of p cresol and the selectivity of the product,p hydroxybenzaldehyde,under the optimal reactive condition,were 90% and 91% respectively.By the research on the kinetics of the reaction,the reaction rate equation is established and the activation energy is obtained.
