Synthesis of Guaiacol by Catechol and Methanol on Oxide Catalyst

Abstract

Abstract: Complex oxide catalysts of Al₁P_1.30TiaSib(a=0-0.51, b=0-0.90) were prepared by ununiform precipitation method. The vapor phase omethylation of catechol with methanol over the synthesised oxides was studied. The activity and selectivity of these catalysts were greatly dependent on the compositions, the phase structure and surface properties of the catalysts. Among the samples tested, Al₁P_1.30Ti_0.30Si_0.17 gave the highest yield 86 for guaiacol and 92 conversion of catechol at 553 K.
