Abstract

Chromium-substituted aluminophosphates were synthesized and characterized. Chromium-aluminophosphoates (CrAPO-5 and CrAPO-11) catalyze the oxidn. of ethylbenzene, p-ethyltoluene, n-propylbenzene, n-butylbenzene, diphenylmethane, p-ethylanisole, and primary, secondary benzylic alcs. to the corresponding ketones or acids with TBHP at 80-100 DegC. The main parameters affecting reaction rates are competitive adsorption and diffusion. The activity of used CrAPO-5 is completely recovered by recalcination at 500 DegC. Oxidn. of 4-methoxybenzyl alc. gave 4-methoxybenzoic acid (100% conversion of reactant; 87% selectivity toward product).
