Abstract

Catalytic properties that mesoporous amorphous titanosilicate catalysts differing in physicochemical characteristics exhibit in cyclohexene oxidation with hydrogen peroxide to a mixture consisting mainly of alcohol and ketone were studied. The cyclohexene conversion and selectivity of formation of oxidation products depend both on the physicochemical properties of the titanosilicates studied (nature of active sites, porosity, etc.) and on the reaction conditions. The total selectivity with respect to the enol + enone fraction of 94% at the maximal cyclohexene conversion of 55% was reached in the presence of TSMa titanosilicate (Si/Ti = 40).
