Abstract
Epoxidation of allyl alcohol with 30% hydrogen peroxide over Ti-Beta and Ti-MCM-41 catalysts has been studied under atmospheric pressure in the presence of methanol as a solvent. The influence of the following parameters: temperature (20-60˚C), AA/H2O2 molar ratio (0.5:1-5:1), methanol concentration (5-90 wt%), catalyst concentration (0.1-9.0 wt%) and reaction time (1-180 min) has been investigated. The process has been described by the following functions: the selectivity of transformation to glycidol, glycerine, allyl-glycidyl ether and bis(allyl) ether in relation to consumed allyl alcohol, conversions of the substrates and selectivity of transformation to organic compounds in relation to consumed hydrogen peroxide. The technological parameters, at which the functions describing the process take the optimum values, have been established.
