Epoxidation of allyl alcohol over mesoporous Ti-MCM-41 catalyst.
Epoxidation of allyl alcohol with 30 wt% hydrogen peroxide over Ti-MCM-41 catalyst under atmospheric pressure and in the presence of methanol as a solvent has been studied. The influence of the following parameters: temperature (20-60 degrees C), the molar ratio of AA/H(2)O(2) (0.5-5), methanol concentration (5-90 wt%), catalyst concentration (0.1-5.0 wt%) and reaction time (5-180 min) has been investigated. The process has been described by the following functions: the selectivity of transformation to glycidol in relation to allyl alcohol consumed, conversions of the substrates and selectivity of transformation to organic compounds in relation to hydrogen peroxide consumed. The technological parameters, at which the functions describing the process take the optimum values, have been established.
