Title
Optimization of the reaction parameters of epoxidation of allyl alcohol with hydrogen peroxide over TS-2 catalyst
Abstract

The influence of technological parameters on the epoxidation of allyl alcohol to glycidol with 30 wt.% hydrogen peroxide was presented. The reaction was performed in a autoclave at autogenic pressure and in methanol medium (protic solvent). The influence of the following parameters was investigated: temperature (15–90 °C), the molar ratio AA/H2O2 (0.5–5), methanol concentration in reaction mixture (5–90 wt.%), TS-2 concentration in reaction mixture (0.1–2.0 wt.%) and the reaction time (15–120 min). The optimum conditions were established by the mathematical method of design of experiments (rotatable-uniform design). The received results were described by the following mathematical functions: selectivity of transformation to glycidol in relation to consumed allyl alcohol and hydrogen peroxide and conversion of allyl alcohol and H2O2. The courses of functions for appropriate parameters were plotted in the system of two variable parameters. The optimum parameters of the epoxidation process were established based on the analyses of the layer drawings.
