Abstract
AbstractThe influence of the technological parameters on the epoxidation of allyl alcohol by a 30 wt% hydrogen peroxide in the medium of methanol over the Ti–BETA catalyst in the direction of glycidol has been presented. The experimental conditions were established on the basis of preliminary experiments and through the applications of statistical experimental design methods (rotatable uniform design). The results of the particular experiments were described by the following functions: the yield of glycidol in relation to allyl alcohol introduced into the reactor, the selectivity of transformation to glycidol in relation to allyl alcohol and hydrogen peroxide reacted, and the degree of conversion of allyl alcohol and H2O2. The optimal values of each function were established. The courses of functions corresponding to the parameters were plotted in the system of two variable parameters. The optimum parameters of the epoxidation process were established after the analysis of the layer drawings. The obtained results were confirmed by a series of verifying syntheses.
