| Abstract/Summary |
The course of epoxidation of allyl alcohol with a 30 % hydrogen peroxide over the TS-1 and TS-2 catalysts has been investigated. Two types of solvents, aprotic (acetone) and protic (methanol), were used in the studies. The optimum conditions were established for the epoxidation of allyl alcohol in the presence of acetone and methanol using the TS-1 catalyst. The studies with TS-2 catalyst were performed under the same reaction conditions. The effect of the following process parameters was studied: temperature (20—120ºC), the mole ratio AA—H2O2 ((1—10):1), solvent content (10—80 mass %), catalyst content (0.1—2.0 mass %), and reaction time (1—8 h). It was found that the highest yield of glycidol (64.4 mole % over TS-1, 88.3 mole % over TS-2) was achieved in the presence of methanol independently of the catalyst type. The optimum parameters were the same: temperature 20◦C, the mole ratio of AA—H2O2 = 5, methanol content 80 mass %, reaction time 1 h, but the catalyst content in the reaction mixture was different and amounted to 1 mass % for TS-1 and 0.1 mass % for TS-2.
