The epoxidation of diallyl ether to allyl-glycidyl ether over the TS-1 catalyst

Abstract

Research on the epoxidation of diallyl ether (DAE) to allyl-glycidyl ether with 30 wt% hydrogen peroxide and in the presence of the TS-1 catalyst is presented. In this work, methanol was tested as the solvent. The influence of the following parameters was studied: the temperature 25-80°C, the molar ratio of DAE/H 2 O 2 0.25:1-5:1, the solvent concentration 10-90 wt%, the content of the TS-1 catalyst 1-9 wt% and the reaction time 15-240 min. Because the effective conversion of hydrogen peroxide was relatively low during the studies, after establishing the most beneficial conditions for the epoxidation of DAE, the influence of an addition of the chosen inorganic salt-KH 2 PO 4 on the effective conversion of hydrogen peroxide and other functions characterized this process was also tested.

The Studies on α-Pinene Oxidation over the TS-1. The Influence of the Temperature, Reaction Time, Titanium and Catalyst Content

“…Currently, the TS-1 catalyst is one of the most frequently used titanium-silicate catalysts in catalytic processes (it is also used in industrial processes). It is especially used in oxidation processes with the use of hydrogen peroxide as an oxidant (e.g., epoxidation of allyl alcohol [10,11], allyl chloride [12][13][14], limonene [15], diallyl ether [16,17], cyclohexene [18], or phenol hydroxylation [19,20]. Based on the previous applications of the TS-1 catalyst we decided to select this catalyst for research on the oxidation of α-pinene.…”
