| Abstract: | The phase-transfer epoxidation of soybean oil with 30% hydrogen peroxide catalyzed by tungsten-based polyoxometallate complex without solvent and with petroleum ether as the solvent was studied and the effects of solvent, reaction time and catalysts on product were studied. The result showed that the epoxide number amounted to 6.4% and the iodine value was 4.4 mg/100 mg with petroleum ether as the solvent,CWP as catalyst react 6 h at 60℃. |
| Keywords: | soybean oil epoxidation tungsten-based polyoxometallate complex hydrogen peroxide |
