Soybean Oil Epoxide via Reaction-Controlled Phase Transfer Catalysis
Abstract:
The epoxidation reaction of soybean oil with 30% hydrogen peroxide and a heteropolyphosphotungstate salt as reaction-controlled phase transfer catalyst, and 1,2-dichloroethane as the solvent under neutral condition was studied. The optimized reaction conditions were 3%(mass fraction) catalyst, molar ratio of H2O2 and soybean oil 1.2:1, mass ratio of solvent and soybean oil 3.2:1, reaction temperature 70℃, and reaction time 4 h. Under the above mentioned conditions, the epoxy value was higher than 6%, and the iodine value was less than 0.04 g(I)/g. The catalyst was recycled five times without losing catalyst activity, showing excellent reaction controlled phase transfer catalyst property.
