Abstract:
The epoxidation reaction of methyl abietate with 30% H2O2 as oxidant catalyzed by tetrabutylammonium divacant lacunary silicotungsate in acetonitrile solvent was studied. UV, IR, GC and GC/MS spectra of the oxidation products showed that monoepoxide and diepoxide of methyl abietate were mainly formed by the mild selective oxidation of methyl abietate with H2O2. The influences of catalyst and oxidant dosage, temperature, reaction time on oxidation conversion and selectivity were investigated by monitoring the course of reaction. The optimum conditions were investigated as follow: methyl abietate 5 mmol, catalyst 10 μmol,30% H2O2 0.45 mL, acetonitrile 5 mL, reaction temperature 50℃ and reaction time 10 h. The oxidation conversion of methyl abietate and the epoxidation selectivity were 98% and 62%, respectively under that conditions.
