Procedure

Limonene (1.36 g, 10 mmol) was dissolved in butyl acetate (25 ml), and a composition containing sodium percarbonate (6.0 g, 38.1 mmol) and acetic anhydride (10.2 g, 100 mmol) was added thereto. The mixture was stirred at 60° C. After 12 hours, the reaction solution was washed with water to thereby completely remove acetic acid and sodium acetate, which were generated as by-products, and the remaining H2O2. Butyl acetate was distilled off from the organic phase by distillation, and as a result, 1.63 g (97% yields) of limonene diepoxide with a GC purity of 97% were obtained.
