実験手順

A mechanically stirred mixture of 1 kg. (7.3 mol.) of d-limonene (7.3 mol.) and sodium carbonate (310.6 g) was cooled to 0°-10° C., and treated with 1.61 kg. (9.1 mol.) 40% peracetic acid by dropwise addition. After the addition was complete, the reaction mixture was stirred for another 45 min., washed with ice water, sodium carbonate, and brine. The oil was dried over magnesium sulfate, and distilled to give recovered limonene (30 g), the cis-epoxide (257 g) and trans-epoxide (296 g), and diepoxide (82 g).
