摘要：

Phase-transfer catalyzed biphasic epoxidation of a series of fats and oils with ethylmethyldioxirane in 2-butanone was conducted. The series of glycerides studied varied from monounsaturated (olive) to highly polyunsaturated (flaxseed) oils. Best conversions for polyunsaturate-containing oils were obtained with a molar ratio of 2.5:1 (oxidant/oil) with two-step addition of oxidant. Conversion to epoxides was monitored by gas-liquid chromatography, and oxirane content was determined by titration. The effect of phase-transfer catalyst or solvent used for the epoxidation reaction also was investigated.
