Abstract

In this work we report on the epoxidation of soybean oil by the trichloroacetonitrile -CH₂Cl₂/H₂O₂ byphasic system. The reaction was carried out at room temperature and, most importantly, in non acid conditions which prevent the opening of the oxirane ring. The epoxidized soybean oil was characterized by infrared, ¹H and ¹³C NMR. A maximum conversion of 81 % was achieved in two hours with 86% of selectivity in epoxy groups
