RESUMENReactividad del sistema bifásico tricloroacetonitriloCH2Cl2/H2O2 en la epoxidación del aceite de soja.En el presente trabajo informamos sobre la epoxidación de aceite de soja mediante el sistema bifásico tricloroacetonitriloCH2Cl2/H2O2. La reacción fue realizada bajo condiciones de temperatura ambiente y, lo más importante, en condición no ácida, lo que evita la apertura del anillo oxirano. El aceite de soja fue caracterizado por infrarrojo y RMN de 1 H y 13 C. En dos horas se alcanzó una conversión máxima del 81% obteniéndose una selectividad del 86% en grupos epóxidos.PALABRAS-CLAVE: Aceite de soja -Epoxidación -NitriloPeróxido de hidrógeno -Sistema bifásico.
SUMMARYReactivity of the biphasic trichloroacetonitrileCH2Cl2/H2O2 system in the epoxidation of soybean oil.In this work we report on the epoxidation of soybean oil by the trichloroacetonitrile-CH2Cl2/H2O2 biphasic 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, 1 H and 13 C NMR. A maximum conversion of 81% was achieved in two hours with 86% of selectivity in epoxy groups.
