Abstract

PROCEDIMIENTO DE DEPURACION DE OXIDOS DE OLEFINAS. CONSISTE EN DESTILAR UNA MEZCLA QUE CONTIENE EL OXIDO DE OLEFINA EN PRESENCIA DE UNA PEQUEÑA CANTIDAD DE AGUA. SE TOMA EN LA COLUMNA UNA FRACCION DEL LIQUIDO DE CHORREO, SE SOMETE LA FRACCION TOMADA A UNA DECANTACION DE FORMA QUE SE SEPARE UNA FASE ACUOSA QUE SE RECHAZA Y UNA FASE ORGANICA, ENVIANDO LA FASE ORGANICA A LA COLUMNA POR DEBAJO DEL PUNTO DE TOMA. LA SOLUCION ACUOSA INTRODUCIDA CONTIENE DE 0,1 A 20 POR 100 EN PESO DE UN COMPUESTO BASICO TAL COMO HIDROXIDOS, CARBONATOS Y BICARBONATOS DE METALES ALCALINOS Y ALCALINOTERREOS. LA MEZCLA, QUE ADEMAS CONTIENE EL OXIDO DE OLEFINA, CONTIENE AL MENOS UN COMPUESTO ELEGIDO ENTRE LA OLEFINA CORRESPONDIENTE, DISOLVENTES Y LOS ACIDOS CARBOXILICOS DERIVADOS DE LOS PERACIDOS QUE HAN SERVIDO PARA LA FABRICACION DEL OXIDO DE OLEFINA.
