Abstract
PROCEDIMIENTO PARA LA PURIFICACION DE UN ADUCTO DE OXIDO DE ALQUILENO FABRICADO CON CATALIZADORES METALICOS HALOGENADOS Y QUE CONTIENE COMO IMPUREZAS HALOGENOS Y METALES. EL ADUCTO SE TRATA CON UN EXCESO DE COMPUESTOS ALCALINOS METALICOS Y LA MEZCLA ALCALINA OBTENIDA SE AJUSTA CON UN ACIDO A UN VALOR PH MAXIMO DE 7. LA MEZCLA DE PRODUCTOS DEBE CONTENER UN 0,1 % EN PESO DE AGUA, REFERIDO AL PESO DEL PRODUCTO. DE ESTA MEZCLA SE SEPARAN EL AGUA Y LOS DEMAS DISOLVENTES. LAS SALES INSOLUBLES EN EL ADUCTO SE PRECIPITAN EN FORMA CRISTALINA.
