Abstract

UN PROCESO PARA EL CAMBIO IONICO DE POLIOLS POR ELIMINACION DE CATALIZADORES DONDE DICHO CATALIZADOR ES UN ALKALI HIDROXIDO O UN ALKOXIDO COMPRENDIENDO LOS SIGUIENTES PASOS : A) MEZCLAR LA MOLECULA DE POLIETER QUE TIENE UN PESO MOLECULAR DE 500-10.000 CON AGUA, V) COMBINAR EN EL PRODUCTO DE A) UNA CANTIDAD SUFICIENTE DE UN ALCOHOL ALFATICO INFERIOR PARA ROPER LA EMULSION FORMADA EN EL PESO (A).C) PASAR EL PRODUCTO DEL PASO (B) A TRAVES DE UNA RESINA PERMUTADORAS DE CATIONES MACROPOROSAS PARA OBTENER UNA MOLECULA DE POLIETER PURIFICADA, METANOL, Y AGUA. EL PRODUCTO DE (C) PUEDE SER ADEMAS SOMETIDO A UNA DEPURACION PARA PRODUCIR LOS POLIOLES DE POLIETER PURIFICADOS.
