Abstract
UN PROCESO PARA LA PRODUCCION DE UN POLIOL TAPADO CON OXIDO DE ETILENO, EN DONDE EL POLIOL SE PRODUCE UTILIZANDO UN CATALIZADOR DE CIANURO BIMETALICO, QUE CONSISTE, DESPUES DE LA FORMACION DEL POLIOL, EN LOS PASOS SIGUIENTES: (A) PONER EN CONTACTO UN POLIOL QUE CONTENGA UNO O VARIOS RESIDUOS DEL CATALIZADOR CON UNA CANTIDAD EFECTIVA DE UN OXIDANTE PARA HACER QUE DICHO(S) RESIDUO(S) DEL CATALIZADOR FORMEN RESIDUOS INSOLUBLES QUE SON INSOLUBLES EN EL POLIOL; (B) SEPARAR LOS RESIDUOS INSOLUBLES DEL POLIOL PARA OBTENER UN POLIOL QUE NO CONTENGA ESENCIALMENTE RESIDUOS DEL CATALIZADOR DE CIANURO BIMETALICO; (C) TRATAR DICHO POLIOL SIN RESIDUOS DEL CATALIZADOR DE CIANURO BIMETALICO CON UNA BASE PARA OBTENER UN POLIOL TRATADO CON UNA BASE; (D) PONER EN CONTACTO DICHO POLIOL TRATADO CON UNA BASE CON OXIDO DE ETILENO PARA OBTENER UNA BASE QUE CONTENGA UN POLIOL TAPADO CON OXIDO DE ETILENO, EN DONDE AL MENOS UNA PORCION DE LOS GRUPOS HIDROXILO SECUNDARIOS QUE SE ENCUENTRAN EN DICHO POLIOL SE CONVIERTEN EN GRUPOS HIDROXILO PRIMARIOS Y (E) SEPARAR DICHA BASE DE DICHO POLIOL TAPADO CON OXIDO DE ETILENO PARA OBTENER UN POLIOL TAPADO CON OXIDO DE ETILENO PURIFICADO.
