Abstract

UN METODO MEJORADO PARA LA PURIFICACION DE POLIOL DE POLI(OXIPROPILENO) QUE CONTIENE RESIDUOS DE UN CATALIZADOR DE DMC SEGUN EL CUAL EL POLIOL SE COMBINA CON UNA CANTIDAD DE UN COMPUESTO DE METALES ALCALINOS SUFICIENTE COMO PARA CONVERTIR LOS RESIDUOS DE DCM EN ESPECIES INSOLUBLES, PERO NO LO SUFICIENTE COMO PARA GENERAR GRUPOS ALCOXIDOS DE POLIOL. EL POLIOL SE CALIENTA EN PRESENCIA DE AGUA Y A CONTINUACION SE FILTRA Y SE DEPURA. CON EL METODO NO ES NECESARIO UTILIZAR SILICATO DE MAGNESIO PARA RETIRAR LOS CATALIZADORES DE DMC DE LOS POLIOLES.
