Abstract

UN METODO PARA ELIMINAR DICHO CATALIZADOR DE POLIOLES DE POLIESTER USA UNOS COMPUESTOS DE METAL ALCALI Y FOSFOROS PARA PRECIPITAR EL CATALIZADOR RESIDUAL QUE PUEDE ENTONCES SER ELIMINADO POR FILTRACION. EN OTRA EXPRESION UN POLIOL OXIDO DE PROPILENO ES TRATADO CON DISPERSION METALICA DEL SODIO CORONADO CON OXIDO DE ETILENO, TRATADO CON SILICATO DE MAGNESIO, Y ENTONCES EL FILTRADO PARA ELIMINAR AL MENOS UNA PARTE DEL CATALIZADOR. LA ELIMINACION TOTAL DEL CATALIZADOR ES CONSEGUIDA AL TRATAR EL POLIOL CON ACIDO FOSFOROSO O HIPOFOSFOROSO Y PRECIPITAR EL RESIDUO RESTANTA NEUTALIZANDO EL EXCESO DE ACIDO CON SILICATO DE MAGNESIO Y FILTRANDOLO.
