Abstract
SE PRESENTA UN PROCESO PARA PURIFICAR POLIOLES DE POLIETER PREPARADOS USANDO UN DOBLE CATALIZADOR DE CIANURO DE METAL (DMC). EL PROCESO COMPRENDE LA COMBINACION DE UNA MEZCLA DEL POLIOL Y UN ALCOHOL ALIFATICO C1-C6 CON UNA CANTIDAD DE UN AGENTE QUELANTE EFECTIVA PARA FORMAR UN COMPLEJO INSOLUBLE CON EL CATALIZADOR. POSTERIORMENTE SE FIJA LA MEZCLA DE POLIOL PARA ELIMINAR EL PROCESO INSOLUBLE. EL PROCESO, QUE REQUIERE QUE EL POLIOL Y EL ALCOHOL ESTEN PRESENTES EN UNA PROPORCION DE PESO RELATIVA DE ENTRE 1:1 Y 100:1, ES EFECTIVO PARA ELIMINAR RESIDUOS DE DMC Y CUALQUIER CATION INTRODUCIDO CON EL AGENTE QUELANTE.
