Abstract

UN PROCESO PARA REDUCIR LA CANTIDAD DE POLIETERES DE PROPENILO EN POLIETERES HIDROXI-FUNCIONALES QUE COMPRENDE (1) PONER EN CONTACTO UN POLIETER HIDROXI-FUNCIONAL NEUTRO, QUE CONTIENE UN POLIETER DE PROPENILO Y AGUA, Y UN CATALIZADOR ACIDO SOLUBLE EN EL POLIETER HIDROXI-FUNCIONAL BAJO CONDICIONES DE REACCION SUFICIENTES PARA CONVERTIR POR LO MENOS UNA PARTE DEL POLIETER DE PROPENILO EN PROPIONALDEHIDO; (2) PONER EN CONTACTO EL PRODUCTO DE LA ETAPA (1) Y UN COMPUESTO EPOXI PARA LIMPIAR SUSTANCIALMENTE EL CATALIZADOR ACIDO; Y (3) DECAPAR EL PRODUCTO DE LA ETAPA (2) PARA ELIMINAR SUSTANCIALMENTE EL COMPUESTO EPOXI Y EL PROPIONALDEHIDO. LOS POLIETERES HIDROXI-FUNCIONALES RESULTANTES CONTIENEN CANTIDADES REDUCIDAS DE POLIETERES DE PROPENILO Y PUEDEN POR LO TANTO UTILIZARSE PARA PREPARAR ESPUMAS DE POLIMETANO CON UNA TENDENCIA REDUCIDA A LA DECOLORACION.
