Abstract

Un procedimiento para preparar un poliester basado en 1,3-propanodiol que comprende poner en contacto una corriente acuosa que contiene un subproductode acroleína con una base durante un tiempo efectivo para reducir el contenido de acroleína de lacorriente acuosa. En una forma de realización específica, unprocedimiento de preparación de poli(propileno tereftalato) comprende los pasos de: (a) poner en contacto, 1,3-prapanodiol y ácido tereftálico a temperaturaelevada para producir una mezclade producto de reacción que comprende un poli(propileno tereftalato) y una solución acuosa que comprende acroleína; (b)retirar una porción importante de la solución acuosa de dicha mezcla de productos de reacción; (c) agregar una cantidad suficiente de una base a lasolución acuosa para formar una solución básica que tiene un pH mayor que 7,5 y mantener la solución básica durante un tiempo efectivo para disminuir elcontenido de acroleína de la misma;(d) opcionalmente, diluir la solución básica con agua; y (e)opcionalmente, tratar biológicamente la solución básica diluida.El procedimiento de la invención provee una corriente de subproducto de poliéster que contiene niveles reducidos de acroleína.
