Abstract
Un procedimiento de despolimerización y purificación, que comprende: (a) poner en contacto un poliéster contaminado con una cantidad de un glicol para proporcionar una relación molar entre unidades totales de glicol y unidades totales de ácido dicarboxílico mayor que 1 a 5, a una temperatura entre 150 a 300°C y una presión absoluta de 0, 49 a 2, 96 atmósferas en un reactor con agitación durante un tiempo suficiente para producir, en el reactor, una capa superior que comprende un contaminante de densidad relativamente baja flotando por encima de una capa inferior que comprende un oligómero despolimerizado de dicho poliéster; y (b) separar dicha capa superior de dicha capa inferior retirando dicha capa superior del reactor en una primera corriente y retirando dicha capa inferior del reactor en una segunda corriente.
