Abstract

Se describe un proceso mejorado para reciclar diol sin agotar separado de un proceso de manufactura de poliéster en donde el diol es capturado, hidrogenado y reciclado de tal manera que el producto de poliéster final tiene color mejorado con respecto a los poliésteres producidos utilizando otros dioles reciclados. Reivindicación 1: Un proceso para la fabricación de poliéster, caracterizado porque comprende: a) formar una pasta aguada ó suspensión de un diol seleccionado del grupo que consiste de etandiol, propandiol y butandiol con un ácido dicarboxílico seleccionado del grupo que consiste de ácido tereftálico y ácido isoftálico; b) esterificar la suspensión ó pasta aguada para formar un oligómero; c) polimerizar el oligómero; capturar el diol no agotado como una corriente de reciclado; hidrogenar la corriente de reciclado que contiene el diol son agotar en presencia de hidrógeno y por lo menos un catalizador de hidrogenación y f) devolver el diol hidrogenado a la suspensión.
