Abstract
Un proceso mediante el cual se obtiene una mezcla de ácido carboxílico/diol adecuada como material de partida para una producción de poliéster a partir de una solución de ácido carboxílico decolorada sin aislamiento de un sólido de ácido carboxílico. Más específicamente, se proporciona un proceso mediante el cual se obtiene una mezcla de ácido tereftático/etilén glicol adecuada como material de partida para una producción de poliéster a partir de una solución de ácido tereftálico decolorada sin aislamiento de un sólido de ácido tereftálico. Reivindicación 1: Un proceso para la producción de una mezcla de ácido carboxílico/diol, comprendiendo dicho proceso la adición de un diol a una solución de ácido carboxílico decolorada en una zona de reactor de esterificación para eliminar una porción del agua para formar dicha mezcla de ácido carboxílico/diol; reaccionando dichos ácido carboxílico y diol subsecuentemente en dicha zona de esterificación para formar una corriente de éster de hidroxialquilo. Reivindicación 35: Un proceso para la fabricación de una corriente de éster de hidroxialquilo que comprende adicionar un diol a una lechada acuosa de ácido tereftálico para formar una mezcla den ácido tereftálico/diol que comprende ácido tereftálico, diol y agua; en la cual la cantidad de ácido tereftálico es de más de 40% en peso; estando la relación de masa de agua respecto del diol en el orden de 0,01: 1 a 1,5 : 1.
