Abstract

Esta invención se refiere a un proceso para la producción de lactida y de polímeros de lactida, sustancialmente purificados, a partir del ácido de lactida o de un éster de ácido láctico, el proceso incluye los pasos de formar un ácido poliláctico crudo, preferiblemente en la presencia de un medio de catalizador en el caso del éster el ácido láctico, para formar un subproducto de la reacción de condensación y ácido poliláctico, y despolimerizar el ácido láctico para formar la lactida cruda, seguido por la purificación subsiguiente de la lactida cruda en un sistema de destilación. Una lactida purificada luego es polimerizada para formar los polímeros de lactida.
