Descripción general

la 3,6-dimetil-1,4-dioxano-2,5-diona (o rac-lactida), es la mezcla racémica 50:50 de D- y L-Lactida. La rac-lactida es una lactona derivada del ácido láctico que ha despertado un gran interés en el mundo académico y en las aplicaciones comerciales, ya que se obtiene a partir de abundantes recursos renovables. La rac-lactida puede polimerizarse mediante polimerización de apertura en anillo, utilizando diversos catalizadores metálicos u organocatalizadores, para obtener poli(D,L-lactida). Aunque el polímero resultante suele ser amorfo, el uso de catalizadores estereoespecíficos puede dar lugar a PLA heterotáctico, que presenta cierto grado de cristalinidad.

Aplicación

La DL-Lactida se utiliza para producir el éster 1-(1-feniletoxicarbonil)-etil del ácido 2-hidroxipropiónico. Actúa como una importante materia prima y un intermediario utilizado en síntesis orgánica, productos farmacéuticos, agroquímicos y colorantes. Interviene en la alcohólisis enzimática para producir tanto alquil (R)-lactatos como alquil (S,S)-lactilactatos.
