Abstract
Procedimiento para la obtención de dicarboxilatos de propilenglicol en la obtención de óxido propilénico bajo reacción de propileno con una solución de un ácido percarboxílico en un disolvente inerte, cuyo punto de ebullición es inferior al del ácido carboxílico, que corresponde al ácido percarboxílico empleado como medio de epoxidación, y superior al del óxido propilénico, separación destilativa de la mezcla de reacción conteniendo esencialmente óxido propilénico, el ácido carboxílico correspondiente al ácido percarboxílico empleado como agente de epoxidación y uno o varios de los productos secundarios propilenglicol, monocarboxilato de propilenglicol y dicarboxilato de propilenglicol, así como propileno y el disolvente orgánico, en una parte que contiene óxido propilénico y propileno, y una parte conteniendo el ácido carboxílico, los mencionados productos secundarios y el disolvente orgánico, y ulterior descomposición de estas partes en los distintos componentes por destilación.
