| titleOfInvention | PROCEDURE TO PURIFY PROCESS VAPORS IN THE PREPARATION OF POLYLACTIDE. |
| abstract | Procedure for the condensation and / or washing of a biodegradable intermolecular cyclic diester in the form of an alpha-hydroxycarboxylic acid of formula II in which R is selected from hydrogen or linear or branched aliphatic moieties having 1 to 6 atoms of carbon, from a mixture of vapors containing the diester of formula II, the alpha-hydroxycarboxylic acid of formula I corresponding to the diester of formula II and water by contacting at least once a stream of a condensing liquid and wash (3) containing an aqueous solution of the alpha-hydroxycarboxylic acid of formula I corresponding to the diester of formula II Formula I with the mixture of vapors, the diester of formula II contained in the mixture of vapors in the condensation liquid being dissolved and washing (3). |
