Title
(EN) PROCESS FOR PREPARING GLYCOLIDE
(FR) PROCÉDÉ DE PRÉPARATION DE GLYCOLIDE
Abstract
(EN)
According to the present invention a process is provided for producing glycolide which comprises contacting glycolaldehyde dimer with an oxidizing agent to produce a glycolide product.Preferably, the process is carried out in an aprotic environment, such as in a reaction mixture comprising the glycolaldehyde dimer, the oxidizing agent, the glycolide product and an aprotic solvent.
(FR)
La présente invention concerne un procédé de production de glycolide comprenant la mise en contact d'un dimère de glycolaldéhyde avec un agent oxydant pour produire un produit de glycolide, le procédé est mis en œuvre, de préférence dans un environnement aprotique, tel que dans un mélange réactionnel comprenant le dimère de glycolaldéhyde, l'agent oxydant, un produit glycolide et un solvant aprotique.
