Abstract:
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.
