Abstract
A process for hydrolyzing alkylene oxides to alkylene glycols in the presence of CO2, and a basic non- halogen containing catalyst. The reaction is effected under a carbon dioxide pressure of less than about 350 psig and a reaction temperature between about 85 DEG C and 400 DEG C. The reaction is preferably effected in the presence of an organic solvent.
