ABSTRACT:
Alkylene glycols are produced from alkylene carbonates by hydrolysis in the presence of water at temperatures of from about 80.degree. to about 200.degree. C. Catalysts, such as alumina, are employed at temperatures from 80.degree. to about 150.degree. C. and only slightly greater than the stoichiometric amount of water is employed to allow the most efficient use of the process.
