ABSTRACT:
Ethylene glycol carbonate (EGC) can be obtained in purified form from contaminated material which contains impurities from the production or work-up process, by subjecting it to treatment with activated carbon. The treatment is carried out at 40.degree.-250.degree. C. and at 1-200 bar. The activated carbon has a BET surface area of 200-3,000 m.sup.2 /g.
