Abstract

An easy and efficient procedure of preparation of symmetric organic carbonates in the ionic liquid tributylmethylammonium methanesulfonate ([tbma][MsO]) by dialkylation of potassium carbonate in mild conditions is proposed. Yields by weight of the isolated pure products are 95-97% in 24 h, working in excess of the eco-friendly potassium carbonate.

Keywords: Symmetric carbonates, ionic liquids, esterification, nucleophilic substitution, potassium carbonate
