Air and water stable 1-ethyl-3-methylimidazolium based ionic liquids

Abstract
A series of novel air and water stable low melting salts based upon the 1-ethyl-3-methylimidazolium cation (EtMeim+) have been prepared and characterized; two salts, [EtMeim]BF4 and [EtMeim]MeCO2, are liquids under ambient conditions.
