New Ionic Liquids with Organic Anions

Abstract

A series of 1-alkylimidazole and 1-alkoxymethylimidazole has been converted to the ionic form. The resulting salicylates and lactates constitute a new category of ionic liquids. They are air and water stable. Some physical properties of these salts were measured, including melting point, boiling point, density and their solubility in some common organic solvents and in water. For 1-alkyl- and 1-alkoxymethylimidazolium lactates values of minimal inhibitory concentration (MIC) and of minimum biocidal concentration (MBC) were determined. Effects of lactate structure on microbiological activity were defined. In aqueous solution the obtained lactates reacted with ozone, unlike their commercially available analogs.
