A total of sixty-three choline derivative-based ionic liquids in the forms of chlorides, acesulfamates, and bis(trifluoromethylsulfonyl)imides have been prepared and their physical properties (density, viscosity, solubility, and thermal stability) have been determined. Thirteen of these salts are known chlorides: precursors to the 26 water-soluble acesulfamates, 12 acesulfamates only partially miscible with water, and 12 water-insoluble imides. The crystal structures for two of the chloride salts-(2-hydroxyethyl)dimethylundecyloxymethylammonium chloride and cyclododecyloxymethyl(2-hydroxyethyl)dimethylammonium chloride-were determined. The antimicrobial (cocci, rods, and fungi) activities of the new hydrophilic acesulfamate-based ILs were measured and 12 were found to be active. The alkoxymethyl(2-hydroxyethyl)dimethylammonium acesulfamates have been shown to be insect feeding deterrents and thus open up a new generation of synthetic deterrents based on ionic liquids. The alkoxymethyl(2-decanoyloxyethyl)dimethylammonium bis(trifluoromethylsulfonyl)imides have also been shown to act as fixatives for soft tissues and can furthermore be used as substitutes for formalin and also preservatives for blood.

“…[4] ILs have even been used as tools in embalming and tissue preservation in histopathological diagnosis. [5,6] Quaternary ammonium salts (quats), or inverted soaps, are well known cationic surfactants. They each contain at least one or two long (eight or more carbon atoms) alkyl chains and retain their cationic character at any pH.…”

A new one-step procedure is described for the synthesis of disubstituted imidazolium chlorides. 1,3-Dialkoxymethylimidazolium chlorides thus obtained can be employed as synthetic precursors of symmetrical ILs. The salts have been found to exhibit antimicrobial activity and an antielectrostatic effect. Their densities and viscosities have been determined and are reported herein. It has also been demonstrated that the ILs can be decomposed using an aqueous solution of KMnO(4). For each IL, the permanganate index (I(Mn)) has been estimated, which varies with the structure of cation. The only limitation of I(Mn) is the degree to which the IL dissolves in water.

The structures of these compounds were confirmed by X-ray analysis of 2.…”

Saturated or partially saturated heterocyclic compounds were uncovered as interesting and potential ionic liquid media. Zwitterionic compounds with perhydropyrimidinylium, 1,3-diazepinylium and quinazolinylium carbocations were utilized in the preparation of a variety of salts in order to search for new low-melting ionic media. Some of the zwitterionic quinazoline derivatives were also found to be low-melting glasses.
