IONIC LIQUID MISCIBLE WITH VARIOUS POLAR/NONPOLAR SOLVENT AND METHOD FOR PRODUCING THE SAME

Japanese Patent JP2009249379

A

To provide an ionic liquid miscible with various polar/nonpolar solvents and a method for producing the liquid.

Provided is an ionic liquid containing one or more compounds expressed by chemical formula: (Cat+)(R'COO-), wherein Cat+ is a cation selected from quaternary ammonium, quaternary phosphonium, sulfonium, imidazolium, pyridinium, pyrazolium, piperidinium, pyrrolium, pyrrolidinium, triazolium and a mixture of two or more of the above; and R' is a hydrocarbon group having 4-30 carbon atoms and containing one or more unsaturated bonds. The ionic liquid is partially or completely miscible with various polar and/or nonpolar solvents, and is usable at normal temperature or low temperature as a solvent, solvent additive, electrolyte, thermal medium, electrically charged material, thermal medium additive, charged material additive and phase transfer catalyst, and the manufacturing method can reduce production cost.
