Abstract:
1. An ionic liquid composition, comprising greater than 70 weight percent of an ionic liquid comprising: (a) a cation independently selected from the group consisting of: substituted or unsubstituted pyridinium, pyridazinium, pyrimidinium, pyrazinium, imidazolium, pyrazolium, thiazolium, oxazolium, triazolium, imidazolinium, methylpyrrolidinium, isothiazolium, isoxazolium, oxazolium, pyrrolium, and thiophenium, wherein when substituted, the substituent group may be one or more of halo, alkyl, and aryl groups, and two adjacent substituents may be joined together to form an alkylene radical consisting of from about six to about eighteen carbon atoms to form a ring structure converging on N; and quaternary ammonium cation substituted by groups selected from the group consisting of alkyl and aryl groups; and tetrabutyl ammonium, tributylmethyl ammonium, tetrabutyl phosphonium, tetraethyl ammonium, N,N-dialkyl pyrrolidinium, trimethyl 2-hydroxyethyl ammonium, N,N′-dialkyl imidazolium, N-alkylpyridinium, 1-methyl-3-hexyl imadazolium and a mixture thereof; and (b) an anion having the following structure: wherein R R R R wherein the ionic liquid has a melting point that is less than about 100° C.
