Claim:
An ionic compound, having a freezing point of up to 100° C. formed by the reaction of at least one amine salt of the formula R 1 R 2 R 3 R 4 N + X − (I) with at least one organic compound (II) which is capable of forming a hydrogen bond with X − , wherein R 1 , R 2 , R 3 and R 4 are each independently:- H, optionally substituted C 1 to C 5 alkyl, optionally substituted C 6 to C 10 cycloalkyl, optionally substituted C 6 to C 12 aryl optionally substituted C 7 to C 12 alkaryl, or wherein R 1 and R 2 taken together represent a C 4 to C 10 optionally substituted alkylene group, thereby forming with the N atom of formula (I) a 5 to 11-membered heterocyclic ring, X − , is NO 3 − , F − , Cl − , Br − , I − , BF 4 − , ClO 4 − , CN − , SO 3 CF 3 − , or COOCF 3 − , and wherein the term “optionally substituted” means that the group in question may or may not be substituted with one or more groups selected from OH, SH, SR 5 , Cl, Br, F, I, NH 2 , CN, NO 2 , COOR 5 , CHO, COR 5 and OR 5 , wherein R 5 is a C 1 to C 10 alkyl or cycloalkyl group, wherein all of R 1 , R 2 , R 3 and R 4 are not identical, and wherein compound (II) is a compound of the formula R 6 COOH, R 7 R 8 NH, R 9 CZNH 2 , or R 10 OH, wherein:-R 6 , R 7 , R 8 , R 10 are each H, a C 1 –C 8 alkyl group, an aryl group, or a C 7 –C 12 alkaryl group optionally substituted with from 0 to 6 group selected from OH, SR 5 , Cl, Br, F, I, NH 2 , CN, NO 2 , COOR 5 , COR 5 and OR 5 , wherein R 5 is H, a C 1 –C 10 alkyl or cycloalkyl group, R 9 is a C 1 –C 8 alkyl group, C 1 –C 12 an aryl group, or a C 7 –C 12 alkaryl group optionally substituted with from 0 to 6 groups selected from OH, SR 5 , Cl, Br, F, I, NH 2 , CN, NO 2 , COOR 5 , COR 5 and OR 5 , wherein R 5 is H, a C 1 to C 10 alkyl or cycloalkyl group, or wherein R 9 is NHR 11 , wherein R 11 is H or a C 1 –C 6 alkyl group, and Z is O and wherein formula (I) and compound (II) are utilized in a molar ration from 1:1.5 to 1:2.5
