    • The present invention relates to ionic liquids of the formula: (Mm+)xH+ ynN+R1R2R3R4 Z-N(-CHXCOO-)pY2-p or (Mm+)x H+ y nP+R1R2R3R4Z-N(-CHXCOO-)pY2-p wherein any one of R1 to R4 independently represents a hydrogen, alkyl, cycloalkyl, aryl or aralkyl group that may be unsubstituted or substituted with one or more groups selected from OH, Cl, Br, F, I, phenyl, NH2, CN, NO2, an ether group, COOR5, CHO, COR5 or OR5, wherein R5 is an alkyl or cycloalkyl group, and wherein two of the groups R1 to R4 together with the N atom may form a heteroaromatic or heterocyclic group such as a pyridinium, pyrrolidinium or imidazolium group; the Z-N(-CHXCOO-)pY2-p is the anion derived from a chelating agent, wherein Z is a group selected from hydrogen, alkyl, an alkyl group optionally substituted with one or more carboxylate groups, hydroxyl groups and/or optionally containing one or more ether functionalities, or Z is a group of the formula -CH2-CHR6-R7-N-(CH2COO-)2, R6 is hydrogen or a C1-C3 alkyl group, R7 is a single bond, a C1-C3 alkylene group or one or more groups of the formula -N(CH2COO-)-CH2-CHR6-R8-, R8 is a single bond or a C1-C3 alkylene group, p is 2 or 1, X is H, an aryl group that may be unsubstituted or substituted with an OH and/or CH3 substituent, or CH2COO-, and when p is 1, Y is H, a benzyl group that may be unsubstituted or substituted with an OH and/or CH3 group, or a phenyl group that may be unsubstituted or substituted with an OH and/or CH3 substituent, Mm+ is a m-valent metal cation, n is 1 or higher, x is from 0 to 5, y is from 0 to 3, the total positive charge of (Mm+)x, H+ y,and nN+R1R2R3R4 or nP+R1R2R3R4 equals the negative charge of the Z-N(-CHXCOO-)pY2-p anion, wherein at least one of the following conditions is fulfilled: i) the chelating agent has a connectivity index 1 X/3 X of below 2.17, ii) at least two different cations are present in the salt, whereby a proton cation does not count as one of the at least two, iii) at least one cation is a bivalent, trivalent, tetravalent or pentavalent cation, and having a melting point below 120°C. The invention further relates to a process to prepare them and their use.
