Abstract

Ionic compounds having a freezing point of no more than 50.degree. C., formed by the reaction of at least one amine salt of the formula R.sup.1R.sup.2R.sup.3R.sup.4N.sup.+X.sup.- (I) with at least one hydrated salt, which is a chloride, nitrate, sulphate or acetate of Li, Mg, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb, Bi, La or Ce; wherein R.sup.1, R.sup.2 and R.sup.3 are each independently a C.sub.1 to C.sub.5 alkyl or a C.sub.6 to C.sub.10 cycloalkyl group, or wherein R.sup.2 and R.sup.3 taken together represent a C.sub.4 to C.sub.10 alkylene group, thereby forming with the N atom of formula (I) a 5 to 11 membered heterocyclic ring, and wherein R.sup.4 is hydrogen, or phenyl, or C.sub.1 to C.sub.12 alkyl or cycloalkyl group, optionally substituted with at least one group selected from OH, Cl, Br, F, I, phenyl, NH.sub.2, CN, NO.sub.2, COOR.sub.5, CHO, COR.sup.5 and OR.sup.5, wherein R.sup.5 is a C.sub.1 to C.sub.10 alkyl or cycloalkyl group, and X.sup.- is an anion capable of being complexed by the said hydrated salt. The compounds are useful as solvents, electrolytes, and catalysts, and have particular application in solvents/electrolytes for metal plating and electropolishing processes, in particular in chromium plating.
