Ionic compounds having a freezing point of no more than 50 ~C, formed by the reaction of at least one amine salt of the formula R1~R2~R3~R4~N+~X-~ (I) with at least one hydrated salts, 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 R1~, R2~ and R3~ are each independently a C~1 to C~5 alkyl or a C~6 to C~10 cycloalkyl group, or wherein R2~ and R3~ taken together represent a C~4 to C~10 alkylene group, thereby forming with the N atom of formula (I) a 5 to 11 membered heterocyclic ring, and wherein R4~ is hydrogen, or phenyl, or C~1 to C~12 alkyl or cycloalkyl group, optionally substituted with at least one group selected from OH, Cl, Br, F, I, phenyl, NH~2, CN, NO~2, COOR5~, CHO, COR5~ and OR5~, wherein R5~ is a C~1 to C~10 alkyl or cycloalkyl group, and X-~ is an anion capable of being complexed by the said hydrated salt. The compounds are useful as solvents, electrolytes, and catalyts, and have particular application in solvents/electrolytes for metal plating and electropolishing processes, in particular in chromium plating. |
