Abstract
Ionic compounds with a freezing point of up to 100° C. are formed by the reaction of an one amine salt of formula (I) RRRRNX, such as choline chloride with an organic compound (II) capable of forming a hydrogen bond with X; such as urea, wherein the molar ration of I to II is from 1:1.5 to 1:2.5. R, R, Rand Rmay be H, optionally substituted Cto Calkyl, optionally substituted Cto Ccycloalkyl, optionally substituted Cto Caryl, optionally substituted Cto Calkaryl, or Rand Rtaken together may represent a Cto Coptionally substituted alkylene group, thereby forming with the N atom of formula I a 5 to 11-membered heterocyclic ring and all of R, R, Rand Rare not identical, Xmay be NO, F, Cl, Br, I, BF, ClO, CN, SOCF, or COOCF. The ionic compounds are useful as solvents, and electrolytes for example in electroplating, electrowinning, and electropolishing, and as catalysts.
