Eutectic mixtures of urea and a range of quaternary ammonium salts are liquid at ambient temperatures and have interesting solvent properties.

Preparation of novel, moisture-stable, Lewis-acidic ionic liquids containing quaternary ammonium salts with functional side chains

A range of novel, moisture-stable, Lewis-acidic ionic liquids has been prepared by mixing appropriate molar ratios of MCl2 (M = Zn and/or Sn) and quaternary ammonium salts of formula [Me3NC2H4Y]Cl (Y = OH, Cl, OC(O)Me, OC(O)Ph); the influence of substituent Y and metal M on the physical properties of the melts has been investigated.

Electrodeposition of chromium black from ionic liquids

SUMMARY The efficient electrodeposition of chromium from an ionic liquid formed between choline chloride and CrClr6H20 is demonstrated. The addition of lithium chloride is found to allow the deposition of black chromium films that afford excellent corrosion resistance. The deposits formed are crack-free and made up of nanocrystalline material.

Novel ambient temperature ionic liquids for zinc and zinc alloy electrodeposition

SUMMARY This work shows that novel ambient temperature ionic liquids can be produced from substituted quaternary ammonium salts and some metal salts. The ionic liquids are sufficiently conducting to allow electrochemical investigations to be carried out. Data on the electrochemical reduction of the metal ions is presented together with information on the deposit morphology of Zn, and Zn/Sn and Zn/Co alloys. The low cost and low toxicity of the ionic liquids makes possible their use for large-scale metal finishing applications.
