Studies on an ionic liquid prepared from InCl3 and 1-methyl-3-butylimidazolium chloride

The phase diagram of the system InCl3/1-methyl-3-butylimidazolium chloride (MBIC) was constructed by DSC method. A clear colorless and transparent ionic liquid was experimentally observed in InCl3/MBIC system with about mole fraction of InCl3 x=0.50 at ambient temperature. Both Raman scattering and ab initio calculations indicate that InCl4− is the predominant indium-containing species in this liquid.
