실험 절차

First, the ionic fluid was prepared from the two starting materials: 1-ethyl-3-methylimidazolium chloride and aluminum trichloride. Both of these materials are in solid form at room temperature prior to mixing (the former is a crystalline substance; the latter, a powder). The two solid reactants were combined in about equimolar amounts (4.4 g imidazolium, F. W.=146.2; 4.0 g AlCl3, F. W.=133.34 in a pyrex reaction vessel. The reaction began almost immediately with only modest shaking of the reaction vessel; within moments product ionic liquid, 1-ethyl-3-methylimidazolium tetrachloride, was formed, as evidenced by the transformation of all of the solids into a liquid. The liquid was a greenish color, due to contaminants present in the two starting materials. Without contaminants present, the ionic liquid product should be colorless. Upon combining the two starting materials, the reaction vessel promptly became hot to the touch, until it could no longer be handled through ordinary laboratory disposable plastic gloves. Substantial heat was generated throughout the reaction.
