A wries of [Emim] Br - FeCl3 were rapidly synthesized by altering the molar fraction of FeCl3 in ionic liquids. And the acidity of acidic ionic liquids were studied by IR technique using acetonitrile as a probe molecule. The experiment results indicated that ionic liquids exhibited Lewis acidity and the anion of ionic liquids had great effects. The acid strength of ionic liquids rised with the increase of the amount of FeCl3.
