The effect of lithium chloride (LiCl) salt on vapor-liquid equilibrium (VLE) of the binary ethanol-water system has been experimentally investigated at atmospheric pressure using modified Othmer equilibrium still. An effect of salt content in the range of 0 to 10 wt % has been investigated. The addition of lithium chloride to the solvent mixture produced an important salting-out effect over the alcohol and the azeotrope tends to be shifted when the salt content increased. The experimental data were correlated by the following models Margules, Van Laar, Wilson, NRTL, UNIFAC equation.
