The effect of salt on vapor-liquid equilibria for ethyl acetate + ethanol + CaCl2 and + LiCl was measured by using headspace gas chromatography (HSGC) at 313.15 K. Applying a HSGC technique to the measurement of VLE has three advantages, namely, a short measurement time, a small sample volume, and minor skills required. As a result, relative volatility was increased with salt concentrations. LiCl showed stronger effect than CaCl2. The observed data were well correlated with a modified solvation model and with an electrolyte NRTL model. The azeptropic points were estimated by the modified solvation model. It was confirmed that the point was observed to shift to the ethyl acetate-rich region in CaCl2 system and that LiCl broke the azeotrope.
