摘要：

The vapor-liquid equilibria of three alcohol-alcohol binary mixtures (methanol-ethanol, methanol-1-propanol and ethanol-1-propanol) and three alcohol-water binary mixtures (methanol-water, ethanol-water and allyl alcohol-water) containing calcium chloride were measured at 298.15 K using a flow-type apparatus. The measured data of each ternary system were correlated by the use of a semi-empirical model proposed by Hala. It was found that the model with the optimal value of the exponent beta = 5.0 in the electrostatic interaction term, originally given as 3/2 by Hala, gives reasonable prediction to all the systems in this study.
