Experimental vapor-liquid equillibrium data at low pressure are presented for ethanol/water mixtures containing sodium chloride and calcium chloride at constant molalities. In addition, the results for an ethanol/water mixture saturated with sodium chloride are given. The saturation concentrations of ethanol/water mixtures at boiling temperature and 123.1 mbar are reported. The data are compared with the predicted results using an extended UNIQUAC model for electrolyte systems published by Macedo et al.
