Salt effect on vapor–liquid equilibria for binary systems of propanol/CaCl2 and butanol/CaCl2

The binary vapor–liquid equilibrium (VLE) data for salt-containing systems of 1-propanol/CaCl2, 2-propanol/CaCl2, 1-butanol/CaCl2 and 2-butanol/CaCl2 were determined and correlated. The UNIQUAC model was used to correlate the VLE data, and optimal parameters of the model were obtained. The results show that the UNIQUAC model is suitable to correlate the VLE data.
