“…One of the advantages of the application of Eq. (15) to hypothetical solutions is that, as has already been shown for the 1-butanol(1)-water(2) binary [2], the mutual solubility data provide the same TC line with that determined from the constant-temperature and constant-pressure VLE data. In Fig.…”

“…It has already been shown that the TC line for the 1-butanol(1)-water(2) binary determined from the VLE data is identical with that determined from the binary LLE data. It was also suggested that the data convergence of the TC line from the LLE data are much better than that from the VLE data [2].The purpose of the present investigation is to show that all of the mutual solubility data from the literature conform to their TC lines, and that their data convergences are excellent. …”

“…Meanwhile, D = 0 is also satisfied at Δx 1 = 0, even if A ≠ B, as is the case in highly polar mixtures. Based on these facts, the following polarity exclusion factor, β, was defined [2], and an empirical relationship was proposed as follows:…”

“…However, a method for determining the thermodynamic consistency of the mutual solubility data has not yet been established. Meanwhile, Kato [2] recently showed that TC lines are useful for the thermodynamic consistency (TC) identification of the binary vapor-liquid equilibrium (VLE) data [3]; i.e., it was shown that each binary has a straight TC line represented as β = aP b , where β and P denote the polarity exclusion factor and the system pressure, respectively, while a and b are constants.

It has already been shown that the binary vapor-liquid equilibrium (VLE) data form thermodynamic consistency (TC) lines, defined using the polarity exclusion factor; i.e., the ratio of data deviation from the Gibbs-Duhem equation, F, to |B-A|, where A and B denote Margules parameters representing the VLE data. The present investigation shows that the mutual solubility data from the literature converge to TC lines. It was shown that fluctuations of the TC lines from the LLE data are less than those from the VLE data. IntroductionMutual solubility data are of practical importance for the rational design of solvent selection and the prediction of ternary liquid-liquid equilibria (LLE). A significant number of mutual solubility data can be found in the literature [1]. However, a method for determining the thermodynamic consistency of the mutual solubility data has not yet been established. Meanwhile, Kato [2] recently showed that TC lines are useful for the thermodynamic consistency (TC) identification of the binary vapor-liquid equilibrium (VLE) data [3]; i.e., it was shown that each binary has a straight TC line represented as β = aP b , where β and P denote the polarity exclusion factor and the system pressure, respectively, while a and b are constants. It has already been shown that the TC line for the 1-butanol(1)-water(2) binary determined from the VLE data is identical with that determined from the binary LLE data. It was also suggested that the data convergence of the TC line from the LLE data are much better than that from the VLE data [2].The purpose of the present investigation is to show that all of the mutual solubility data from the literature conform to their TC lines, and that their data convergences are excellent.
