“…We tested these mixing rules on equimolar binary mixtures, and found that at liquid-like densities, the Kay's mixing rules did a very reasonable job. We have found out this to be true for some other properties as weil, as have others [4,5]. We then examined the number of components, such mixtures need to be characterized as, to get accurate values of the transport coefficients.…”

“…For example, both n ‐heptane/ n ‐tridecane and ethanol/1‐pentanol were always used as the reference fluids to calculate the surface tensions of pure alkanes and alcohol compounds, respectively. The CS principle can also be combined with the phenomenological scaling and renormalization group theory for the calculations of pure liquids and their mixtures in a relatively wide range of temperature . Furthermore, the CS model was extended to calculate the surface tensions of polymers, liquid metals, ionic liquids (ILs) .…”

A generalized surface tension model for various types of liquid mixtures by coupling the equation of state for square-well chain fluids with variable ranges and Butler type method was presented. Transferable molecular parameters fitted from experimental pVT of pure fluids were used. The reliability of this model were tested with liquid mixtures including 87 conventional fluid mixtures, 20 aqueous alcohol-amine solutions, 12 ionic liquid solutions, 7 polymer solutions, and 4 liquid alloys. The overall average absolute deviations in correlations with one parameter for all binary mixtures, in predictions for all conventional binary mixtures except aqueous solutions and for all ternary mixtures are 1.94%, 1.82%, and 2.69%, respectively. The potential application of the model in simultaneously describing the phase equilibrium and surface tensions was partially verified. The results demonstrate that this model has an overall robustness and reliability in calculations of surface tensions for various liquid mixtures.

Therefore, the accurate determination and adjustment of surface tensions are essential to the development of the above chemical processes. As such, a robust model for surface tensions plays a central role in the task for saving time, labor, and cost.So far, many efforts have been contributed to develop the surface tension models for pure compounds or mixtures based on empirical and/or theoretical methods.
