TL;DR: In this paper, a survey of the available data of the experimental surface tension data for refrigerant binary systems is presented, and a new equation for the prediction of the surface tension of binary systems based on the Corresponding States Principle theory is proposed.
Abstract: This work presents a literature survey of the available data of the experimental surface tension data for refrigerant binary systems. The experimental data were collected for the following binary systems: R32-R227ea, R32-R125, R32-R134a, R290-R32, R125-R152a, R290-R152a, R290-R600a, RE170-R290, R143a-R134a, R125-R134a, R125-R143a, R134a-R152a and R143a + R227ea. Two recently proposed equations for the prediction of the surface tension of pure fluids were evaluated for their abilities to predict the surface tension of binary systems. A new equation for the prediction of the surface tension of refrigerant binary systems based on the Corresponding States Principle theory is proposed.

TL;DR: In this paper, the presence of a specific interaction, of this nature has the effect of reducing the magnitude of all the thermodynamic excess functions from their "normal" large, positive values.
Abstract: RECENTLY there has been much interest in the thermo-dynamic properties of binary mixtures of aromatic fluorocarbons and aromatic hydrocarbons. Experimental studies of the phase diagrams1,2, excess volumes3 and excess enthalpies4 of mixing can be interpreted by assuming that intermolecular complexing exists between the two components. This complexing is believed to result from charge–transfer interaction, with the fluorocarbon acting as the electron acceptor. The presence of a specific interaction, of this nature has the effect of reducing the magnitude of all the thermodynamic excess functions from their “normal” large, positive values. For example, in the system hexafluorobenzene + cyclohexane where there is little possibility of charge–transfer interaction, the excess free energy, enthalpy, entropy and volume are all large and positive, whereas these functions are all negative in the system hexafluorobenzene + mesitylene where the hydrocarbon is a strong electron donor. The system hexafluorobenzene + benzene is found to occupy an intermediate position.

TL;DR: Cocero et al. as mentioned in this paper used the Redlich-Kister equation with coefficients determined by regression through minimization of the sum of deviations in vapor phase compositions to obtain the molar excess Gibbs energies.
