Thermodynamical Studies on Binary Systems Consisting of Polar and Non-polar Liquids. VI. Refined Calculation of the Electrostatic Part of van Laar Coefficients and Comparison with the Experimental Results

The electrostatic parts of van Laar coefficients for binary systems of polar and non-polar liquids were calculated, assuming that (1) the polar molecule is anisotropic in polarizability, (2) that the polar molecule is an ellipsoid, and (3) that the dipole is a point dipole and its position is not at the center of the molecule. The results were compared with the experimental results. The agreement between the experimental values and the...
