Thermodynamical Studies on Binary Systems Consisting of Polar and Non-polar Liquids. V. The Anomalies in the Binary Systems of Polar Liquid with Aromatic Non-polar Liquid

Abstract The anomalous stabilization energy for the systems containing polar and aromatic nonpolar liquids was evaluated on reasonable assumptions. The van Laar coefficient due to this stabilizing effect was found to be dependent on the concentration. The stabilization effect corresponding to the concentration dependent part of the van Laar coefficient was explained by the cooperative orientation of aromatic nonpolar molecules around the polar molecules.
