Studying Intermolecular Interactions in Binary Systems of Butyl Acetate-Dibutyl Phthalate and Butyl Acetate-Dioctyl Phthalate

Studies of intermolecular interactions in butyl acetate-dibutyl phthalate and butyl acetate-dioctyl phthalate systems show that except for excess volume, deviations of properties from an ideal mixture are reduced as the temperature rises. Results indicate considerable van der Waals forces and confirm the effect the size of molecules has on the properties of binary mixtures. Experimental data on density, refractive index, viscosity, excess molar volume, and other properties are presented for systems and pure substances.
