Volume : I, Issue : IX, October - 2011 THEORETICAL ESTIMATION OF INTERNAL PRESSURE AND EXCESS INTERNAL PRESSURE IN BINARY LIQUID MIXTURES P. PAUL DIVAKAR,K. SAMATHA DOI : 10.9780/22307850, Published By : Laxmi Book Publication Abstract : In recent years, in the study of molecular interactions in binary liquid mixtures by
acoustical methods, internal pressure has gained significant interest. Several
attempts have been made to calculate the internal pressure of liquids and liquid
mixtures theoretically. Here we made use of two empirical methods to estimate the
internal pressure in four binary liquid mixtures viz., cyclohexanone with isopropyl
acetate and isobutyl acetate and N,N-Dimethyl acetamide with o-cresol and mcresol.
The ultrasonic velocity (U), density (ρ) and viscosity (η) have been
measured for the said binary mixtures at 308 K. Excess internal pressure has also
been calculated from the experimental data of pure liquids and liquid mixtures. The
excess values give better understanding of the molecular interactions between the
components.
