Internal Pressures

The Internal pressures of Ternary and their Sub-Binary liquid mixtures of benzene(1) + hexane(2) + sec-butyl alcohol(3) were calculated using density, velocity and molar refraction from the temperature range of 303.15K-318.15K. For the Binary liquid mixtures, the Experimental Internal pressure values were correlated through an equation proposed by Andiappan et.al. For the Ternary liquid mixture, the Experimental Internal pressure values were correlated through an equation proposed by us. The Experimental values and the Theoretical values are in close agreement with each other

General Method

Because of the relevance of internal pressure data to sonochemical kinetics, some interest attaches to expressions which permit evaluation of Pi from readily available or easily measured quantities. One such expression is developed in this paper. It relates Pi to the velocity u of ultrasonic waves transmitted through the liquid and takes the form u√D = K′√(Rm)Pi where K′ is a constant proportional to √(Cp/Cv)√(1/RT), and D and Rm denote the density and molar refraction of the liquid.The utility of this expression is tested against some 100 liquids (including a few binary liquid mixtures and aqueous electrolyte solutions), and it is shown that the equation offers an acceptable and quite general method for calculating Pi.
