Abstract

Internal pressures of the ternary and sub-binary mixtures of Benzene (1) +Hexane (2) + n-Butanol (3) have been computed from ultrasonic velocity measurements at different mole fractions in the temperature range of 300C-450C. The present work has been carried out to study the variation of internal pressure with temperature and composition of polar binary mixtures. The equation proposed by Andiappan et.al, for evaluating internal pressures of binary liquid mixtures has been modified and extended in the present work for the Ternary systems. The internal pressures computed with the help of the modified relation shows close agreement with observed values. The absolute deviation between the calculated and observed values from 1.15% to 1.9% for the ternary system studied.

 

Keywords: Ultrasonic velocity, density, molecular weight and internal pressure.
