ABSTRACT

Acoustical investigations for the binary mixtures of phosphinic acid (Cyanex 272), used as liquid liquid extractant, have been made in various diluents such as benzene, toluene, and xylene from ultrasonic velocity and density measurements at temperature 303.15 K and atmospheric pressure. This study involves evaluation of different thermo-acoustic parameters along with the excess properties, which are interpreted in the light of molecular interaction between a polar extractant, Cyanex 272 with non-polar diluent, benzene and weakly polar diluents, toluene and xylene. The excess values are correlated using Redlich Kister polynomial equation, and corresponding adjustable parameters are derived.
