Estimation of acoustic nonlinearity parameter and molecular characteristics of ternary liquid mixtures at different temperatures

Abstract

The acoustic nonlinearity parameter (B/A) of ternary liquid mixtures of heterocyclic compounds viz. pyridine and quinoline with phenol in benzene has been evaluated at 308.15, 318.15, and 328.15 K by three different methods viz. Tong–Dong method, Beyer’s method, and Beyer’s method using Tong–Dong coefficients. The molecular interactions in the liquid mixtures are explained on the basis of excess nonlinearity parameter ((B/A)E). Sehgal’s relations for calculating the molecular properties for pure liquids are extended to the ternary liquid mixtures.
