“…At 0.0 mole fraction of aniline, this adhesion value is large in value because of the nonavailability of polar component in the blend. [22,23] This resulting in negative and increment data of πi E shows the aniline contribution develops in the blend, the adhesion becomes cohesive in nature. As the dipolar aniline possesses a strong cohesion, and its interaction with toluene is feeble as reported previously, πi E shifts to positive.…”

Acoustic velocity (U), viscosity (η), and density (ρ) characteristics were conducted for different ternary blends of aniline + toluene mixed with some 1‐alcohols at 303 K. Acoustical quantities such as adiabatic compressibility (β), free length (Lf), free volume (Vf), and internal pressure (πi) are acquired from the obtained results for all the blends, with a perspective to study the nature of molecular interaction. These parameters were analyzed along with their excess values (AE) and are found to be useful in evaluating the strength and magnitude of interaction in the blends. The measurement reveals that the interaction between the aniline‐alcohol complexes predominant the other interaction. The excess parameters are fitted to polynomial‐kind Cibulka formula and the coefficient of the fitting are found to be corroborate this work.

Purpose: To understand the nature of liquids the need of physico-chemical behavior of liquid mixtures or in pure form Sound velocity, viscosity and density values have been calibrated in binary and ternary system of some of the Aniline+1-alkanols with benzene, toluene, and hexane at 303K. Several theoretical models have been applied to evaluate the sound velocity values for the binary and ternary systems compared with the experimental values. Method: The ultrasonic velocity, density and viscosity measured with ultrasonic interferometer, specific gravity bottle with Oswald’s viscometer respectively. The measured ultrasonic velocity compared with theoretical models to understand the existence of molecular interactions from models like Nomoto’ Relation, Free Length Theory, ideals mixture relation etc. Results: NR predictions provide better closeness with test values and FLT predictions are not completely acceptable. FLT prediction is found to fail even for pure liquids. IMR predictions are more acceptable than NR, only for aniline + 1-pentanol binary and NR seem to be the best of all other systems. In binary, IMR predicted values are always lower than test values, but NR predictions are, in most cases, higher than test values. In ternary systems, especially at high mole fractions of aniline, the predicted sound velocity values (NR & IMR) are always lower than the experimentally observed values. Among the many theories considered, NR gives the best prediction of sound speed. The sequence of qualifications for predicting sound speed decreases as NR and IMR and FLT are completely invalid for all considered systems. Conclusion: Strong molecular interaction with the structure formation increases with mole fractions. Azeotropic destruction has been found to be the most common of the compounds considered.
