Excess Acoustical Study of Binary Liquid Mixture with Experimental Parameters at Different Temperatures
Abstract: Excess acoustical parameters such as excess ultrasonic velocity (UE), excess acoustic impedance (ZE), excess Molar Volume (VmE), excess free length (LfE) and excess adiabatic compressibility (bE) have been discussed between the component molecules in terms of their intermolecular interactions of the binary liquid mixture containing Aniline with Toluene from temperatures T = 303.15 to 318.15 K. These excess parameters have been calculated from the values of densities (r), ultrasonic velocities …

Thermoacoustic Properties of 1-Propanol-n-Hexane and 1-Propanol-Cyclohexane Binary Mixtures: A Comparative Study at 298.15 K
Abstract: This study reports the measurement of ultrasonic velocity (U), viscosity (η), and density (ρ) for the binary liquid mixtures 1-propanol–n-hexane and 1-propanol–cyclohexane at 298.15 K over the full composition range (mole fraction 0.1–0.9). From the experimentally measured data, several important thermodynamic and acoustic parameters, including isentropic compressibility (βₐ), acoustic impedance, intermolecular free length, free volume (Vf), and internal pressure (πᵢ), were systematically derived to assess the magnitude and nature of …

Study of Molecular Interaction in Organic Ternary Liquid Mixtures Containing Toluene
Abstract: Abstract : Interactions of N, N-dimethylformamide with Cyclohexane and Toluene play an important role in their conformational characteristics. The study of these interactions provides an important insight into the ternary mixture. Through this research work, I make an attempt to study the molecular interactions among the constituent molecules at temperatures 288, 298, 308 and 318 K. From these experimental values, various parameters like adiabatic compressibility, free length, acoustic impedance, surface …
