Ultrasonic Studies in Binary Liquid Mixtures of Butylamine and Iso-Butylamine with 1-Decanol at 293, 303 and 313 K
Abstract: Normal 0 false false false EN-US X-NONE X-NONE Acoustic parameters like isentropic compressibility, acoustic impedance and intermolecular free length along with internal pressure of butylamine and iso-butylamine with 1-decanol have been determined from sound speed, density and viscosity measurements at 293, 303 and 313 K over the entire range of composition. These derived parameters were used to calculate excess functions like deviation in isentropic compressibility, excess acoustic impedance, excess intermolecular …

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 …

Volumetric and Viscometric Studies of Molecular Interactions in Binary Mixtures of Butylamine and Iso-butylamine with 1-decanol at Different Temperatures
Abstract: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 The increasing use of alkylamine and alkanol in various chemical and industrial processes encouraged investigation on the thermodynamic and transporting properties of alkylamine, alkanol and their mixtures for obtaining extensive information. Excess molar volume (VE), deviation in viscosity (Dh) and excess Gibbs free energy of activation of viscous flow (G*E) have been calculated from measured densities and viscosities of pure butylamine …

Ultrasonic Study of Molecular Interactions in Organic Liquids at Various Temperatures and Concentrations
Abstract: The ultrasonic velocity was measured for water and glacial acetic acid in their pure state and in their binary mixtures. The ultrasonic velocity was measured also for the solution of salicylic acid in glacial acetic acid. Relative density and relative viscosity were also measured at various temperatures and concentrations. The parameters like adiabatic compressibility, acoustic impedance, relaxation time and attenuation were determined. This study is helpful for the understanding of …

Phase Transition and Molecular Orientational Studies on Nematic Dimmer and Cholesteric Materials
Abstract: The binary mixture of nematic dimmer and cholesteric compounds viz., cholesteryl nonanoate (CN) and 1,7-bis-4-(4′-cyanobiphenyl) heptane (CB7CB) exhibits very interesting liquid crystalline phase’s at large range of concentrations and temperature. The concentrations with lower/higher percentage of CB7CB exhibit cholesteric and reentrant smectic-A phases sequentially when the specimen is cooled from its isotropic phase. The molecular tilt and birefringence have been discussed in the region of smetic-A and smectic-C phases, respectively …
