Ultrasonic velocity, density, viscosity for the ternary mixture of (benzene + chloroform + cyclohexane) at different temperatures

Ultrasonic velocity (U), density (ρ), viscosity (ƞ) for the ternary mixture of benzene + chloroform + cyclohexane in the whole range of composition has been carried out at various temperatures 303.15, 308.15 and 313.15K. From the measured parameters U, ρ and ƞ, some derived parameters β, Lf, Vf, πi, Z, R,W with molar enthalpy (Hm) and apparent molar volume (ɸv) are also estimated. The decreasing trend of ƞ, R,W, Hm, and ɸv with concentrations and other parameters are in increasing trend were observed. The trend of acoustical and physico-chemical parameters confirm the dynamics of molecules at higher temperature and the magnitude of intermolecular interactions among the constituents of the mixtures always reflects the nature of substance. The role of enthalpy and apparent molar volume has been used to determine their thermal response. The sign and magnitude of these properties are evident for the nature of interactions between component molecules.
