Triethyl amineas well as methanol and ethanol are important aliphatic organic amino compound, which draw their importance as excellent solvents. The densities (ρ) and ultrasonic velocities (u) of binary mixtures of triethyl amine with methanol and ethanol have been determined experimentally at 298.15K, 303.15K and 308.15K respectively. Isentropic compressibility, intermolecular free length, molar volume, available volume and free volume have been computed utilizing these experimental data. The nonlinear variation of these parameters shows the presence of interaction and their excess values is indicative of interaction between the components molecules in both systems.Keywords

Ultrasonic velocity, density and viscosity have been determined experimentally and free volume as well as internal pressure were computed for the binary mixtures of n. butanol with aniline, N-methylaniline and N, N-dimethylaniline. Excess values of viscosity, free volume and internal pressure were also deduced for these systems. The results have been discussed in the light of existing theories of molecular interaction involved and chemical constitution of the liquid components.Keywords
