Abstract
Densities (ρ), viscosities (η) and refractive indices (nD) were measured for the binary mixtures of o- and m-chloroaniline with 2-alkoxyethanols like 2-methoxyethanol, 2-ethoxyethanol and 2-butoxyethanol at 303.15K. From the experimental data, the values of excess molar volume (VE), deviation of viscosity (ηE), deviation of refractive index (ΔnD), excess molar refraction (RmE) and excess Gibbs free energy (ΔG⁎E) for the six binary mixtures were calculated and the values are fitted with Redlich–Kister polynomial equation. The values of all calculated parameters of the binary mixtures and their deviations indicate a strong specific type of interaction between the amino group (NH2) of chloroanilines with hydroxyl group (OH) of 2-alkoxyethanols.
