摘要: Abstract Density (ρ), viscosity (η) and speed of sound (μ) values are measured for the binary mixtures 2-chloroaniline with isomeric butanols (1-butanol, 2-butanol, 2-methyl-1-propanol 2-methyl-2-propanol) over entire range mole fraction at temperatures T = (303.15 to 318.15) K. Using experimental data, excess molar volume (VmE), isentropic compressibility (ksE), deviation in (Δη) Gibbs free energy activation viscous flow (ΔG⁎ E) have been calculated. All investigated systems exhibit negative VmE ksE; positive Δη ΔG⁎ E composition range. The calculated properties discussed terms molecular interactions between present mixtures. These functions also correlated using Redlich–Kister type polynomial equation. formation hydrogen bond equimolar mixture is identified by FT-IR values.
