| ABSTRACT: The density (ρ), speed of sound (u), and viscosity (η) of the binary mixtures of (diethylene glycol monoethyl ether (carbitol) and water, ethanol, N,N-dimethylformamide) have been measured in full concentration range at T = 288.15, 298.15, 308.15, and 318.15 K and p = 0.0868 MPa. Using the experimental data, the molar volume (Vm), excess molar volume (Vm E ), isentropic compressibility (κs), excess molar isentropic compressibility ( s,m κ E ), and viscosity deviation (Δη) were calculated. The most negative values of Vm E and s,m κ E and positive values of Δη obtained for the carbitol + water mixture are indicative of the strong interactions between different components relative to two other systems. The values of ρ, Vm, and κs for the studied mixtures were correlated using the Jouyban−Acree model with high accuracy. Furthermore, the obtained values of Vm E , s,m κ E , and Δη were described by the Redlich−Kister equation and reasonable standard deviations were obtained. |
