Thermodynamic properties of binary mixtures containing N,N-dimethylformamide + 2-alkanol: Cubic and statistical associating fluid theory-based equation of state analysis

• Densities and viscosities at various temperatures have been measured.
• SAFT and PC-SAFT were applied to predict the volumetric behavior of mixtures.
• The best predictions were achieved with the PC-SAFT equation of state.
• PRSV equation of state (EOS) has been used to predict the binary viscosities.

Densities and viscosities of mixtures of N,N-dimethylformamide with 2-propanol, 2-butanol, 2-pentanol, 2-hexanol, and 2-heptanol have been measured as a function of composition range at T = (298.15, 303.15, 308.15, 313.15) K and atmospheric pressure. Excess molar volumes VmE and viscosity deviations Δη were calculated and correlated by the Redlich–Kister type function. The statistical associating fluid theory (SAFT), and perturbed chain statistical associating fluid theory (PC-SAFT) were applied to correlate and predict the volumetric behavior of the mixtures. The best predictions were achieved with the PC-SAFT equation of state. Also the Peng–Robinson–Stryjek–Vera (PRSV) equation of state (EOS) has been used to predict the binary viscosities.
