摘要: Abstract Viscosity η and surface tension σ were measured for binary mixtures of N,N -dimethylformamide DMF with pentan-1-ol, hexan-1-ol, heptan-1-ol at T = (298.15, 303.15, 308.15, 313.15) K atmospheric pressure over the entire mole fraction range. Deviations in viscosity Δ Δσ calculated using experimental results. Moreover, values excess Gibbs free energy activation G ∗E , enthalpy H entropy S these determined. measurements systems correlated Grunberg Nissan, three-body four-body McAllister expressions. deviation, deviation functions fitted to method Redlich–Kister (R–K) polynomial estimate coefficients standard deviations. The effects chain length alkan-1-ols temperature on thermodynamic properties studied.
