Dynamic Viscosities of (Methyl Acetate or Methanol) with (Ethanol, 1-Propanol, 2-Propanol, 1-Butanol, and 2-Butanol) at 298.15 K

摘要: Viscosities have been measured for the binary mixtures methyl acetate + (methanol, or ethanol, 1-propanol, 2-propanol, 1-butanol and 2-butanol), methanol (ethanol, 2-butanol) their viscosity deviations were evaluated at 298.15 K atmospheric pressure over entire composition range. Several semiempirical relations proposed to estimate dynamic viscosity, results compared with experimental data. The UNIFAC-VISCO group contribution method, Lobe's volume fraction exponential model, thermodynamics model (GC-UNIMOD) used predict viscosity.
