Densities and viscosities of binary mixtures of ethylmethylketone and 2-alkanols; application of the ERAS model and cubic EOS

Densities and viscosities of binary mixtures of ethylmethylketone with 2-propanol, 2-butanol, 2-pentanol, 2-hexanol, and 2-heptanol, have been measured as a function of composition range at temperatures of 298.15 K, 303.15 K, 308.15 K, 313.15 K and ambient pressure. Excess molar volumes VmE and viscosity deviations Δη   were calculated and correlated by the Redlich–Kister equation to derive the adjustable parameters and estimate the standard error. For mixtures of ethylmethylketone with used 2-alkanols, VmE is positive and Δη is negative over the entire range of mole fraction. The ERAS-model has been applied for describing the binary excess molar volumes and also Peng–Robinson–Stryjek–Vera (PRSV) equation of state (EOS) has been used to predict the binary excess molar volumes and viscosities.

► Densities and viscosities and at various temperatures have been measured.
► Few data for these systems are available.
► ERAS model and cubic EOS were used to correlate and predict the experimental data.
► Cubic EOS show lower deviations comparing by the ERAS model.
