ABSTRACT

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, 303.15, 308.15, 313.15) K and ambient pressure. Excess molar volumes and viscosity deviations Ac 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, is positive and Ac 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.
