Densities and Viscosities of Binary Mixtures of Cyclohexanone and 2-Alkanols

Densities and viscosities of mixtures of cyclohexanone with 2-alkanols, namely, 2-propanol, 2-butanol, 2-pentanol, 2-hexanol, and 2-heptanol, have been measured as a function of composition range at <i>T</i> = (298.15, 303.15, 308.15, and 313.15) K and ambient pressure. Excess molar volumes <i>V</i>_m^E and viscosity deviations Δη were calculated and correlated by the Redlich–Kister type function to derive the coefficients and estimate the standard error. For mixtures of cyclohexanone with used 2-alkanols, <i>V</i>_m^E is positive, and Δη is negative over the entire range of mole fraction. The effect of temperature and chain length of the 2-alkanols on the excess molar volumes and viscosity deviations of its mixtures with cyclohexanone is discussed
