Densities, a, and viscosities, O, of pure 1-hexyl-3-methylimidazoliumtetrafluoro borate ([C6mim][BF4]) and 1-propanol, and their binary mixture { x1[C6mim][BF4] + x21-propanol} were measured at atmospheric pressure and in the temperature range of (293.15 to 333.15) K. The excess molar volumes, , thermal expansion coefficients, pounds\, and their excess values, , isothermal coefficient of excess molar enthalpy , and viscosity deviations, poundsGpoundsb, were calculated from the experimental values of densities, and viscosities. The excess molar volumes of the binary mixture are negative over the entire mole fraction range and increase with increasing temperature. Viscosity deviations are negative over the entire mole fraction range of the mixture and decrease with increasing temperature. The obtained excess molar volumes and viscosity deviations were correlated with the Redlich-Kister equation. The experimental results have also been used to examine the applicability of Prigogine-Flory-Patterson (PFP) theory in prediction excess molar volume of the binary mixture. It is indicated that agreement between excess molar volumes calculated via PFP theory with the experimental results are good in all temperatures.
