A falling-body viscometer was designed and manufactured to determine the densities and viscosities of liquids at high temperatures and pressures. The densities and viscosities for pure [bmim][PF6], [bmim][PF6] + ethanol, and [bmim][PF6] + benzene binary systems were determined in the temperature range of (313.2 to 413.2) K and in the pressure range of (0.1 to 25.0) MPa. The viscosities of [bmim][PF6] + ethanol, and [bmim][PF6] + benzene binary systems were correlated with temperature, pressure, and composition by correlation equations. The correlation coefficients (R) are 0.999 and 0.999 for [bmim][PF6] + ethanol and [bmim][PF6] + benzene systems, respectively.
