  • Measurement and correlation of the excess properties of ternary mixture of ▫${x_1[Hmim][BF_4]+x_21-Propanol +x_3$▫2-Propanol} at different temperatures
    Kermanpour, F ; Sharifi, Tayebeh
    In the present work, the density, ρ, and viscosity, η, of a binary mixture of {x11-propanol + x22-propanol}, along with a ternary mixture of {x11-hexyl-3- methylimidazolium tetrafluoroborate + ... x21-propanol ([Hmim][{BF4]) + x32-propanol} were measured over the entire composition range at (293.15 to 333.15) K and ambient pressure (p = 0.1 MPa). The excess molar volume, VmE, and viscosity deviation, Δη, were calculated from the measured values of density and viscosity. The excess molar volumes of ternary mixtures are negative over the entire mole fraction range and their magnitudes increase with increasing temperature. Viscosity deviations for the ternary mixture are negative over the entire mole fraction range and decrease with increasing temperature. The Cibulka and Redlich–Kister equations were used to correlate the ternary and binary excess molar volumes, respectively.
