ABSTRACT
Densities q, speeds of sound u, and refractive indices nD were measured from T = (278.15 to 343.15) K. Dynamic viscosities g were measured from T = (293.15 to 323.15) K. Surface tensions r were determined from T = (288.15 to 313.15) K. The physical properties data were measured at atmospheric pressure. The coefficients of thermal expansion ap of the ionic liquids were calculated from the experimental values of the density at several temperatures. The Parachor method was used to predict the densities, the refractive indices, and the surface tensions of the ionic liquids, and a comparison between experimental and predictive values was made at T = 298.15 K.
