A series of 1-octyl-3-propanenitrile imidazolium based room temperature ionic liquids incorporated with different sulfonate-based anions were synthesized and characterized using H-1 NMR, Fourier transform infrared spectroscopy (FTIR), and elemental analysis. The density and viscosity were measured at T = (293.15 to 353.15) K, the refractive index was measured at T (298.15 to 383.15) K, and the thermal expansion coefficient was estimated from the density values. The effects of the anions on these physical properties and on the lattice energy were discussed.
