Ionic liquid is a significant new media and one of the most compelling solvents mentioned in many fields. It is clear that the introduction of ether or allyl group has the advantages of low viscosity and wide application. In this work, [C1OC2pyrr][DCA], [C1OC2pyrr][NTf2] and [Amim][NTf2] were synthesized and characterized. The d., surface tension, and refractive index of the three ionic liquids and their binary systems with acetonitrile were investigated across a complete composition range. The thermal expansion coefficient (αEp), excess molar volumes (VE), and refractive index deviations (ΔnD) are also calculated The αEp and VE are all neg. while the ΔnD are found pos. in the entire concentration range, indicating the presence of strong interactions between ionic liquids and acetonitrile. The properties are fitted to a Redlich-Kister equation and the results have been interpreted in terms of H-bonding interaction and structural effect, at the same time, the corresponding IR spectra are also carried out. The molar refraction and the molar polarizability calculated which suggest that the existent interactions between ionic liquids and acetonitrile are ion-dipole interactions. The molar Gibbs free energy can be measured and explained properly by the improved Eotvos equation. And the molar surface enthalpy also can be gained and is a temperature-independent constant
