Résumé

Independent synthesis of ionic liquid [emim][Tf2N], and the surface tension, density, viscosity and conductivity are measured in the temperature range of 298.15K~338.15K, 0.1MPa, and under the same condition the literature data were compared. The results of the study show that, surface tension of the ionic liquid decreases with the increases of the length of the cation substituted carbon chain and the anion size. Surface tension and density of ionic liquid [emim][Tf2N] almost linearly change with the temperature. At the same time, the least square method is used to process the experimental data, and the regression equation of surface tension and density with temperature is obtained,and the viscosity decreases with increasing temperature, the conductivity increases with increasing temperature. Determination of these data to fill the ionic liquid [emim][Tf2N] relevant physical parameters blank, and provide a reference for its application.
