Thermophysical properties of 1-butyl-3-methylimidazoliumtris(pentafluoroethyl) trifluorophosphate, [C4mim][(C2F5)3PF3] (CAS RN 917762-91-5) ionic liquid, were measured in the temperature range T = (283.15–353.15) K, at P = 0.1 MPa. These properties include density, isobaric heat capacity, speed of sound, refractive index, viscosity, and thermal conductivity and their correlation as a function of temperature. Data obtained were compared with the available literature, whenever available. Comparison of these results with those reported for ILs with the same cation or anion is presented and discussed. Derived quantities such as isobaric expansivity and isothermal and isentropic compressibility were also estimated. Arrhenius, Ghatee, Vogel–Fulcher–Tammann, and IUPAC equations were applied to correlate viscosity data dependence on temperature, the last one being more effective and accurate. An estimation method for thermal conductivity of ILs was applied. Calculated values by this equation deviate from the experimental data between −15.6% at 293 K and −17.9% at 353 K, within the mutual uncertainty of these data and estimation. The thermal conductivity of the IoNanofluid made from the dispersion of multi-walled carbon nanotubes (1% wt MWCNTs) in [C4mim][(C2F5)3PF3] was determined. The enhancement in thermal conductivity due to the presence of MWCNTs was found to vary between 4% at 293 K and 9.6% at 353 K, an average of 6.2%, weakly dependent on temperature.

在温度范围T下测量了[C 4 mim] [（C 2 F 5）3 PF 3 ]（CAS RN 917762-91-5）离子液体的1-丁基-3-甲基咪唑鎓三（五氟乙基）三氟磷酸酯的热物理性质。=（283.15–353.15）K，在P＝ 0.1MPa。这些特性包括密度，等压热容，声速，折射率，粘度和导热率，以及它们与温度的关系。尽可能将获得的数据与现有文献进行比较。这些结果与报告的具有相同阳离子或阴离子的IL的结果进行了比较和讨论。还估算了诸如等压膨胀性，等温和等熵可压缩性的派生量。使用Arrhenius，Ghatee，Vogel-Fulcher-Tammann和IUPAC方程来关联粘度数据对温度的依赖性，最后一个更为有效和准确。采用了ILs导热系数的估算方法。该公式的计算值与293 K时的-15.6％和353 K时的-17.9％之间的实验数据有所不同，在这些数据和估计的相互不确定性范围内。由多壁碳纳米管（1％wt MWCNT）在[C]中的分散体制得的纳米流体的热导率4个MIM] [（C 2 ˚F 5）3 PF 3 ]测定。发现由于存在MWCNTs，导热系数的提高介于293 K时的4％和353 K时的9.6％之间，平均为6.2％，对温度的依赖性很小。
