摘要：
离子液体已被证明是优异的传热流体，可替代工业中用于换热器和其他传热设备的常用HTF。然而，其工业化应用取决于每千克产品的生产成本，以使其在工业应用中能够与联苯和二苯醚、烷基化芳烃以及二甲基聚硅氧烷油竞争；这些物质在200 °C以上会降解，并存在一定环境问题。传热流体的效率取决于影响对流传热的基本热物理性质（密度、热容、热导率和黏度），因为这些性质是计算不同换热器几何形状传热系数所必需的。在第1部分中，介绍了由BASF生产、商品名为Basionics ST35的纯1-乙基-3-甲基咪唑甲磺酸盐$[C_{2}mim][CH_{3}SO_{3}]$（CAS号145022-45-3，ECOENG 110）在略低于室温至355 K温度范围内的热物理性质；其纯度测定值≥97%，水含量≤0.5%，氯化物（$Cl^{-}$）含量≤2%。在本文中，我们报道了在$P$=0.1 MPa下、整个浓度范围内[C2mim][CH3SO3]与水混合物的热物理性质。所测量的性质包括密度和声速（293.15 < $T$/K < 343.15）、黏度、电导率和热导率、折射率（293.15 < $T$/K < 353.15），以及该离子液体在水中的无限稀释扩散系数（298.15 K）。
英文摘要：
Ionic liquids have proved to be excellent heat transfer fluids and alternatives to common HTFs used in industries for heat exchangers and other heat transfer equipment. However, its industrial utilization depends on the cost per kg of its production, to be competitive for industrial applications with biphenyl and diphenyl oxide, alkylated aromatics, and dimethyl polysiloxane oils, which degrade above 200 °C and possess some environmental problems. The efficiency of a heat transfer fluid depends on the fundamental thermophysical properties influencing convective heat transfer (density, heat capacity, thermal conductivity, and viscosity), as these properties are necessary to calculate the heat transfer coefficients for different heat exchanger geometries. In Part 1, the thermophysical properties of pure 1-ethyl-3-methylimidazolium methanesulfonate $[C_{2}mim][CH_{3}SO_{3}]$ (CAS no. 145022-45-3), (ECOENG 110), produced by BASF, under the trade name of Basionics ST35, with an assay $\geq$97% with $\leq$0.5% water and $\leq$2% chloride ($Cl^{-}$), were presented, for temperatures slightly below room temperature and up to 355 K. In this paper, we report the thermophysical properties of mixtures of [C2mim][CH3SO3] with water, in the whole concentration range, at $P$ = 0.1 MPa. The properties measured were density and speed of sound (293.15 < $T$/K < 343.15), viscosity, electrical and thermal conductivities, refractive index (293.15 < $T$/K < 353.15), and infinite dilution diffusion coefficient of the ionic liquid in water (298.15 K).
