In this work, the thermal conductivities of toluene, cyclohexane, and diethyl ether were measured from 291 to 351 K at pressures up to 15.1 MPa. The binary systems of toluene–cyclohexane, toluene–diethyl ether, and cyclohexane–diethyl ether were also measured from 291 to 351 K at pressures 0.1 and 10.1 MPa. The relative expanded uncertainty of the obtained data was estimated to be ±2% with a confidence level of 0.95 (k = 2). The linear thermal conductivity model was used to correlate the pure components as a function of temperature and pressure. The thermal conductivities of binary systems were fitted as a function of temperature and composition. For pure components, the maximum values of absolute percentage deviation (AAD) and maximum absolute percentage deviation (MAD) are 0.45 and 0.87%, respectively. For binary systems, the maximum values of AAD and MAD are 0.56 and 1.79%, respectively.

甲苯、环己烷和二乙醚在压力高达 15.1 MPa 及其二元混合物在压力 0.1 和 10.1 MPa 下从 291 到 351 K 的热导率的测量

在这项工作中，在高达 15.1 MPa 的压力下测量了甲苯、环己烷和乙醚的热导率从 291 到 351 K。甲苯-环己烷、甲苯-乙醚和环己烷-乙醚的二元系统也在 0.1 和 10.1 MPa 的压力下从 291 到 351 K 测量。所得数据的相对扩展不确定性估计为±2%，置信水平为 0.95 ( k= 2)。线性热导率模型用于将纯组分关联为温度和压力的函数。二元系统的热导率被拟合为温度和成分的函数。对于纯组分，绝对百分比偏差 (AAD) 和最大绝对百分比偏差 (MAD) 的最大值分别为 0.45 和 0.87%。对于二元系统，AAD 和 MAD 的最大值分别为 0.56% 和 1.79%。
