Measurement of the Thermal Conductivities of Toluene, Cyclohexane, and Diethyl Ether at Pressures up to 15.1 MPa and Their Binary Mixtures at Pressures 0.1 and 10.1 MPa from 291 to 351 K

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.
