Thermal Conductivity of Toluene+Cyclopentane Mixtures: Measurements and Prediction

New measurements of the thermal conductivity of toluene, cyclopentane, and a binary mixture of 60 wt0 toluene are preseInted. The measurements cover the temperature range from 235 to 345 K and from the saturation line up to 20 MPa pressure. The measurements were performed with a transient hot-wire instrument. The uncertainty of the measurements is estimated to be \0.50. The present results are employed to examine the predictive power of a theoreti- cally based scheme for the calculation of the transport properties of mixtures.
