New experimental data on the thermal conductivity of liquid halogenated ethanes, R112 (CCl/sub 2/F-CCl/sub 2/F), R113 (CCl/sub 2/F-CClF/sub 2/), R114 (CClF/sub 2/-CClF/sub 2/), R114B2 (CBrF/sub 2/-CBrF/sub 2/), and R123 (CHCl/sub 2/-CF/sub 3/), are presented in the temperature range from 283 to 348 K at pressures up to 200 MPa or the freezing pressures. The measurements were carried out by a transient hot-wire apparatus within an uncertainty of +/- 1.0%. The thermal conductivity data obtained have been analyzed by means of the corresponding-states principle and other empirical methods. It is found that the corresponding-states correlation lambda = f(T/sub r/, P/sub r/) holds well for R112, R113, and R114. The thermal conductivity can also be correlated satisfactorily with temperature, pressure, and molar volume by a similar expression to the Tait equation and the dense hard-sphere model presented by Dymond.
