Abstract: New representative reference equations for the thermal conductivity of n-heptane are expressed based on experimental data that has been critically assessed for consistency and for agreement with theory. A large part of the data was collected by the transient hot wire method. The theoretically expected enhancement in the critical region agrees with the data collected and can be well represented by theoretically based equations containing just one adjustable parameter. The correlations presented are applicable from the triple point to 600 K and 250 MPa. The uncertainty for most of the correlation is estimated to be less than 4%.
