ESDU 83015 contains liquid thermal conductivity data for sixteen alkyl and alkenyl pyridines@ ten alkyl quinolines@ three alkyl pyrroles@ pyrrolidine and piperidine. Experimental results drawn from the literature for each pure compound were fitted with a four-term polynomial equation in reduced temperature. The coefficients were also faired with changing molecular structure to ensure the best correlation not only for the individual compounds but also for them as members of their chemical series. The coefficient correlations also allowed values to be predicted for those pure compounds for which no measured data exist. The equations were used to tabulate thermal conductivity values at saturation pressure@ from the melting temperature where known or an appropriate starting point@ to about 0.9 of the critical temperature in SI units at 10 K and 10 degree Celsius intervals. The likely uncertainties in the values presented are indicated in the text. The critical temperature@ coefficients and sources of the data are given for each compound. An approximate expression@ valid between the melting and boiling temperatures is given for the effect of pressure up to 50 MPa.
