A General Equation for Correlating the Thermophysical Properties of N-Paraffins, N-Olefins, and Other Homologous Series .3. Asymptotic-Behavior Correlations for Thermal and Transport-Properties
In this final paper of the series, asymptotic behavior correlations (ABCs) are presented for thermal properties (ideal-gas enthalpy and free energy of formation, ideal-gas heat capacity, enthalpy of vaporization, and liquid heat capacity) and for transport properties (liquid viscosity, thermal conductivity, and surface tension). The theoretical basis for asymptotic behavior of these properties is discussed. The correlations were developed using literature data for n-paraffins and n-olefins (1-alkenes) and give accurate and consistent predictions. They are preferable to existing correlations in most instances. For specific heat, viscosity, thermal conductivity, and surface tension, comparisons are made with high molecular weight, linear polyethylenes and other long-chain molecules.
