GENERAL EQUATION FOR CORRELATING THE THERMOPHYSICAL PROPERTIES OF N-PARAFFINS, N-OLEFINS, AND OTHER HOMOLOGOUS SERIES .2. ASYMPTOTIC-BEHAVIOR CORRELATIONS FOR PVT PROPERTIES

In this second in a series of three papers, asymptotic behavior correl ations (ABCs) are presented for PVT-related properties: normal boiling and melting point, critical temperature, pressure, and volume, acentr ic factor, liquid molar volume, and vapor pressure. The theoretical ba sis for the 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. Th ey are preferable to existing correlations in most instances. For melt ing point and liquid density, comparisons are made with high molecular weight, linear polyethylenes. It is also demonstrated that the ABCs d eveloped for n-paraffins and n-olefins can be used to estimate the pro perties of other higher carbon-number n-alkyl derivatives, if the prop erties are known for at least one lower carbon-number member of the ho mologous series.
