在这第二个系列的三篇论文中，渐近行为相关性（ABC）的PVT相关属性：正常沸点和熔点，临界温度，压力，和体积，偏心因子，液体摩尔体积，和蒸汽压。这些性质的渐近行为的理论基础进行了讨论。正构烷烃和正烯烃（1-烯烃）的文献数据开发的相关性，并给出准确和一致的预测。在大多数情况下，它们比现有的相关性更可取。对于熔点和液体密度，与高分子量线性聚乙烯进行比较。它也表明，ABC开发的正链烷烃和正烯烃可以用来估计其他较高的碳数正烷基衍生物的性能，如果属性是已知的至少一个较低的碳数成员的同源系列。
In this second in a series of three papers, asymptotic behavior correlations (ABCs) are presented for PVT-related properties: normal boiling and melting point, critical temperature, pressure, and volume, acentric factor, liquid molar volume, and vapor pressure. The theoretical basis 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. They are preferable to existing correlations in most instances. For melting point and liquid density, comparisons are made with high molecular weight, linear polyethylenes. It is also demonstrated that the ABCs developed for n-paraffins and n-olefins can be used to estimate the properties of other higher carbon-number n-alkyl derivatives, if the properties are known for at least one lower carbon-number member of the homologous series.
