摘要

根据相应态理论，临界体积、临界温度与压力的关系Tc / Pc和产物PcVc2与同源链中的碳数呈线性关系。这表明加性和本构性质适合于状态方程的构造。本文提出了Soave-Redlich-Kwong型的状态方程:由于它的本构参数中包含了空速(p / s)和摩尔折射(r / m)，所以是一个加性和本构的状态方程。用正构烷烃的同源系列来说明所提方程的适用性。

ACEOS – The additive and constitutive equation of state in the n-alkane homologous series

The critical volume $V_{c}$ , the relation between the critical temperature and the pressure T_c / P_c and the product $P_{c} V_{c}^{2}$ depend linearly on the number of carbons in a homologous series as a consequence of the theory of corresponding states. This suggests that additive and constitutive properties are suitable for the construction of equations of state. In this article, an equation of state of Soave–Redlich–Kwong type is proposed: an additive and constitutive equation of state because it contains among its constitutive parameters the parachor $(℘_{c h})$ and the molar refraction $(R_{m})$ . The homologous series of the n-alkanes is used to illustrate the applicability of the proposed equation.
