Statistical Associating Fluid Theory Equation of State with Lennard-Jones Reference Applied to Pure and Binary <i>n</i>-Alkane Systems

Abstract

A prototype equation of state, developed on the basis of thermodynamic perturbation theory of the first order (TPT1), using the Lennard-Jones potential for the reference fluid, is found to represent pure-fluid and binary phase equilibria in the systems of small chain molecules, such as normal alkanes.
