Abstract

In the present work, the saturated liquid and vapor densities of normal heptane are investigated based on a previously formulated global equation of state in the vicinity of the critical point. In particular, a crossover thermodynamic potential is used to represent accurately the liquid and the vapor experimental data of normal heptane reported by Abdulagatov and co-workers and those measured by Artyukhovskaya and coworkers as well as for information purposes for those generated from NIST REFPROP package.
