5. SAT-EOS: Liquid-vapor coexistence properties

Liquid-vapor coexistence properties as determined from an empirical fit of a large amount of simulation data. The data serve as an approximate guide for liquid-vapor coexistence properties at temperatures other than those investigated in Item 3. Furthermore, the empirical fit should not be used in the vicinity of the critical point.

Liquid-vapor coexistence as predicted by an empirical equation of state by Johnson and co-workers [1]. The parameters for this EOS were fitted to a large amount of simulation data. The data should only serve as an approximate guide for liquid-vapor coexistence properties. Furthermore, the empirical fit should not be used in the vicinity of the critical point.
