Critical properties[edit]

The pressure, temperature and density at the critical point have been calculated for a virial equation of state using the TraPPE-UA force field, and are given in Table I of [1].

Virial coefficients[edit]

The virial coefficients B_2-B_6 as a function of temperature for the TraPPE-UA force field have been tabulated by Schultz and Kofke [2].
