The guidelines to constitute a database containing, for 1800 pure fluids, more than 300,000 pseudo-experimental vapor pressure, liquid density, enthalpy of vaporization, and heat capacity data are described. Such provides tool fair assessment the performances equations state correlate (or predict) properties components. In this paper, we use it assess performance four cubic (CEoSs): original Soave–Redlich–Kwong (SRK), Peng–Robinson (PR), translated-consistent versions PR (tc-PR) RK (tc-RK). deviations between calculated experimental compared CEoSs, which make possible discuss influence ?-function on vapor–liquid equilibrium how volume translation impacts volumetric properties. Eventually, components divided into 1252 non-self-associating 548 self-associating compounds, accuracy CEoSs depending associating character molecules is discussed.
