R. Agrawal et Ep. Wallis, MOLECULAR SIMULATION OF THE VAPOR-LIQUID-EQUILIBRIUM OF METHANETHIOL PLUS PROPANE MIXTURES, Fluid phase equilibria, 131(1-2), 1997, pp. 51-65
We have used the Gibbs ensemble Monte Carlo (GEMC) method to calculate
the vapor-liquid equilibrium properties for pure propane and methanet
hiol as well as their mixtures. We used two different potential-energy
surfaces to describe the propane and methanethiol molecules. The resu
lts show that the simple site-site potential-energy surfaces work well
for the pure components by optimizing the parameters to reproduce the
liquid-phase density at the normal boiling point. For mixtures, the s
ite-site potential-energy surface predicts the liquid-phase densities
fairly well, but is not accurate enough to give quantitative results f
or the vapor-phase mole fraction for this system. (C) 1997 Elsevier Sc
