چكيده لاتين :
Perturbed-chain statistical associating fluid theory (PC-SAFT) is used to obtain pure compound parameters of
monoethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and 1,2 propylene glycol. These
parameters are used to calculate the vapor pressures and saturated liquid densities of glycols. The heat of vaporization
and liquid heat capacities for the glycols are also predicted satisfactorily. However, PC-SAFT is not predictive for all
the caloric properties of monoethylene glycol, triethylene glycol and 1,2 propylene glycol.
