Estimation PC-SAFT equation of state parameters of ethanol, 1-propanol, 1-butanol and 1-nonanol

This work reports new estimation of PC-SAFT equation of state parameters of ethanol, 1-propanol, 1-butanol, 1-nonanol. This parameters are obtained by fitting experimental vapor pressure and liquid density data from 298.15 K to 494.5 K. The estimated parameters are used to validate the experimental density data found in literarture. In this work, we predict the density of alcohols at high pressure and hight temperature.
