ABSTRACT
Isothermal vapor-liquid equilibrium data for binary systems of propane with methanol and ethanol were measured from 313.55 K to 349.78 K and from 0.3 MPa to 2.8 MPa. A circulating-type apparatus with a view cell was used. The measured data show highly nonideal behavior due to their associating tendency of alcohols, and these make them difficult to correlate reliably with classical theories. The data were correlated with sufficient accuracy by using the equation of state proposed earlier by the authors.
