Abstract

A UNIFAC group contribution method with an explicit temperature dependent free volume term has been developed. The systems used in the development were benzene-polyethylene oxide from 319 to 423 K and n-hexane-n-hexadecane from 303 to 333K. The addition of temperature dependence to the proportionality factor in the free volume expression decreased the average error in prediction of the solvent activities from 15% to 6%. © 1987 Plenum Publishing Corporation.
