Descriptions

Prediction of activity coefficients at infinite dilution γ 1∞ has been attempted based on a modified Wilson equation (GC-MW) proposed in this study from knowledges of molecular structures and pure-component physical properties. Alkane (1) in alkanol or alkanediol (2) solvent and alkanol (1) in alkane (2) solvent have been studied and it is noted that prediction performances of GC-MW for these solutes are fairly good and better than those of UNIFAC (Dortmund).
