【Abstract】 An approach was suggested to preliminarily select extractants of alcohol-water systems according to the relation between distribution coefficients and activity of alcohol in solvents . The activity of alcohol in solvents were calculated by the UNIFAC model. The correction of the approach was tested by the data from the literature. Several kinds of extractants of the alcohol-water systems such as phenol, butyric acid etc were predicted .更多还原
