A number of solvents for separation of ethyl acetate-ethanol were examined in a VLE experiment apparatus.The integrated properties of the solvents were investigated and the experimental data were correlated with the modified UNIFAC model. It was found from the results that binary mixed solvents (DMSO+DMF) were superior to single solvent (DMSO or DMF) for separating ethyl acetate-ethanol by extractive distillation.The modified UNIFAC model combined with experiments is a rapid
accurate approach to selecting the solvent for extractive distillation.
