| Abstract: | A rapid and accurate approach for selection of solvent for extractive distillation is presented. The candidate solvents are generated by using UNIFAC & Solubility Parameter Model and tested with headspace gas chromatography. The approach enlarges the size of the possible search space and improves reliability of the result. N - methylpyrrolidone, γ - butyrolactone are found to be appropriate solvents for cyclohexane - cyclohexene- benzene separation by extractive distillation, and are superior to N, N - dimethylacetamide, adiponitrile introduced in the literature |
