| titleOfInvention | Separation of isopropanol from isopropyl acetate by extractive distillation |
| abstract | Isopropanol cannot be completely removed from isopropanol-isopropyl acetate-water mixtures by distillation because of the presence of the minimum ternary azeotrope. Isopropanol can be readily removed from mixtures containing it, isopropyl acetate and water by using extractive distillation in which the extractive agent is a higher boiling ester of phthalic acid. Typical examples of effective agents are diethyl phthalate, diisooctyl phthalate and methyl benzoate, dibutyl phthalate, methyl benzoate and nitromethane. |
