Process for the separation of ethyl acetate from ethanol and water by extractive distillation |
摘要 |
Ethyl acetate cannot be completely removed from ethanol and water mixtures by distillation because of the presence of the minimum ternary azeotrope. Ethyl acetate can be readily removed from mixtures containing it, ethanol and water by using extractive distillation in which the extractive distillation agent is a higher boiling oxygenated, sulfur containing or nitrogenous organic compound or a mixture of these. Typical examples of effective agents are: 1,4-butanediol; ethylene glycol-1,5-pentanediol; propylene glycol-tetraethylene glycol-polyethylene glycol; glycerine-propylene glycol-tetraethylene glycol-1,4-butanediol.
