Title: Separation of ethyl acetate and ethanol from methyl ethyl ketone and water, and ethyl acetate from ethanol and water by extractive distillation

Abstract

A number of extractive distillation agents were investigated to separate ethyl acetate and ethanol from methyl ethyl ketone and water in an ethyl acetate-ethanol-methyl ethyl ketone-water mixture, and ethyl acetate from ethanol and water in an ethyl acetate-ethanol-water mixture by means of extractive distillation. A measure of separation is the relative volatility, which was calculated by the Fenske equation. The results showed that it is possible to separate the components from these two mixtures by extractive distillation with a distillation column containing relatively few theoretical plates. It was found that the proper extractive distillation agent completely eliminated azeotrope formation among the components in the mixtures investigated. Packed columns can be used in extractive distillation even though they are not quite as efficient as perforated plate columns. For the separation of ethyl acetate and ethanol from methyl ethyl ketone and water one of the more attractive extractive agents is comprised of 25.0 wt.% hydroquinone, 25.0 wt.% ortho-tertbutylphenol, 25.0 wt.% catechol and 25.0 wt.% dimethylformamide, and the relative volatilities of ethnaol to methyl ethyl ketone obtained was 1.51 and ethyl acetate to methyl ethyl ketone was 1.69. For the separation of ethyl acetate from ethanol and water a typical attractive extractive agentmore » is comprised of 33.33 wt.% glycerol, 33.33 wt.% ethylene glycol and 33.33 wt.% triethylene glycol, and the relative volatility of ethyl acetate to ethanol obtained was 3.93.« less
