Problems with extractive distillation of ethyl acetate
Thread Content
What is the extractant chosen for the extraction of ethyl acetate and water during distillation? Can ethylene glycol be used? Should ethyl acetate be the product at the top of the tower? Many sources seem to indicate that the boiling point of water-ester azeotropes is lower. Wouldn’t that mean the azeotrope forms on top?
A simpler method is heterogeneous azeotropic distillation. If extractive distillation is to be used, it is recommended to try DMSO
I’m also seeking an answer to this question; thank you all
I thought about it and more or less understood it, but I’m not sure if it’s correct. Ethylene glycol as an extractant should be added to enable mixing of ethylene glycol with ethanol. It increased the relative volatility of ethanol and ethyl acetate. Ethyl acetate, with a boiling point of 78 degrees, is distilled off from the top of the tower. Ethanol and ethylene glycol remain at the bottom of the tower.
Ethanol and ethyl acetate can form a ternary azeotrope with water, while ethanol and ethyl acetate can form a binary azeotrope. Additionally, your question is not clear enough; I’m not sure what you want to do
It is to separate ethanol, ethyl acetate, and water using extractive distillation. Ethylene glycol was used as an extractant to separate ethyl acetate. Then, another packed tower is used to separate ethylene glycol from water.
Azeotropic distillation will suffice; extractive distillation is not recommended
Azeotropic distillation? I believe there is information available on the use of extractive distillation for separation in industry
I see that there’s no ethanol mentioned in your question? Did I missee it?
