Separating Ethyl Acetate and N-propyl acetate
« on: April 27, 2019, 11:02:58 PM »
Hello Everyone!

In our factory, we have been using a distiller with a vaccum in order to extract solvents from different liquids. This extracted solvent has a mixture of 54% Ethyl Acetate, 42% N-propyl Acetate and 4% other liquids.

We found that Ethyl Acetate has a boiling point of 77.1°C while N-propyl Acetate's boiling point is 101.5°C. We figured that we might be able to separate the two liquids using the distiller at temperatures between 80-90°C but unable to do so. We would like to ask if there is a better way of separating the two in order to get 100% ETAC and 100% NPAC, or at least close to 100%.

I would like to apologize as none of the people here including me are chemists, and I am unsure if this is the correct forum to ask this.

The both components build an zeotropic mixture and are not able to seperate with destillation.



Probably you can find an entrainer.
