Mar 02, 2020 The answer is “YES”. A rotary evaporator can remove solvent by evaporating samples through the continuous rotation of the evaporation flask. Meanwhile, the evaporation flask is heated uniformly by a water bath. Then the material with a lower boiling point can be evaporated quickly under negative pressure.

Nov 05, 2017 Treatment with bases does not remove solventy smell - there are solventy smells besides ethyl acetate. Acetaldehyde has BP 20C, so it is likely to evaporate preferentially. Ethyl acetate has BP 1C away from ethanol, so it is less likely. Since I have a bottle that I know contains only ethyl acetate, I'm happy to run that test.

Oct 11, 2014 Ethyl acetate’s flavor varies from a light pear-like character to solvent-like in high concentrations. Once it is in your alcohol it is very difficult to remove. Your best bet is to work with your yeast to produce less of it and or remove it for you when it is done making your ethoanol. Here are some suggestions that I have found.
