Speration of organic liquids
There is a mixture of Butyraldehyde (also known as butanal) and ethanoic acid in a bottle. How can you obtain the pure form of the two Compounds (ie no aq. state) using a separatory funnel?

I got Dysgraphia and i am not living in the US so plz forgive my poor english.

I say the answer is, do your own homework Tongue

Theism is to believe what other people claim, Atheism is to ask "why should I".

Really difficult, as butanal is soluble in acetone.. best bet would be distillation.. do they form an azeotrope?

Hey that is not homework. It is A-level a past paper question and I lost the answer key.

Actually.. thinking on it a bit, the densities are significantly different enough to allow it to sit in the funnel and drain off the ethanoic acid from the bottom of the funnel..

This will not give you pure compounds, but knowing that its from an A-level paper gives me enough information to say this would probably be the suggested answer.
