Question

Would acetone be a good choice of solvent for a recrystallization experiment?

Answer 1

It would not be my first choice.........

Explanation:

A solvent used for recrystallization ideally offers poor solubility in the cold solvent, but good to middling solubility in the hot solvent. For organic solutes, hexanes and heptane often fulfil these criteria. And obviously, the chemist wants to find something that works. Acetone tends to be a good solvent at all temperatures; stuff will go up in it, and be reluctant to crystallize.

You could layer an acetone solution with hexanes, but there are no guarantees, and you do what works..........and clearly this is the province of experiment.
