Mesityl oxide is a ketone with the formula CH3C(O)CH=C(CH3)2. This compound is a colorless, volatile liquid with a strong peppermint odor.
Synthesis
It is prepared by the condensation of acetone to give diacetone alcohol, which readily dehydrates to give this compound. This type of reaction is called aldol reaction.
A further condensation yields isophorone, which is also used as solvent.
Uses
Mesityl oxide is used a solvent and in the production of methyl isobutyl ketone.
