Mesityl oxide is a α,β-Unsaturated 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 as a solvent and in the production of methyl isobutyl ketone.
