Isophorone is an organic compound, a colorless to yellowish liquid with characteristic smell, that is used as a solvent and as an intermediate in organic synthesis. Isophorone also occurs naturally in cranberries.
Isophorone can be manufactured by catalyzed self-condensation of acetone. Mesityl oxide is the initial product of the self-aldol condensation of acetone. The acetone formed can react further with mesityl oxide via a Michael reaction and subsequent intramolecular aldol condensation to eventually obtain the six-membered ring of isophorone. This is an example of the Robinson annulation. The yield of the two compounds depends on the reaction conditions.
Isophorone is used as a solvent in some printing inks, paints, lacquers, adhesives, copolymers, coatings, finishings and pesticides. It is also used as a chemical intermediate and as an ingredient in wood preservatives and floor sealants.
