: a volatile fragrant flammable liquid ketone C3H6O used chiefly as a solvent and in organic synthesis and found in abnormal quantities in diabetic urine—called also propanone
Simplest and most important ketone (CHCOCH). It is a colourless, flammable liquid, boiling at 133 °F (56.2 °C). Many fats, resins, and organic materials dissolve easily in it, so it is used to make artificial fibres, explosives, resins, paints, inks, cosmetics (including nail-polish remover), coatings, and adhesives. Acetone is used as a chemical intermediate in pharmaceuticals and many other compounds.
