(prō`pənōn), CH3COCH3, colorless, flammable liquid. Acetone melts at −94.8°C; and boils at 56.2°C;. It is the simplest aliphatic ketoneketone
, any of a class of organic compounds that contain the carbonyl group, C=O, and in which the carbonyl group is bonded only to carbon atoms. The general formula for a ketone is RCOR′, where R and R′ are alkyl or aryl groups.

. Acetone is widely used in industry as a solvent for numerous organic substances and is a component of most paint and varnish removers. It is used in the manufacture of synthetic resins and fillers, smokeless powders (e.g., cordite), and numerous other organic compounds. Acetone is produced commercially chiefly by catalytic dehydrogenation of isopropanol.
