Description |
Acetone is a flammable, colorless liquid with a pleasant odor. It is used widely as an organic solvent and in the chemical industry. It is the simplest ketone, which also goes by the name dimethyl ketone (DMK). Acetone was originally referred to as pyroacetic spirit because it was obtained from the destructive distillation of acetates and acetic acid. |
|
Chemical Properties |
Acetone, CH3COCH3, also known as 2-propanone and dimethylketone, is a colorless, volatile,flammable liquid that boils at 56°C (133 OF). It is misciblewith water and is oftenused as a solventin the manufacture of lacquers and paints. |
|
Physical properties |
Clear, colorless, liquid with a sweet, fragrant odor. Sweetish taste. Odor threshold concentrations ranged from 42 ppmv (Nagata and Takeuchi, 1990) to 100 ppmv (Leonardos et al., 1969). Experimentally determined detection and recognition odor threshold concentrations were 48 mg/m3 (20 ppmv) and 78 mg/m3 (33 ppmv), respectively (Hellman and Small, 1974). |
|
Uses |
Acetone is used in the manufacture of a largenumber of compounds, such as acetic acid,chloroform, mesityl oxide, and MIBK; in themanufacture of rayon, photographic films,and explosives; as a common solvent; inpaint and varnish removers; and for purifyingparaffins. |
