butanone
Also known as MEK, methylethyl ketone, oxobutane, 3-butanone, methylacetone, C2H5COCH3, methyl(ethyl) ketone, ethyl(methyl) ketone
Butanone, also known as methyl ethyl ketone (MEK) or ethyl methyl ketone, is an organic compound with the formula CH3C(O)CH2CH3. This colorless liquid ketone has a sharp, sweet odor reminiscent of acetone. It is produced industrially on a large scale, but occurs in nature only in trace amounts. It is partially soluble in water, and is commonly used as an industrial solvent. It is an isomer of another solvent, tetrahydrofuran.

==Production== Butanone may be produced by oxidation of 2-butanol. The dehydrogenation of 2-butanol is catalysed by copper, zinc, or bronze: CH3CH(OH)CH2CH3 → CH3C(O)CH2CH3 + H2
