Methyl isobutyl ketone (MIBK, 4-methylpentan-2-one) is an organic compound with the condensed chemical formula (CH 3) 2 CHCH 2 C(O)CH 3. This ketone is a colourless liquid that is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose.
Mesityl oxide is used as a solvent and in the production of methyl isobutyl ketone by hydrogenation: [5] Further hydrogenation gives 4-methyl-2-pentanol (methyl isobutyl carbinol). Dimedone is another established use of mesityl oxide.
Butanone, also known as methyl ethyl ketone (MEK) or ethyl methyl ketone, [a] is an organic compound with the formula CH 3 C(O)CH 2 CH 3. 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. [7]

In organic chemistry, a ketone / ˈ k iː t oʊ n / is an organic compound with the structure R−C(=O)−R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group −C(=O)− (a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' is methyl), with the formula (CH 3) 2 CO ...
Hexanone may refer to the following ketones containing six carbon atoms: 2-Hexanone (Methyl butyl ketone, MBK) 4-Methyl-2-pentanone (Methyl isobutyl ketone, MIBK) 3-Methyl-2-pentanone (Methyl sec-butyl ketone) 3,3-Dimethyl-2-butanone (Methyl tert-butyl ketone, Pinacolone) 3-Hexanone (Ethyl propyl ketone) 2-Methyl-3-pentanone (Ethyl isopropyl ...
