butanone
methyl ethyl ketone , MEK (skrót)

Oxidation of 2-butanol is one way to produce butanone.

In the case of solution-based processing, typical solvents used include dimethylformamide as well as the more volatile butanone.

As butanone dissolves polystyrene, it is sold as "model cement" for use in connecting together parts of scale model kits.

Side-products may also form, including butanone, ethyl acetate, formic acid, and propionic acid.

The experiment succeeded with the trained perfumers used as subjects, who perceived that a mixture of 60% butanone and 40% mint carvone smelled like caraway.

Dimethylglyoxime can be prepared from butanone first by reaction with ethyl nitrite followed by sodium hydroxylamine monosulfonate:

Emissions of butanone will continue to be regulated as a volatile organic compound because of its contribution to the formation of tropospheric (ground-level) ozone.

For example, butanone is significantly soluble in water, but these two solvents are not miscible because they are not soluble in all proportions.

In 2005, the U. S. Environmental Protection Agency removed butanone from the list of hazardous air pollutants (HAPs).

Viable ketones were butanone, triacetylmethane (TAM), 2,3-pentanedione (2,3-PD), and acetylacetone; all of which can stabilize radical formation through resonance.

Later developments of the process replace the acetone with butanone (methyl ethyl ketone): the basic chemistry remains the same, but the butanone azine is immiscible in the reaction mixture, and can be separated by decantation.

Values of Θ and ψ 1, in table 8.1, show that for systems 1 to 4 the entropy parameter is positive, as expected, but for poly (acrylic acid) in dioxan and polymethacrylonitrile in butanone, ψ is negative at the theta temperature.
