Methylethyl ketone oxime is the organic compound with the formula C 2 H 5 C(NOH)CH 3. This colourless liquid is the oxime derivative of methyl ethyl ketone . MEKO , as it is called in the paint industry, is used to suppress "skinning" of paints: the formation of a skin on paint before it is used.
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 .
In terms of scale, the most important ketones are acetone, methylethyl ketone, and cyclohexanone. [23] They are also common in biochemistry, but less so than in organic chemistry in general. The combustion of hydrocarbons is an uncontrolled oxidation process that gives ketones as well as many other types of compounds.
Methyl ethyl ketone peroxide (MEKP) is an organic peroxide with the formula [(CH 3)(C 2 H 5)C(O 2 H)] 2 O 2. MEKP is a colorless oily liquid. It is widely used in vulcanization (crosslinking) of polymers. [3] It is derived from the reaction of methyl ethyl ketone and hydrogen peroxide under acidic conditions.
Examples are the reaction of ethyl acetoacetate and sodium nitrite in acetic acid, [4] [5] the reaction of methyl ethyl ketone with ethyl nitrite in hydrochloric acid. [6] and a similar reaction with propiophenone, [7] the reaction of phenacyl chloride, [8] the reaction of malononitrile with sodium nitrite in acetic acid [9]
A number of blocking agents maybe employed but a common one is Methylethyl ketone oxime (MEKO). Caprolactam is also used. [8]When blocked, there is no isocyanate (NCO) functionality, so it is much easier to disperse the species in water if the desire is to produce waterborne resins.
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.
Methyl ethyl ketone peroxide, benzoyl peroxide and to a smaller degree acetone peroxide are used as initiators for radical polymerization of some thermosets, e.g. unsaturated polyester and vinyl ester resins, often encountered when making fiberglass or carbon fiber composites (CFRP), with examples including boats, RV units, bath tubs, pools ...
