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]
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 ...
[6] [5] Originally the process used acetone instead of methyl ethyl ketone. [6] Methyl ethyl ketone is advantageous because the resulting ketazine is immiscible in the reaction mixture and can be separated by decantation. [2] [7] The world's largest hydrazine hydrate plant is in Lannemezan in France, producing 17,000 tonnes of hydrazine ...
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.
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002). The list can be found as an appendix to 40 CFR 355 . [ 1 ]
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' are methyl), with the formula (CH 3) 2 CO ...
