2-Pentanone or methyl propyl ketone (MPK) is a ketone and solvent of minor importance. It is comparable to methyl ethyl ketone , but has a lower solvency and is more expensive. [ 5 ] It occurs naturally in Nicotiana tabacum (Tobacco) [ 6 ] and blue cheese as a metabolic product of Penicillium mold growth.
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.
Pentanone may refer to the following ketones containing five carbon atoms: 2-Pentanone (Methyl propyl ketone, MPK) 3-Methyl-2-butanone (Methyl isopropyl ketone, MIPK)
LiHMDS is often used in organic chemistry as a strong non-nucleophilic base. [3] Its conjugate acid has a pK a of ~26, [4] making it is less basic than other lithium bases, such as LDA (pK a of conjugate acid ~36).
Perfluoro(2-methyl-3-pentanone) is a fluorinated ketone with the structural formula CF 3 CF 2 C(=O)CF(CF 3) 2, a fully-fluorinated analog of ethyl isopropyl ketone. It is used as an electronics coolant liquid and fire protection fluid sold commercially by 3M under brand names such as Novec 1230 , Novec 649 , and FK-5-1-12 .
Three of these alcohols, 2-methyl-1-butanol, 2-pentanol, and 3-methyl-2-butanol (methyl isopropyl carbinol), contain stereocenters, and are therefore chiral and optically active. The most important amyl alcohol is isoamyl alcohol , the chief one generated by fermentation in the production of alcoholic beverages and a constituent of fusel oil .
2-Cyclopentenone is the organic compound with the chemical formula (CH 2) 2 (CH) 2 CO. 2-Cyclopentenone contains two functional groups, a ketone and an alkene. It is a colorless liquid. Its isomer, 3-cyclopentenone is less commonly encountered.
AMPS is made by the Ritter reaction of acrylonitrile and isobutylene in the presence of sulfuric acid and water. [2] The recent patent literature [3] describes batch and continuous processes that produce AMPS in high purity (to 99.7%) and improved yield (up to 89%, based on isobutene) with the addition of liquid isobutene to an acrylonitrile / sulfuric acid / phosphoric acid mixture at 40°C.
