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)
3-Pentanone (also known as diethyl ketone) is a simple, symmetrical dialkyl ketone. It is a colorless liquid ketone with an odor like that of acetone . It is soluble in about 25 parts water, but miscible with organic solvents.
Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
In organic chemistry, enols are a type of Functional group or intermediate in organic chemistry containing a group with the formula C=C(OH) (R = many substituents). The term enol is an abbreviation of alkenol, a portmanteau deriving from "-ene"/"alkene" and the "-ol".
At laboratory scale, MIBK can be produced via a three-step process using acetone as the starting material. Self-condensation, a type of aldol reaction, produces diacetone alcohol, [3] which readily dehydrates to give 4-methylpent-3-en-2-one (commonly, mesityl oxide). [4] Mesityl oxide is then hydrogenated to give MIBK. [5]
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.
Pentanal undergoes the reactions characteristic of any alkyl aldehyde, i.e., oxidations, condensations, and reductions. 2-Octanone, produced for use in the fragrance industry, is obtained by the condensation of acetone and pentanal, followed by hydrogenation of the alkene.
In another major industrial process, cyclohexanol is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: [24] 2 C 6 H 12 + O 2 → 2 C 6 H 11 OH This process coforms cyclohexanone , and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid , used to make nylon .
