2,4-Dimethyl-3-pentanone was used in an experimental method to measure the equilibrium isotopic fractionation factor (αeq ) for C-bound H positions adjacent to carbonyl group in ketones. | [Uses]
2,4-Dimethyl-3-pentanone is used in an experimental method to measure the equilibrium isotopic fractionation factor (αeq ) for C-bound H positions adjacent to carbonyl group in ketones.It is a carbonyl compound used in an experimental method to measure the equilibrium isotopic fractionation factor (αeq ) for C-bound H positions adjacent to carbonyl group in ketones. Isobutyrone is a very useful synthetic intermediate. It is an intermediate used to prepare α-aryl ketones. It is also used in Grignard reactions. | [Uses]
DiPK has been used in automotive assembly plants as a
ketonic solvent for fuel injectors and as a photoinitiator for
IV-curable acrylic coatings in optical fiber gratings. The U.S.
production ofDnPK was estimated to be,500,000 lb in 2005
according to the 2006 U.S. EPA Inventory Update Reporting
database. | [Definition]
ChEBI: A pentanone that is pentan-3-one substituted by methyl groups at positions 2 and 4 respectively. | [Production Methods]
2,4-Dimethyl-3-pentanone is
preferably obtained by ketonization of isobutyric
acid over a thorium oxide or zirconium oxide
catalyst at 430℃. | [Synthesis Reference(s)]
