2,4-Dimethyl-3-pentanone Usage And Synthesis

Chemical Properties

2,4-Dimethyl-3-pentanone is a colorless liquid with a characteristic odor similar to that of camphor; it is insoluble in water but soluble in organic solvents.

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.

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

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.

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℃.

Definition

ChEBI: 2,4-dimethyl-3-pentanone is a pentanone that is pentan-3-one substituted by methyl groups at positions 2 and 4 respectively. It has a role as a metabolite. It is functionally related to a pentan-3-one.

Tetrahedron Letters, 24, p. 4207, 1983 DOI: 10.1016/S0040-4039(00)88301-X

Purification Methods

Dry the ketone with CaSO4, shake it with chromatographic alumina and fractionally distil it from P2O5 under N2. [Beilstein 1 IV 3334.]
