2,4-Dimethyl-3-pentanone Chemical Properties,Uses,Production
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
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.
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.
Purification Methods
Dry the ketone with CaSO4, shake it with chromatographic alumina and fractionally distil it from P2O5 under N2. [Beilstein 1 IV 3334.]
