3,3-Dimethylacrylic acid Usage And Synthesis
- DescriptionMay be prepared by the action of alkalis or bases on the ester of α-bromoisovaleric acid; by condensation of acetone with malonic acid or bromoacetic ester; by oxidation of mesityl oxide with sodium hypochlorite.
- Chemical Properties3-Methylcrotonic acid has green, phenolic, dairy aroma
- Chemical PropertiesWhite to brown crystal
- OccurrenceReported found in the rhizomes of Senecio kaempferi Seib.; the corresponding ester occurs naturally in waste wort. Also reported found in raspberries, wheat bread, cocoa, coffee, black tea, Arctic bramble, and green and roasted maté.
- DefinitionChEBI: A methyl-branched fatty acid that is but-2-enoic acid bearing a methyl substituent at position 3.
- PreparationBy the action of alkalis or bases on the ester of α-bromoisovaleric acid; by condensation of acetone with malonic acid or bromoacetic ester; by oxidation of mesityl oxide with sodium hypochlorite.
- Purification MethodsCrystallise the acid from hot water or pet ether (b 60-80o). [Beilstein 2 IV 1555.]
