2-Decanone was used in the synthesis of:
- brushed block copolymers via conjugation through an acid-labile hydrazone linker to poly(ethylene glycol)-poly(aspartate hydrazide) block copolymers
- methyl ketones
Verwenden
2-Decanone was used in the synthesis of brushed block copolymers via conjugation through an acid-labile hydrazone linker to poly(ethylene glycol)-poly(aspartate hydrazide) block copolymers; methyl ketones. 2-decanone is used as a solvent and an intermediate in synthesising pharmaceuticals and agrochemicals. 2-Decanone has very interesting effects, along with Oakmoss, one of the few materials sufficiently effective as a fixative for ketone. The well-known and highly appreciated topnotes of good quality Oakmoss are enhanced and beautified by small amounts of this ketone. It also finds limited application in flavours, particularly in imitation Coconut and Banana, where its dry-fruity character lends desirable notes.
Vorbereitung Methode
2-Decanone is produced (many methods), e. g., by heating vapors of Nonoic acid and Acetic acid over Thorium oxide at 425° C. Also, by hydrogenation of Heptylideneacetone.
Definition
ChEBI: A methyl ketone that is decane in which the methylene hydrogens at position 2 are replaced by an oxo group.
Aroma threshold values
Medium-type strength odor, orange floral.
Allgemeine Beschreibung
2-Decanone is a constituent of the essential oil of Ruta chalepensis L., which is used in the production of food, drugs and perfumery.
Sicherheitsprofil
Slightly toxic by ingestion. Aflammable liquid. When heated to decomposition it emitsacrid smoke and irritating vapors.
