What is 2-Decanone?

Chemical properties

CLEAR SLIGHTLY YELLOW LIQUID

Chemical properties

Colorless clear liquid.

Occurrence

Reported found in rue oil China (1.31%), rue flower oil Colombia (1.25%), rue oil Cuba (0.72%), ambrette seed oil (0.10%), Croton flavens L. (Welensali) leaf oil Curacao (0.10%), cascarilla bark oil (0.06%) and violet flower absolute.

The Uses of 2-Decanone

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 used as a solvent and an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is also used in perfumes.

The Uses of 2-Decanone

brushed block copolymers via conjugation through an acid-labile hydrazone linker to poly(ethylene glycol)-poly(aspartate hydrazide) block copolymers
methyl ketones

Definition

ChEBI: A methyl ketone that is decane in which the methylene hydrogens at position 2 are replaced by an oxo group.

Production Methods

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.

Aroma threshold values

Medium-type strength odor, orange floral.

General Description

2-Decanone is a constituent of the essential oil of Ruta chalepensis L., which is used in the production of food, drugs and perfumery.

Safety Profile

Slightly toxic by ingestion. Aflammable liquid. When heated to decomposition it emitsacrid smoke and irritating vapors.
