Beschreibung
2-Nonanone has a characteristic rue odor and a rose and teα-like flavor. May be prepared by dry distillation of barium caprylate and barium acetate at 0.5 - 2 mmHg; or by oxidation of methyl heptyl carbinol at room temperature using chromic acid; it can be isolated also from natural products by fractional distillation.
Chemische Eigenschaften
2-Nonanone has a characteristic rue odor. It has a rose and tea-like flavor.
Occurrence
Reported found in the essential oil of rue (Ruta angustifolia Pers., R. bracteosa, R. Montana L. and R. gravelolens); also identified in the oil of carnation, in coconut oil and in the distillate from leaves of a variety of Boronia ledifolia; reported
found in mixture with methyl nonyl ketone in the essential oil of Ruta chalepensis. Also reported found in banana, lemon peel oil,

Verwenden
2-Nonanone is used as a component of several food sources and can be used as a flavoring agent.
It finds some use in perfume com-
positions as a powerful ingredient in Lavender
compositions, in Citrus cologne types and in
variations of New Mown Hay, etc.
synthetische
By dry distillation of barium caprylate and barium acetate at 0.5 to 2 mmHg; by oxidation of methylheptyl carbinol at
room temperature using chromic acid; it can be isolated also from natural products by fractional distillation
Definition
ChEBI: A methyl ketone that is nonane in which the methylene hydrogens at position 2 are replaced by an oxo group.
Allgemeine Beschreibung
Colorless liquid.
Air & Water Reaktionen
Highly flammable. Water insoluble.
Reaktivit?t anzeigen
Ketones, such as 2-Nonanone, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.
Health Hazard
May be harmful by inhalation, ingestion, or skin absorption. May cause eye and skin irritation.
Sicherheitsprofil
Moderately toxic by ingestion.Combustible when exposed to heat or flame; can reactwith oxidizing materials. To fight fire, use foam, CO2, drychemical. When heated to decomposition it emits acridsmoke and irritating fumes.
