• 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.

• 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.

• Allgemeine Beschreibung

  Colorless liquid.

• Air & Water Reaktionen

  Highly flammable. Water insoluble.

• Reaktivität 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.

• Flammability and Explosibility

  Non flammable

• 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.
