説明
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.

使用
2-Nonanone is used as a component of several food sources and can be used as a flavoring agent.
製造方法
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
定義
ChEBI: A methyl ketone that is nonane in which the methylene hydrogens at position 2 are replaced by an oxo group.
一般的な説明
Colorless liquid.
空気と水の反応
Highly flammable. Water insoluble.
反応プロフィール
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.
健康ハザード
May be harmful by inhalation, ingestion, or skin absorption. May cause eye and skin irritation.
安全性プロファイル
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.
