化学的特性
CLEAR COLOURLESS LIQUID
使用
3-Methyl-2-butanone is used for synthesis of heterocyclic compounds and important intermediate of medicine. It is used as an industrial solvent.
一般的な説明
A colorless liquid with a pleasant odor. Flash point below 70°F. Less dense than water. May be toxic by inhalation and skin absorption. Used as a solvent.
空気と水の反応
Highly flammable. Soluble in water.
反応プロフィール
Ketones, such as 3-Methyl-2-butanone, 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.
危険性
Toxic material. Embryo/fetal damage andneonatal toxicity.
健康ハザード
Irritating to the eyes, nose, throat, upper respiratory tract, and skin.
火災危険
Special Hazards of Combustion Products: Acrid smoke and fumes
安全性プロファイル
Poison by ingestion.
Mildly toxic by inhalation and skin contact.
Mutation data reported. A skin and eye
irritant. Flammable when exposed to heat or
flame; can react vigorously with oxidizing
materials. When heated to decomposition it
emits acrid smoke and irritating fumes.
職業ばく露
This ketone is used as a solvent for
nitrocellulose lacquers.
輸送方法
UN23973-Methylbutan-2-one, Hazard Class: 3;
Labels: 3-Flammable liquid.
純化方法
Reflux the ketone with a little KMnO4. Fractionate it through a spinning-band column, dry with CaSO4 and distil it. [Beilstein 1 IV 3287.]
不和合性
Vapors may form explosive mixture with
air. Ketones are incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides, nitrated amines, azo,
diazo, azido compounds, carbamates, organic cyanates
廃棄物の処理
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All
federal, state, and local environmental regulations must
be observed.
