使用
3-Heptanone is a seven carbon ketone with a "fruity" scent. It is often used as a perfume/fragrance industry and can also be applied as a solvent.
調製方法
EnBK is produced either by catalytic dehydrogenation of
3-heptanol or by hydrogenation of the mixed alcohol condensation
product of propionaldehyde and methyl ethyl
ketone. Commercial samples can be 95% pure.
製造方法
From n-hept-2-one by hydration.
定義
ChEBI: A dialkyl ketone with butyl and ethyl as the two alkyl groups.
一般的な説明
Colorless odorless liquid with a mild fruity odor. Flash point 140°F.
空気と水の反応
Flammable.
反応プロフィール
3-Heptanone is 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. Reacts with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. May react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. Irritating vapors and toxic gases may be formed when involved in fire [USCG, 1999].
危険性
Moderate fire risk.
健康ハザード
Short term exposure can cause irritation of eyes, nose, throat and lungs. High concentrations may cause headache, dizziness or unconsciousness.
火災危険
Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.
安全性プロファイル
Moderately toxic by
ingestion and inhalation. A skin and eye
irritant. A flammable liquid. Can react with
oxidizing materials. To fight fire, use foam,
Co2, dry chemical. See also KETONES.
職業(yè)ばく露
Ethyl butyl ketone is used as a solvent
and as an intermediate in organic synthesis. It is a solvent
for vinyl and nitrocellulose resins. It is used in food
flavoring
環(huán)境運命予測
Chemical/Physical. 3-Heptanone will not hydrolyze because it has no hydrolyzable functional
group.
Solubility in organics
Insoluble in water, soluble in alcohol, miscible with oils.
輸送方法
UN1224 Ketones, liquid, n.o.s., Hazard Class: 3;
Labels: 3-Flammable liquid, Technical Name Required.
不和合性
May form explosive mixture with air.
Violent reaction with strong oxidizers, acetaldehyde, perchloric acid. Attacks some plastics, rubber and coatings
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
