출처
Reported found in apple juice, banana, peach, pear, spearmint oil, Parmesan cheese, butter, cream, lean fsh, fsh oil, roasted chicken, cooked beef, coffee, peanut oil, pecan, yellow passion fruit, plumcot, beans, plum brandy, sesame seed, mango and cooked shrimps
용도
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.
생산 방법
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.
제조 방법
From n-hept-2-one by hydration.
정의
ChEBI: A dialkyl ketone with butyl and ethyl as the two alkyl groups.
일반 설명
Colorless odorless liquid with a mild fruity odor. Flash point 140°F.
공기와 물의 반응
Flammable.
반응 프로필
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].
위험도
Moderate fire risk.
건강위험
Short term exposure can cause irritation of eyes, nose, throat and lungs. High concentrations may cause headache, dizziness or unconsciousness.
화재위험
Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as carbon dioxide and carbon monoxide, may be formed when involved in fire.
Safety Profile
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.
잠재적 노출
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
환경귀착
Chemical/Physical. 3-Heptanone will not hydrolyze because it has no hydrolyzable functional
group.
운송 방법
UN1224 Ketones, liquid, n.o.s., Hazard Class: 3;
Labels: 3-Flammable liquid, Technical Name Required.
비 호환성
May form explosive mixture with air.
Violent reaction with strong oxidizers, acetaldehyde, perchloric acid. Attacks some plastics, rubber and coatings
폐기물 처리
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
