n-뷰탈알데히드 C화학적 특성, 용도, 생산

화학적 성질

colourless liquid with a very unpleasant smell

화학적 성질

Butyraldehyde is a highly flammable, colorless liquid with a pungent odor.

화학적 성질

Butyraldehyde has a characteristic pungent odor.

출처

Reported found in the essential oils from flowers, fruits, leaves or bark of Monarda fistulosa L., Litsea cubeba, Bulgarian clary sage, cajeput, Eucalyptus cinerea, E. globules, and others, as well as in apple and strawberry aromas. Also reported found in fresh apple, pears, carrots, peas, soybean, butter, milk, black tea, roast chicken, peanuts, loganberry, honey, white wine and hog plums (Spondias mombins L.).

용도

n-Butyraldehyde is used to make rubberaccelerators, synthetic resins, and plasticizers;and as a solvent.

용도

Chiefly in the manufacture of rubber accelerators, synthetic resins, solvents, plasticizers.

정의

ChEBI: A member of the class of butanals that consists of propane bearing a formyl substituent at the 1-position. The parent of the class of butanals.

제조 방법

By dry distillation of calcium butyrate and calcium formate.

Aroma threshold values

Detection: 19 to 37 ppb; recognition: 11 to 27 ppb

Taste threshold values

Taste characteristics at 5 ppm: musty, fusel, fermented, bready and yeasty with a malty nuance.

일반 설명

A clear liquid with a pungent odor. Flash point 20°F. Boiling point 75.7°F (Hawley's). Less dense than water and insoluble in water. Vapors heavier than air.

공기와 물의 반응

Highly flammable. Insoluble in water.

반응 프로필

A colorless liquid, Butyraldehyde can react with oxidizing materials. In contact with strong acids or bases Butyraldehyde will undergo an exothermic condensation reaction. The dry aldehyde may undergo some polymerization reaction. Reacts vigorously with chlorosulfonic acid, nitric acid, sulfuric acid (oleum). [Sax, 9th ed., 1996, p. 607].

위험도

Flammable, dangerous fire risk.

건강위험

n-Butyraldehyde is a mild skin and eye irritant.The liquid in 100% pure form producedmoderate irritation on guinea pig skin. Theirritation resulting from 20 mg in 24 hours on rabbit eye was moderate. A higher dosecould produce severe irritation.
Toxicity of n-butyraldehyde is very low.The effect is primarily narcotic. No toxiceffect, however, was observed in mice from 2-hour exposure at a concentration of 44.6 g/m3.At a higher concentration, 174 g/m3 for30 minutes, it exhibited a general anestheticeffect on rats. Subcutaneous administrationof a high dose, >3 g/kg, produced the sameeffect, affecting the kidney and bladder.

건강위험

Inhalation will cause irritation and possibly nausea, vomiting, headache, and loss of consciousness. Contact with eyes causes burns. Skin contact may be irritating.

화재위험

Behavior in Fire: Vapors are heavier than air and may travel considerable distance to a source of ignition and flash back. Fires are difficult to control due to ease of reignition.

화재위험

Flash Point (°F): 15 ℃, 20 ℃; Flammable Limits in Air (%): 2.5-10.6; Fire Extinguishing Agents: Dry chemical, carbon dioxide, foam; Fire Extinguishing Agents Not To Be Used: Not pertinent; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Vapors are heavier than air and may travel considerable distances to a source of ignition and flash back. Fires are difficult to control because of recognition; Ignition Temperature (deg. F): 446; Electrical Hazard: Not pertinent; Burning Rate: 4.4 mm/min.

화학 반응

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: May occur in the presence of heat, acids or alkalis; Inhibitor of Polymerization: Not pertinent.

Safety Profile

Moderately toxic by ingestion, inhalation, skin contact, intraperitoneal, and subcutaneous routes. Severe skin and eye irritant. Human immunologcal effects by inhalation: delayed hypersensitivity. See also ALDEHYDES. Highly flammable liquid. To fight fire, use foam, CO2, dry chemical. Incompatible with oxidzing materials. Reacts vigorously with chlorosulfonic acid, HNO3, oleum, H2SO4. When heated to decomposition it emits acrid smoke and fumes

응급 처치

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As

운송 방법

UN1129 Butyraldehyde, Hazard Class: 3; Labels: 3—Flammable liquid

비 호환성

May form explosive mixture with air. Butyraldehyde can presumably form explosive peroxides, and may polymerize due to heat or contact with acids or alkalis. 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, caustics, ammonia, aliphatic amines; alkanolamines, aromatic amines. May accumulate static electrical charges, and may cause ignition of its vapors. Possible self-reaction in air; undergoes rapid oxidation to

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.
