Butyraldehyde Chemical Properties,Uses,Production


Butanal (N-butyraldehyde) is an organic compound which is the aldehyde derivative of butane. It appeases as a clear liquid. Butyraldehye is used mainly as an intermediate in the production of synthetic resins, rubber vulcanization accelerators, solvents, and plasticizers. It is also an intermediate for the manufacture of pharmaceuticals, crop protection products, pesticides, antioxidants, tanning auxiliaries, and perfumes. Butyraldehyde has a characteristic pungent odor and it is used as a food additive.

Chemical Properties

colourless liquid with a very unpleasant smell

Chemical Properties

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


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


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


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.

General Description

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.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

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].


Flammable, dangerous fire risk.

Health Hazard

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.

Health Hazard

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

Fire Hazard

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.

Fire Hazard

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.

Chemical Reactivity

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

First aid

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


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


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

Waste Disposal

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.
