Butyraldehyde Chemical Properties,Usage,Production

  • Description 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.

  • Description Butyraldehyde (butanal, IUPAC) is a water-white liquid with a pungent aldehyde odor. Butyraldehyde is a dangerous fire risk, with a flammable range of 2.5%–12.5% in air. Boiling point is 168°F (75°C), flash point is 10°F (?12°C), and ignition temperature is 446°F (230°C). It is slightly soluble in water, with a specific gravity of 0.8, which is lighter than water. Vapor density is 0.804, which is lighter than air. In addition to flammability, butyraldehyde is corrosive and causes severe eye and skin burns. It may be harmful if inhaled. The four-digit UN identification number is 1129. The NFPA 704 designation is health 3, flammability 3, and reactivity 2. The primary uses of butyraldehyde are in plastics and rubber and as a solvent.
  • Chemical Properties colourless liquid with a very unpleasant smell
  • Chemical Properties Butyraldehyde is a highly flammable, colorless liquid with a pungent odor.
  • Chemical Properties Butyraldehyde has a characteristic pungent odor.
  • Occurrence 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.).
  • Uses n-Butyraldehyde is used to make rubberaccelerators, synthetic resins, and plasticizers;and as a solvent.
  • Uses Butanal is used in the manufacture of rubber accelerators, synthetic resins, solvents, and plasticizers. n-Butyraldehyde is used as an intermediate in the manufacturing of plasticizers, alcohols, solvents, and polymers (such as 2-ethylhexanol, n-butanol, trimethylolpropane, n-butyric acid, polyvinyl butyral, and methyl amyl ketone). It is also used as an intermediate to make pharmaceuticals, agrochemicals, antioxidants, rubber accelerators, textile auxiliaries, perfumery, and flavors. It has no therapeutic use at the present time.
  • Uses Chiefly in the manufacture of rubber accelerators, synthetic resins, solvents, plasticizers.
  • Definition 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.
  • Preparation 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.
  • 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].
  • Hazard 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.
  • 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
  • Carcinogenicity Although butyraldehyde interacts with DNA, no experimental studies of its carcinogenic potency were found.
  • Environmental Fate Butanal does not possess high acute toxicity but is a potent irritant of the skin, eyes, and upper respiratory tract. The mechanism of toxicity probably involves direct reaction between the active aldehyde group and cellular components.
  • Shipping UN1129 Butyraldehyde, Hazard Class: 3; Labels: 3—Flammable liquid
  • Toxicity evaluation The primary degradation process in soil is expected to be biodegradation. A number of biological screening studies have demonstrated that butyraldehyde is readily biodegradable.
    The major environmental fate processes for butyraldehyde in water are biodegradation and volatilization. A number of biological screening studies have demonstrated that butyraldehyde is readily biodegradable. Volatilization half-lives of 9 h and 4.1 days have been estimated for a model river (1-m deep) and a model pond, respectively. Aquatic hydrolysis, adsorption to sediment, and bioconcentration are not expected to be important fate processes.
  • Incompatibilities 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.
