3-Heptanone Chemical Properties,Usage,Production

  • Description 3-Heptanone has a powerful, green, fatty, fruity odor and a melon, banana flavor. Prepared from n-hept-2-one by hydration.
  • Chemical Properties 3-Heptanone has a fruity, green, fatty, sweet, ethereal, powerful odor and a melon, banana favor.
  • Chemical Properties colourless liquid
  • Chemical Properties Ethyl butyl ketone is a colorless liquid with a powerful, fruity odor.
  • Occurrence 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
  • Uses Ethyl butyl ketone is used as a solvent fornitrocellulose and polyvinyl resins, and as anintermediate in organic synthesis.
  • Uses Solvent mix for air-dried and baked finishes, for polyvinyl and nitrocellulose resins.
  • Definition ChEBI: A dialkyl ketone with butyl and ethyl as the two alkyl groups.
  • Preparation From n-hept-2-one by hydration.
  • Production Methods 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.
  • Aroma threshold values Detection: 7 5 to 160 ppb.
  • Taste threshold values Taste characteristics at 50 ppm: ketonic, with a cheese-like creamy character.
  • General Description Colorless odorless liquid with a mild fruity odor. Flash point 140°F.
  • Air & Water Reactions Flammable.
  • Reactivity Profile 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].
  • Hazard Moderate fire risk.
  • Health Hazard Short term exposure can cause irritation of eyes, nose, throat and lungs. High concentrations may cause headache, dizziness or unconsciousness.
  • Health Hazard Inhalation of the vapor of ethyl butyl ketonecan cause irritation to the eyes, skin, andmucous membranes. Its irritation effect wasmild on rabbit skin and eyes. Prolonged skincontact can cause dermatitis. Exposure to4000 ppm for 4 hours proved fatal to rats.Ingestion can cause headache and narcosis,and in large doses coma can occur.
    LD50 value, oral (rats): 2760 mg/kg.
  • Fire Hazard 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.
  • Potential Exposure 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
  • Environmental Fate Chemical/Physical. 3-Heptanone will not hydrolyze because it has no hydrolyzable functional group.
  • Shipping UN1224 Ketones, liquid, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required.
  • Incompatibilities May form explosive mixture with air. Violent reaction with strong oxidizers, acetaldehyde, perchloric acid. Attacks some plastics, rubber and coatings
  • 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
