2-Heptanol Usage And Synthesis
  • Description2-heptanol is one isomer of heptanol. It can be used as a flavoring agent and used in perfumery. It is a common agent in analytic chemistry. It can also be used as the intermediate of plasticizer, pharmacy, fragrance and wetting agent and as the co-solvent to be supplemented to nitro-lacquer solvent.

  • Description2-Heptanol has a brassy, herbaceous odor reminiscent of lemon and a fruity, green, somewhat bitter taste. 2-Heptanol may be synthesized from amyl magnesium bromide and acetaldehyde; by reduction of amyl methyl ketone with sodium metal in alcohol; by the action of Penicillium palitans on peanut oil.

  • Chemical Propertiescolourless liquid
  • OccurrenceReported found in apple, banana, berries, grapes, strawberry jam, coconut, coconut milk, cooked potato, clove bud, ginger, cheeses, fried beef, chicken fat, cognac, beer, hop oil, brandy, rum, grape wines, cocoa, coffee, tea, flberts, honey, soy- beans, Arctic bramble, passion fruit and juices, beans, mushrooms, calamus, buckwheat, sweet corn, malt, curcuma, mastic gum leaf oil and other sources
  • UsesSolvent for synthetic resins, frothing agent in ore flotation.
  • PreparationFrom amyl magnesium bromide and acetaldehyde; by reduction of amyl methyl ketone with sodium metal alcohol; by the action of Penicillium palitans on peanut oil.
  • Aroma threshold valuesDetection: 41 ppb to 81 ppb.
  • General DescriptionA clear colorless alcohol with a mild alcohol odor. Density approximately 6.8 lb / gal and insoluble in water. Hence floats on water. Flash point 130°F. Soluble in most organic liquids. Boiling point 320.7°F. Moderately toxic. Used as a solvent for various resins and as a flotation agent for ore processing.
  • Air & Water ReactionsFlammable. Insoluble in water.
  • Reactivity ProfileMETHYLAMYL CARBINOL is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
  • HazardModerate fire risk.
  • Health HazardInhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
