| | 2-Heptanol Usage And Synthesis |
| Description | 2-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. | | References | [1] Giersch, Wolfgang. "Use of 2,5,6,-trimethyl-2-heptanol as a perfuming and a flavoring agent." (2004).

| | Description | 2-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 Properties | 2-Heptanol has a brassy, herbaceous odor reminiscent of lemon and a fruity, green, somewhat bitter taste. | | Chemical Properties | colourless liquid | | Occurrence | Reported 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 | | Uses | 2-Heptanol may be used as an analytical standard for the determination of the analyte in volatile compound mixtures, fruit samples and aqueous samples by various chromatography techniques. | | Uses | Solvent for synthetic resins, frothing agent in
ore flotation. | | Definition | ChEBI: 2-heptanol is an aliphatic alcohol. | | Preparation | From 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 values | Detection: 41 ppb to 81 ppb. | | Synthesis Reference(s) | Journal of the American Chemical Society, 89, p. 1522, 1967 DOI: 10.1021/ja00982a043
The Journal of Organic Chemistry, 43, p. 4255, 1978 DOI: 10.1021/jo00415a065 | | General Description | A 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 Reactions | Flammable. Insoluble in water. | | Reactivity Profile | METHYLAMYL 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. | | Hazard | Moderate fire risk. | | Health Hazard | Inhalation 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. |
