| 1-Heptanol Usage And Synthesis |
| Description | Heptyl alcohol has a faint, aromatic, fatty odor and a pungent,
spicy taste. It may be synthesized by reduction of enanthic aldehyde, which is a distillation product of castor oil. | | Chemical Properties | Heptyl alcohol has a fragrant, woody, heavy, oily, faint, aromatic, fatty odor and a pungent, spicy taste. | | Chemical Properties | colourless liquid | | Occurrence | Reported found in a few essential oils, hyacinth, violet leaves, Litsea zeylanica Also reported found in apple, banana, citrus peel oils, orange juice, bilberry, cranberry, blueberry, other berries, currants, melon, papaya, peach, pear, pineapple, asparagus, peas, potato, mustard, cheeses, butter, milk, meats, hop oil, beer, cognac, rum, bourbon whiskey, grape wines, cocoa, tea, flberts, pecans, peanuts, soybeans, passion fruit juice, olive, macadamia nuts, mango, tamarind, fgs, cardamom, rice, calamus, dill, corn, malt, kiwifruit, truffe, nectarine, crab, crayfsh, clams and other sources | | Uses | 1-Heptanol, is used in the fragrance industry due to its pleasant smell. | | Uses | 1-Heptanol have also been used in the fragrance industry due to its pleasant smell. | | Preparation | By reduction of enanthic aldehyde, which is a distillation product of castor oil. | | Production Methods | 1-Heptanol is produced by reacting hexenes with carbon
monoxide in the oxo process or by the catalytic reduction
of heptaldehyde. It has little commercial value except in
fragrances and as an artificial flavoring agent. | | Aroma threshold values | Detection: 3 ppb. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 57, p. 1061, 1992 DOI: 10.1021/jo00030a003Synthesis, p. 701, 1979 DOI: 10.1055/s-1979-28800 | | General Description | Watery colorless liquid with a weak alcohol odor. Floats on water. | | Reactivity Profile | Heptan-1-ol 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 | Combustible. | | Health Hazard | Low toxicity; liquid may irritate eyes. | | Flammability and Explosibility | Nonflammable | | 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: Not pertinent; Inhibitor of Polymerization: Not pertinent. | | Biochem/physiol Actions | Taste at 1-10 ppm | | Purification Methods | Shake the alcohol with successive lots of alkaline KMnO4 until the colour persists for 15minutes, then dry it with K2CO3 or CaO, and fractionally distil it.
