説明
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.
化学的特性
colourless liquid
天然物の起源
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
使用
1-Heptanol have also been used in the fragrance industry due to its pleasant smell.
製造方法
By reduction of enanthic aldehyde, which is a distillation product of castor oil.
調製方法
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.
一般的な説明
Watery colorless liquid with a weak alcohol odor. Floats on water.
反応プロフィール
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.
危険性
Combustible.
健康ハザード
Low toxicity; liquid may irritate eyes.
化学反応性
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.
純化方法
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. [Beilstein 1 IV 1731.]
