Подготовка
By reduction of enanthic aldehyde, which is a distillation product of castor oil.
Методы производства
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.

Профиль реактивности
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.
Опасность
Combustible.
Угроза здоровью
Low toxicity; liquid may irritate eyes.
Химическая реактивность
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.
Методы очистки
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.]
