Uses
1-Heptanol have also been used in the fragrance industry due to its pleasant smell.
Definition
ChEBI: 1-heptanol is an alkyl alcohol that is heptane in which a hydrogen of one of the methyl groups is substituted by a hydroxy group. It has been isolated from Capillipedium parviflorum. It has a role as a plant metabolite, a fragrance and a flavouring agent. It is a primary alcohol, an alkyl alcohol and a volatile organic compound. It derives from a hydride of a heptane.
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.
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.
Health Hazard
Low toxicity; liquid may irritate eyes.
Flammability and Explosibility
Non flammable
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. [Beilstein 1 IV 1731.]
