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.

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
colourless liquid

ore flotation.
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.
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.
Definition
ChEBI: 2-heptanol is an aliphatic alcohol.
Aroma threshold values
Detection: 41 ppb to 81 ppb.
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.
