Description

Heptanoic acid, also called enanthic acid, is an organic compound composed of a seven - carbon chain terminating in a carboxylic acid. It is an oily liquid with an unpleasant, rancid odor. It contributes to the odor of some rancid oils. It is slightly soluble in water, but very soluble in ethanol and ether.

Chemical Properties

Heptanoic acid has a disagreeable rancid odor. The spectroscopically pure acid exhibits a faint tallow-like odor. Heptanoic acid may be prepared by oxidation of heptaldehyde with potassium permanganate in diluted sulfuric acid.

Chemical Properties

Heptanoic acid has a disagreeable rancid, sour, sweat-like, fatty odor The spectroscopically pure acid exhibits a faint fallow-like odor.

Chemical Properties

colourless liquid with a pungent and rancid odour

Uses

Intermediates of Liquid Crystals

Definition

ChEBI: A C7, straight-chain fatty acid that contributes to the odour of some rancid oils. Used in the preparation of esters for the fragrance industry, and as an additive in cigarettes.

Preparation

By oxidation of heptaldehyde with potassium permanganate in diluted sulfuric acid.

Taste threshold values

Taste characteristics at 5 ppm: waxy, cheesy, fruity, dirty and fatty.

General Description

A colorless liquid with a pungent odor. Less dense than water and poorly soluble in water. Hence floats on water. Very corrosive. Contact may likely burn skin, eyes, and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Flash point near 200°F.

Air & Water Reactions

Slightly soluble in water.

Hazard

Combustible.

Health Hazard

Harmful if swallowed, inhaled, or absorbed through skin. Extremely destructive to mucous membranes, upper respiratory tract, skin, and eyes. Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting.

Fire Hazard

Heptanoic acid is probably combustible.
