Hexanoic acid Usage And Synthesis


Description

Hexanoic acid (also known as Caproci acid, general formula: C5H11COOH) belongs to a kind of saturated medium-chain fatty acid derived from hexane with an unpleasant odor. It is a colorless oily liquid naturally existing in various plant and animal fats and oils. One of its major applications is for the manufacturing of its esters for being artificial flavors. It is also important for the manufacturing of hexyl derivatives such as hexylphenols. Hexanoic acid belongs to medium chain triglycerides (MCT) that are widely used as a nutrition supplement that added to foods, drugs and cosmetics.

Chemical Properties

Hexanoic acid has an unpleasant odor reminiscent of copra oil and it exhibits an acrid taste. Hexanoic acid may be prepared by fractionation of the volatile fatty acids of coconut oil.

Chemical Properties

Hexanoic acid has a sickening, sweaty, rancid, sour, sharp, pungent, cheesy, fatty, unpleasant odor reminiscent of copra oil. It exhibits an acrid taste

Chemical Properties

colourless liquid

Uses

Intermediates of Liquid Crystals

Uses

manufacture of esters for artificial flavors, and of hexyl derivatives, especially hexylphenols, hexylresorcinol, etc.

Definition

ChEBI: A C6, straight-chain saturated fatty acid.

Preparation

By fractionation of the volatile fatty acids of coconut oil

Definition

An oily carboxylic acid found (as glycerides) in cow’s milk and some vegetable oils.

Aroma threshold values

Detection: 93 ppb to 10 ppm

General Description

A white crystalline solid or colorless to light yellow solution with an unpleasant odor. Insoluble to slightly soluble in water and less dense than water. Contact may severely irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used to make perfumes.

Air & Water Reactions

Slightly water soluble.

Hazard

Strong irritant to tissue.

Health Hazard

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

Fire Hazard

Special Hazards of Combustion Products: Irritating vapor may be generated.

Purification Methods

Dry the acid with MgSO4 and fractionally distil it from CaSO4. [Beilstein 2 IV 917.]
