| Hazard Information | Back Directory | [Chemical Properties]
ARACHIDIC ACID is also known as eicosanoic acid, formula CH3(CH2)18COOH. A widely distributed, but minor, component of the fats of certain edible vegetable oils. Shining, white crystalline leaflets; soluble in ether, slightly soluble in water. Decomposes at 328 C. Commercial product derived from groundnut (peanut) oil. Used in organic synthesis, lubricating greases, waxes, and plastics. Source of arachidyl alcohol. | [Chemical Properties]
white glistening powder or flakes | [Occurrence]
Arachidic acid is a saturated long-chain fatty acid and a minor constituent of peanut oil, coconut oil and corn oil. | [Uses]
Arachidic acid is a saturated fatty acid and a minor constituent of peanut oil, coconut oil and corn oil. Arachidic acid is used for the production of detergents, photographic materials and lubricants
. | [Definition]
ChEBI: A C20 striaght-chain saturated fatty acid which forms a minor constituent of peanut (L. arachis) and corn oils. Used as an organic thin film in the production of liquid crystals for a wide variety of technical applications | [Preparation]
Eicosanoic acid is produced by catalytic hydrogenation of arachidonic acid. Arachidonic acid is obtained from food or by desaturation and chain elongation of the plant-rich essential fatty acid, linoleic acid. | [Reactions]
It has the properties of fatty acids, can react with NaHCO3 to form salts, and with alcohols to form esters and so on. | [Flammability and Explosibility]
Nonflammable | [Biochem/physiol Actions]
Arachidic acid is a saturated fatty acid with a 20 carbon chain. Arachidic acid occurs naturally in fish and vegetable oils. Diets rich in saturated fats like arachidic acid are associated with increased levels of serum low density lipoproteins. | [Purification Methods]
Crystallise the C20 acid pKEst ~ from absolute EtOH. [Beilstein 2 IV 1276.] |
