Erucamide

Description

13-Docosenamide is the amide of docosenoic acid. It was first identified in the cerebrospinal fluid of sleep-deprived cats. It has also been detected in the cerebrospinal fluid of rats and humans. 13-Docosenamide causes reduced mobility and slightly lessened awareness in rats, whereas 9-octadecenamide induces physiological sleep.

Description

Erucamide is also known as 13-Docosenamide or Erucylamide. It is in the form of white flakes or beads. It is soluble in isopropanol, slightly soluble in alcohol and acetone.¹ In industry, cis-13-docosenoamide is used in the formulations of anti-adhesive agents, lubricants, and lubricant additives to reduce their friction coefficient and to make films easier to handle.² It is used as a standard to determine fatty acid amides in polyethylene packaging film by GC/MS.³

Chemical properties

Erucamide is a fatty acid amide derived from erucic acid, which is found in vegetable oil. It is a odorless waxy solid that can dissolve in isopropanol and has low solubility in alcohol and acetone. It is also combustible. Its molecular structure consists of a long unsaturated C22 chain and a polar amine group, which gives it strong surface polarity, a high melting point, and good thermal stability. Because of these properties, it finds extensive applications in industries such as plastics, rubber, printing, and machinery.

The Uses of Erucamide

Erucamide is primarily used as a polymer additive, with plastic additive 21 is a plasticizer; used in preparation of natural mineral modified degradable polymer flame-retardant composite material.

Preparation

Erucamide is prepared by reaction of erucic acid with anhydrous ammonia. The reaction of erucic acid with anhydrous ammonia is as follows: C22H42O2 + NH3 → C22H43NO2.

Definition

ChEBI: Erucamide is a primary fatty amide resulting from the formal condensation of the carboxy group of erucic acid with ammonia. It is commonly used as a slip additive in the plastic manufacturing industry. It has a role as a human metabolite, a rat metabolite, a mammalian metabolite, a plant metabolite and an EC 3.1.1.7 (acetylcholinesterase) inhibitor. It is functionally related to an erucic acid.

General Description

Erucamide is a migratory additive that is commonly placed in polyolefin films to reduce their coefficient of friction (COF), a good attribute for high speed packaging operations.
