Erucamide

Описание

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

Химические свойства

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.

Использование

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.

Подготовка

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.

Общее описание

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.

Биологическая активность

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.
