What are the properties and uses of erucic acid? Introduction to erucic acid

[Alias]cis-13-docosenoic acid, rapeseed acid.

［Molecular Formula］C22H42O2

[Properties of Erucic Acid]Colorless or white needle-like crystals. The phase density is 0.860 (55℃), the melting point is 33.5℃, the boiling point is 265℃ (2.0kPa), and it begins to decompose when heated to 381.5℃. The refractive index is 1.4534 (45℃), the octaiodine value is 74.98, and the saponification value is 165.72. Insoluble in water, easily soluble in ether, soluble in ethanol and methanol. Its unsaturated double bond can undergo hydrogenation reaction, and behenic acid is generated after hydrogenation. Glycerides of erucic acid are the main component of mustard oil and are also found in other vegetable oils.

[Use of Erucic Acid] It is an intermediate in the manufacture of fine chemical products and can be used to manufacture surfactants, emulsifiers, and lubricants. , plasticizers, drug absorbers, preservatives, detergents, brighteners and softeners, etc. After cleavage of erucic acid, pelargonic acid and dodecanedioic acid can be produced. The latter can be used to make artificial musk, nylon 13, and nylon 1313.

[Brief preparation method] Using rapeseed oil as raw material, mixed fatty acids are first prepared. According to different boiling points, the mixed fatty acids are heated and fractionated. Erucic acid is isolated.

[Safety and Protection]This product is non-toxic. Packed in plastic barrel, net weight 40kg. Store and transport according to general chemical regulations. Store in a cool, dry place.
