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

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

[Molecular formula]C22H42O2

[Properties of erucic acid]Colorless or white needle-like crystals. The phase-time density is 0.860 (55°C), the melting point is 33.5°C, the boiling point is 265°C (2.0kPa), and it begins to decompose when heated to 381.5°C. The refractive index is 1.4534 (45°C), the iodine 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 can be generated after hydrogenation. Glycerides of erucic acid are the main constituents of mustard oil and are also present in other vegetable oils.

[Use of erucic acid]It is an intermediate in the manufacture of fine chemical products, and can be used to make surfactants, emulsifiers, lubricants , plasticizers, drug absorbers, preservatives, detergents, brighteners and softeners, etc. After cracking erucic acid, nonanoic acid and dodecanedibasic acid can be produced, which can be used to make artificial musk, nylon 13, and nylon 1313.

［Brief method］Using rapeseed oil as raw material, firstly prepare mixed fatty acids, according to different boiling points, heat and fractionate from mixed fatty acids Erucic acid was isolated.

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