It is understood that: Erucamide is an important derivative of erucic acid. It is an excellent fine chemical product with a wide range of applications. It is in the form of white granules or powder. Soluble in organic solvents such as ethanol and ether. The production method is obtained by ammoniation and dehydration of erucic acid and ammonia under the action of a catalyst. Erucamide, as an important derivative of erucic acid, is an excellent fine chemical product with a wide range of applications. Because it has a high melting point and good thermal stability (stable at 273°C), it is mainly used as an anti-sticking agent and slip agent for various plastics and resins, and an excellent lubricant and antistatic agent for extruded films. .

Oleic acid amide is an unsaturated fatty acid amide, which is white crystal or granular solid with polymorphic structure and odorless. It is easily hydrolyzed in the presence of acid, alkali solution or enzyme catalyst. After hydrolysis Oleic acid and ammonia are also generated. It can reduce the friction between the internal friction film and the conveying equipment during the processing of resin, etc., simplify the operation of the final product, thereby increasing the production volume. For example, it can be used as a lubricant in polyethylene processing to reduce the melt viscosity of resin particles and improve fluidity. Industrially, it is produced through the acylation reaction of oleic acid and anhydrous ammonia in the presence of a catalyst.

Specific differences in functions and uses: The main uses of erucamide are smoothness, anti-adhesion, and brightness; oleic acid amide is opening, lubrication, and anti-adhesion. The uses of the two are similar but not the same. If the opening is made of general plastic material, such as PVC/PE, oleic acid amide is the best, high quality and low price. However, if it is used in some high-end plastics, such as PP/TPU/BOPP, erucamide is used as the opening. The properties and melting point of erucamide are better than those of oleic acid amide, and the stable processing performance of erucic acid amide is better than that of oleic acid amide. Good, no yellowing or aging. In addition, erucic acid amide precipitates slowly, so the long-term friction coefficient of erucic acid amide is lower than that of oleic acid amide.
