| Molecular Formula | C38H71N3O4 |
| Physical and Chemical Properties | The chemical quality product is reddish brown semi-solid. |
| Use | Use of this product is oil-soluble ashless rust inhibitor, good acid neutralization, salt water and salt fog resistance is poor, the black metal has good moisture resistance. It also has a certain protective effect on aluminum, copper and its alloys. Compound with other rust inhibitors to prepare anti-rust sealed grease, inter-process anti-rust oil. Combined with detergent and dispersant, anti-rust lubricating oil for internal combustion engine and aero-engine is prepared. In addition, it can also be used as a co-solvent of benzotriazole and a preparation of anti-rust compound. The dosage is 00.015% in No. 8 liquid transmission oil, and 1.5% in instrument sealing anti-rust oil and turbine jet oil. |
Put equimolar oleic acid and diethylenetriamine into the reaction kettle and heat and melt. Oleamide is dehydrated at about 150 ℃, and then heated to 240~250 ℃ for further dehydration closed loop to form 2-heptadecenyl-N-aminoethylimidazoline. Then it is cooled and moved into a salt kettle, neutralized with succinic acid at about 100 ℃ to form salt, and the acid value reaches 30~80 mgKOH/g as the end point, and the finished product is packaged while hot.
