Embodiment 1
[0032] 1. Preparation of N-oleoylserine: Weigh 2.82g (0.01mol) of oleic acid and PCl 3 2.06g was placed in a dry three-neck flask equipped with a reflux condenser, heated to reflux for 4h, and the excess PCl was evaporated 3 , Distilled under reduced pressure to obtain oleoyl chloride. React oleoyl chloride with 1.05g of serine in an alkaline solution of pH 8-10 at 15-20°C for 4-5 hours. After the reaction, let it stand for cooling, acidify the reaction liquid with hydrochloric acid to pH 1-2, wash the oil layer with water and petroleum ether, and dry it to obtain N-oleoylserine.
[0033] 2.C 60Preparation of N-oleoylserine derivatives: Weigh 720mgC 60 Add it into 150ml of xylene, ultrasonically disperse for 1.5h, add 2g of N-oleoylserine, fill with nitrogen, react at 120°C for 8h, filter and wash four times with absolute ethanol, and dry under vacuum at 60°C to obtain C 60 N-oleoylserine derivatives.
[0034] 3. Preparation of environment-friendly high anti-wear lubricat...
Embodiment 2
[0036] Steps 1 and 2 are the same as above. Take 10g of sulfurized castor oil, 75g of trimethylolpropane ester, and a viscosity of 2mm at 100°C 2 / sPA0 11g in a three-necked flask, stirred and heated to 65°C for 1h, added 0.5g of methylene bisphenol antioxidant, 1.0g of low-basic calcium sulfonate rust inhibitor with a base value of 60mg KOH / g, continued to stir for 2h, and then Add the C prepared above 60 N-oleoylserine derivative 2.5g, ultrasonic dispersion 2h, the product is obtained.
