依据前期研究全氟聚醚润滑油抗氧抗腐添加剂的结构特征，选择并合成了３个Ｎ－取代聚全氟甲乙醚苯酰胺抗氧抗腐添加剂．经光谱分析发现，合成的３个产物中苯环的紫外特征吸收峰分别在２４０．７，２１５．４和 ２３０．１ｎｍ附近；Ｃ＝Ｏ的红外特征吸收峰分别在１７１３．９，１７１２．２和１７１０．８ ｃｍ－１附近．测试合成的３个添加剂抗氧抗腐性能发现：加入合成的添加剂后，能将氟醚润滑油失重较空白样分别减少１／７，１／９，１／２５倍，可将Ａｌ２Ｏ３催化下的热分解温度提高１９～２２℃．理论和实验研究表明：含氮杂原子的聚全氟甲乙醚苯酰胺化合物，既能接受ＲｆＯ的电子，生成稳定的加合物，阻止ＲｆＯ反应；又能给出电子与金属发生化学吸附，形成保护膜，具有较好的抗氧抗腐蚀性能；在这类化合物的Ｎ原子上引入供电子基团或苯基，可增加添加剂的抗氧抗腐蚀性能．研究结果可为设计新的抗氧抗腐添加剂提供有用的信息．
According to the previous study of perfluoropolyether lubricating oil anti-corrosion additives structural characteristics, selected and synthesized three N-substituted poly-p-fluoroanisole anti-corrosion additives. The results of spectral analysis showed that the UV absorption peaks of the benzene rings in the three products were around 240.7, 215.4 and 230.1 nm, respectively. The infrared absorption peaks of C = O were 1713.9 and 1712.2 And around 1710.8 cm-1. The results showed that the weight loss of fluoroether lubricants decreased by 1/7, 1/9 and 1/25 times than that of blank samples respectively after addition of synthetic additives. The catalytic activity of Al2O3 Thermal decomposition temperature increased by 19 ~ 22 ℃. Theoretical and experimental studies have shown that poly (fluoroalkyl ether) benzamide compounds containing nitrogen atoms can not only accept the electrons of RfO and form stable adducts, but also prevent the RfO reaction. At the same time, The protective film has good anti-oxidation and anti-corrosion properties. The introduction of electron donating groups or phenyl groups on the N atoms of these compounds can increase the anti-oxidation and anti-corrosion properties of the additives. The results provide useful information for the design of new antioxidant and anti-corrosion additives.
