摘要
将苯并三氮唑与氯代乙酰苯胺衍生物进行反应,合成了3种苯并三氮唑乙酰苯胺衍生物,采用~1H NMR、^(13)C NMR、FT-IR、UV-vis、MS、元素分析和热失重分析(TGA)对其进行表征,确证了其结构。以这3种苯并三氮唑乙酰苯胺衍生物作为新型无灰无磷润滑油添加剂,利用四球摩擦磨损试验机考察了其在液体石蜡中的极压性能和抗磨性能,并初步探讨了摩擦过程的机理。结果表明,这3种化合物均能溶于大部分有机溶剂而难溶于水.在液体石蜡中溶解性能良好;它们的初始分解温度均高于245℃,能适应一般工况条件的要求;这类化合物在液体石蜡中都有良好承载能力,其中苯并三氮唑基-N-对氯乙酰苯胺(2a)的P_B值最大,可达900 N,与ZDDP相当;都能有效地减少钢球的磨斑直径,效果最好的是苯并三氮唑基-N-对甲氧基乙酰苯胺(2b)。
Three benzotriazole acetanilide derivative were synthesized by the reaction of benzotriazole with chloro-acetanilide, whose structures were determined by ^1H NMR, ^13C NMR, FT-IR, UV-vis, MS, elemental analysis and TGA. They were used as ash less and non-phosphorus novel lubricating oil additives. The tribological properties of these three benzotriazole acetanilide derivatives used as ash less and non phosphorus novel lubricating oil additives in liquid paraffin were evaluated by using a four-ball tester. A simple study on their tribological mechanism was carried out. The results showed that the three derivatives dissolved in many organic solvents （ethanol, acetone, benzene, acetate, rapeseed oil, et al）, especially, in liquid paraffin, and was insoluble in water. They start to thermally decompose above 245℃, indicating that they may be used as lubricating oil additives in conventional lubricating oils to meet the operation requirements. The three additives all have excellent load-carrying capacity, and the PB value of derivative 2a can reach 900N, higher than that of ZDDP. All of them possessed good anti-wear performance, especially the derivative 2b.
