摘要:
为了发现新型环境友好型润滑油添加剂,以格氏法、羧基化、酰肼化和亲核取代反应首次制备了11种N′,N′-双取代酰肼化合物。并采用FTIR、1HNMR和MS对其结构进行了表征。并将其作为偏苯三酸酯的润滑油添加剂,利用微摩擦试验机分别测试其质量分数1%的添加量时98 N载荷下的摩擦学性能,结果表明:N′,N′-双取代酰肼化合物具有显著的减摩抗磨作用,添加N′,N′-二丁基戊酰肼、N′,N′-二(2-乙基己基)戊酰肼、4-甲基-N′,N′-二对甲基苯甲酰肼、4-甲基-N′,N′-二乙基苯甲酰肼的偏苯三酸酯的摩擦系数均低于无添加的偏苯三酸酯,添加N′,N′-二乙基戊酰肼的偏苯三酸酯的摩擦系数下降趋势最大,达最小值0.051 2;在偏苯三酸酯中添加11种酰肼类化合物的偏苯三酸酯的钢球体积磨损量均低于无添加的偏苯三酸酯,其中添加N′,N′-二(2-乙基己基)苯甲酰肼的偏苯三酸酯的钢球体积磨损量最小;比无添加的偏苯三酸酯减少了87.13 %,有望成为绿色高效的减摩抗磨润滑油添加剂。
Abstract:
To find new environment-friendly lubricant additives, eleven N′,N′-disubstituted hydrazide compounds were firstly prepared via format method, carboxylation, hydrazide reaction, and nucleophilic substitution reaction. Their structures were characterized by Fourier-transform infrared spectrometry, proton nuclear magnetic resonance spectrometry and mass spectroscopy. Their tribological properties as lubricant additives with the addition of 1% into trimellitic acid esters were also tested under the load of 98 N by a microtribometer. The results show that the N′,N′-disubstituted hydrazide compounds has a significant antifriction and antiwear effects, and the friction coefficients of Trimellitate(TMT) with addition of N′,N′-dibutylpentanohydrazide,N′,N′-bis(2-ethylhexyl)pentanoylhydrazide,4-methyl-N′,N′-di-p- methylbenzohydrazide and 4-methyl-N′,N′-diethylbenzoylhydrazide are lower than those of TMT without addition, the friction coefficients of TMT with addition of N′, N′-diethylpentanohydrazide exhibit the biggest downward trend to the minimum value of 0.051 2. The wear volume losses of the steel balls in TMT with addition of the eleven hydrazide compounds are all lower than those without addition. The wear volume loss of the steel ball in TMT with addition of N′,N′-bis(2-ethylhexyl)benzoyl hydrazide is the smallest, which reduces 87.13% compared with that without addition. It is expected to be a green and efficient antifriction lubricant additive.
