摘要：对在常压下以油酸和乙二胺为原料在溶剂二甲苯中合成油酸酰胺实验的方法进行研究，通过正交试验得到了最佳的工艺条件为：反应时间2h，投料比1：1.4，反应温度120±5℃。利用红外光谱仪分析产物，并在环-块式摩擦磨损试验机和四球试验机上，测定了油酸酰胺添加到基础油后的摩擦磨损性能，对油酸酰胺添加量对这些性能的影响进行了考察。结果表明，含油酸酰胺1.5%（wt%）时，为最佳值。测定基础油、添加1.5%（wt%）油酸酰胺的基础油、添加T202的基础油三者的最大无卡咬负荷PB，结果表明添加T202后基础油的PB最大。最后测定油酸酰胺与T202复配后的摩擦化学性能以及两者的添加量对基础油的摩擦磨损性能的影响，结果表明，当添加1.5%（wt%）油酸酰胺和添加1%（wt%）T202复配时，润滑油的抗磨效果最佳。4568

TRIBOLOGICAL CHARACTERISTICS AND SYNTHESIS ON OLEIC AMIDE
ABSTRACT：Oleic amide was synthesized by oleic acid and ethylenediamide. The influences of some factors on the synthesis process were studied thorough orthogonal experiment. The optimal reaction conditions were chosen through orthogonal test that reaction time was 3 h, the molar ratio of oleic acid to ethylenediamide was 1：1.4, reaction temperature was 120±5℃. Its chemical structure was identified by IR spectra. Determine the friction and wear properties of the oleic amide added to base oil in the ring-block friction and wear testing machine and four-ball tester. Results showed that the best value of oleic amide is 1.5% (wt%). Determine the largest non-card bite load (PB) of 32# base oil, adding 1.5%(wt%) of oleic amide in the 32# base oil and adding the T202 base oil, the results showed that the PB of base oil after adding T202 is maximum. Finally, determine the chemical friction about the compound of oleic amide and T202 and the friction and wear performance impact of these two adding amount of base oil, the results show that when add 1.5%(wt%) of oleic amide and add 1%(wt%) of T202 compound, the anti-wear effect of lubricant is best.
