摘　　要：以脂肪酸、β羟乙基乙二胺、硼酸按不同比例分别合成了四种脂肪酸咪唑啉硼酸单酯和三酯。经ＩＲ、１ＨＮＭＲ和元素分析证明结构正确。用四球试验机评价了两种化合物在水中的摩擦学性能。结果表明这些化合物在水中具有良好的承载能力和抗磨性能。Four imidazoline borates were synthesized with two kinds of fatty acid,N hydroxyethyl ethylenediamine,boric acid according to the different ratio of reaction materials.Their structrues proved correct by means of IR, 1HNMR,element analysis.The tribological properties of these compounds were evaluated with the help of a four ball test machine.The tribological test results showed that the imidazoline borates had good load carrying capacity and antiwear property,and the antiwear mechanisms were preliminarily discussed.
