合成5种二苯并-26-冠-8衍生物，通过核磁共振氢谱、碳谱、质谱对其结构进行表征，采用四球试验机考察其在锂基脂中的摩擦学性能。结果表明，冠醚化合物能显著提高基础锂基脂的承载能力和抗磨性能，其中具有强极性基团（羟基）并含有大环冠醚空腔的冠醚衍生物，对金属表面有较强的相互作用，从而具有更好的抗磨和极压性能。
閤成5種二苯併-26-冠-8衍生物，通過覈磁共振氫譜、碳譜、質譜對其結構進行錶徵，採用四毬試驗機攷察其在鋰基脂中的摩抆學性能。結果錶明，冠醚化閤物能顯著提高基礎鋰基脂的承載能力和抗磨性能，其中具有彊極性基糰（羥基）併含有大環冠醚空腔的冠醚衍生物，對金屬錶麵有較彊的相互作用，從而具有更好的抗磨和極壓性能。

Five BMP26C8 derivatives were synthesized,and their structures were characterized by 1 H NMR,13 C NMR and ESI-MS.The tribological properties of the macrocyclic crown ether compounds in lithium-based grease were evaluated on friction testers.The results show that the macrocyclic crown compounds can improve carrying capacity and anti-wear properties of the lithium-based grease.The crown ether derivative with polar groups(hydroxyl)possesses strong interaction with metal surface,and exhibits better performance as an extreme pressure and anti-wear additive.
