In this work, a series choline monocarboxylate ionic liquids ([Ch][MA] ILs) were synthesized. The physicochemical properties and lubricating efficiency of the ILs on copper and aluminum discs were systematically investigated. At the same time, their ecotoxicity was explored on aquatic organisms. In comparison with 1‐butyl‐3‐methyl imidazolium tetrafluoroborate (L‐B104), which is a kind of traditional IL, [Ch][MA] ILs exhibited excellent lubricating properties and low toxicities, thus can be considered as environmentally friendly lubricants in tribology.

胆碱单羧酸盐离子液体润滑剂的生态毒性和摩擦学性能

在这项工作中，合成了一系列胆碱单羧酸盐离子液体（[Ch] [MA] ILs）。系统研究了离子液体在铜和铝圆盘上的物理化学性质和润滑效率。同时，还研究了它们对水生生物的生态毒性。与传统的IL的1-丁基-3-甲基咪唑四氟硼酸盐（L-B104）相比，[Ch] [MA] IL表现出优异的润滑性能和低毒性，因此可以被认为是环保的润滑剂。摩擦学。
