The depletion of petroleum resources and the intensification of environmental problems have necessitated the development of renewable products from bio-based chemicals instead of petroleum resources. Herein, a new kind of ester lubricating oil, isooctyl furan dicarboxylate (isooctyl-FD), was prepared from bio-based 2, 5-furandicarboxylic acid. The structure of isooctyl-FD was evaluated using nuclear magnetic resonance imaging and high-resolution mass spectroscopy. Its physicochemical and tribological properties including thermal and oxidation stabilities, flash point and pour point, viscosity and viscosity index, and friction-reducing and anti-wear properties were systematically evaluated. The results show that isooctyl-FD has comparable thermal and oxidation stability to the synthetic ester lubricating oil, isooctyl sebacate (isooctyl-S). Its friction-reducing and anti-wear properties are superior to isooctyl-S; however, its viscosity-temperature and low-temperature properties are inferior to isooctyl-S.

由生物基2,5-呋喃二甲酸制备的酯油的润滑性能

石油资源的枯竭和环境问题的加剧，使得必须开发由生物基化学品替代石油资源的可再生产品。在此，从生物基2,5-呋喃二甲酸制备了一种新型的酯润滑油，呋喃二羧酸异辛酯（isooctyl-FD）。使用核磁共振成像和高分辨率质谱法评估了异辛基-FD的结构。系统地评估了其理化和摩擦学性能，包括热稳定性和氧化稳定性，闪点和倾点，粘度和粘度指数以及减摩和抗磨性能。结果表明，异辛基-FD具有与合成酯润滑油癸二酸异辛酯（isooctyl-S）相当的热稳定性和氧化稳定性。它的减少摩擦和抗磨性能优于异辛基-S；但是，其粘度-温度和低温性能不如异辛基-S。
