Biolubricants are becoming interesting alternatives to mineral lubricants. Despite their advantages, development of lubricants from vegetable oils may compete with food production, turning their use impractical due to socio‐economic aspects. Here, cardanol is used as raw material in the synthesis of novel biolubricants under environmentally friendly conditions. These compounds are characterized by NMR and Fourier transform infrared spectroscopy. Thermal‐oxidative studies show the elevated stability and higher onset oxidative temperatures. Tribological analyses performed under high‐frequency linear‐oscillation motion indicate lower coefficients of friction and wear rates compared to a synthetic oil. Therefore, cardanol, under simple, fast, and sustainable processes can be transformed into valuable alternatives for petroleum‐based lubricants.

在环境友好的过程中从农业工业残留物中开发完全基于生物的润滑剂

生物润滑剂正在成为矿物润滑剂的有趣替代品。尽管具有优势，但从植物油中开发润滑剂可能会与食品生产竞争，由于社会经济方面的原因，使它们的使用变得不切实际。在这里，腰果酚被用作在环保条件下合成新型生物润滑剂的原料。这些化合物通过NMR和傅立叶变换红外光谱法表征。热氧化研究显示出较高的稳定性和较高的起始氧化温度。在高频线性振荡运动下进行的摩擦学分析表明，与合成油相比，摩擦系数和磨损率更低。因此，腰果酚在简单，快速和可持续的过程中可以转化为石油基润滑剂的有价值的替代品。
