imported oil for powering transportation and infrastructure in the future. In this report, we reacted medium‐chain and long‐chain fatty anhydrides (capric, caprylic, lauric, and palmitic) with furfuraldehyde by the Perkin condensation to produce 2‐n‐alkenylfurans. In the second step, the 2‐n‐alkenylfurans were hydrogenated to form 2‐n‐alkyltetrahydrofurans. Basic fuel property testing (melting point
国内生产的生物燃料将来可能有助于减少对进口石油的依赖,从而为运输和基础设施提供动力。在本报告中,我们通过珀金缩合反应使中链和长链脂肪酸酐(癸酸,辛酸,月桂酸和棕榈酸)与糠醛反应生成2- n-烯基呋喃。在第二步中,将2- n-烯基呋喃氢化形成2- n-烷基四氢呋喃。基本燃料特性测试(熔点,密度,运动粘度,衍生十六烷值,和热值)的2- Ñ烷基四氢呋喃表明它们潜在地可用作柴油发动机的燃料。由2-辛基和2-癸基四氢呋喃组成的混合物具有最佳的燃料特性组合,包括低熔点(-39°C),十六烷值高(63.1),闪点高(98.2°C)和低粘度(2.26 mm 2 s -1,40 °C),与2号柴油和生物柴油的规格相比具有优势。
