Abstract With the rapid development of spacecraft such as rocket, it is increasingly important to develop high-energy and sustainable fuels. Biofuels synthesized from biomass derivatives provide great convenience for sustainable development. In this work, we reported a route for synthesis of high-energy cyclopropane bio-kerosene by cyclopropanation of myrcene with zinc carbenoid. The reaction conditions including reaction time, reaction temperature, solvent and molar ratio were optimized. Finally, a tricyclic cyclopropane bio-kerosene was synthesized with 69.8% yield under optimum conditions (i.e. zinc carbenoid synthesis temperature of −15 °C, cyclopropanation temperature of 25 °C and solvent of dichloromethane). Importantly, this bio-kerosene possesses a high specific impulse of 328.25 s, much better than the commercial rocket kerosene RP-1, as well as a high net-heat-value of 43.4 MJ/kg and good low-temperature properties.

月桂烯环丙烷化合成高能火箭生物煤油

摘要 随着火箭等航天器的飞速发展，开发高能、可持续燃料越来越重要。由生物质衍生物合成的生物燃料为可持续发展提供了极大的便利。在这项工作中，我们报道了一种通过月桂烯与卡宾酸锌环丙烷化合成高能环丙烷生物煤油的路线。对反应时间、反应温度、溶剂和摩尔比等反应条件进行了优化。最后，在最佳条件下（即锌卡宾合成温度为-15℃，环丙烷化温度为25℃，溶剂为二氯甲烷）合成了三环环丙烷生物煤油，产率为69.8%。重要的是，这种生物煤油具有 328.25 s 的高比冲，远优于商业火箭煤油 RP-1，
