摘　　要：本研究采用正己烷为溶剂,催化剂采用级配装填技术,一步法合成挂式四氢双环戊二烯(JP-10),通过FTIR、UV-vis、TG-DTA、1H-NMR对其进行检测和表征。FTIR揭示了JP-10分子内部存在亚甲基、次甲基和骨架环。UV-vis检测出了JP-10在292.7、418.8、575.2 nm有三个吸收峰,分别为JP-10分子中的各类π→π*的电子跃迁产生的,JP-10分子中存在三类五元环和一个六元环,叠加成的化合物。TG-DTA检测出在193.1℃分别出现了吸收峰,为JP-10分解产生的,JP-10分解温度偏高,是理想的高密度烃燃料。根据1 H-NMR氢谱谱图和H原子的化学位移,推断其氢原子数目和位置,分子中各个氢核对应所归属的吸收峰,和JP-10的分子结构相吻合。In the study,n-hexane was used as solvent,and the catalyst was prepared by graded loading technology. Exo-Tetrahydrodicyclopentadiene( JP-10) was prepared by the one-step method. JP-10 was detected by FTIR,UV-vis,XRD,TG-DTA,1H-NMR. The presence of methylene,methine and backbone rings in the JP-10 molecule was revealed by FTIR. There were three absorption peaks at 292. 7,418. 8,and 575. 2 nm detected by UV-vis due to various electronic transitions of π→π~* in JP-10 molecules. The compound formed by the combination of three kinds of five-member and a six-member ring. The phase composition and qualitative identification of JP-10 structure were completed. There was an absorption peak detected by TG-DTA at 193. 1 ℃ due to the decomposition of JP-10. The decomposition temperature of JP-10 was high,so JP-10 was an ideal high-density hydrocarbon fuel. There were 16 hydrogen atoms in th molecules,consistent with their formulas detected by ~1H-NMR. Each hydrogen nucleus in the molecule was corresponded to the assigned absorption peak.
