摘要

以双环戊二烯和茚为原料,经D-A反应及催化加氢合成高密度烃燃料四环[9.2.1.02,10.13.8]十四烷(TDTD).采用裂解器及色质联用进行了四环[9.2.1.02.10.1 3.8]十四烷的热裂解研究,考察了不同温度及时间对热裂解转化率的影响,结果显示,温度对转化率影响较大.分析裂解产物,推测了裂解机理,以裂解温度与转化率的关系计算得到热裂解反应动力学方程,裂解反应活化能表明,四环[9.2.1.02.10.1 3,8]十四烷较JP-10燃料易裂解.%As a high density hydrocarbon fuel, tetracyclo[9. 2. 1. 02,10.13.8] tetradecane was synthesized from dicyclopentadiene and indene by D-A reaction and hydrogenation. Thermal decomposition of tetracyclo [9. 2. 1. 02,10.13,8]tetradecane was studied in a decomposition reactor, and the products were detected by gas chromatography-mass spectroscopy. The conversion of tetracyclo [9. 2. 1. 02,10.13,8] tetradecane at different temperature and time was investigated. The results indicated that the effect of temperature was superior to other factors in this reaction. A primary mechanism was also presumed according to the main products of the reaction. Finally, the kinetic equation of thermal decomposition was obtained. The activation energy derived from kinetic data indicated that tetracyclo [9. 2. 1. 02,10.13,8] tetradecane can decompose more easily than JP-10 fuel.
