Abstract
Exo-tetrahydrodicyclopentadiene (exo-THDCPD) is an important high density liquid hydrocarbon fuel. To improve the synthesis efficiency of exo-THDCPD, a new process of continuous preparation of exo-THDCPD, including the cascade of two reactors (continuous-flow bubbling hydrogenation reactor and continuous-flow isomerization tank reactor), namely the cascade of two processes (dicyclopentadiene (DCPD) was hydrogenated to endo-THDCPD over Pd/C catalyst and the endo-THDCPD was isomerized to exo-THDCPD over AlCl3 catalyst) was studied. The liquid-phase continuous-flow preparation of exo-THDCPD was realized. Results show that the optimum liquid-phase continuous-flow process conditions of preparing exo-THDCPD are determined as: weight hourly space velocity(WHSV), 2.4 h-1; hydrogenation pressure(pH), 0.1 MPa; H2 gas flow rate, 80 mL·min-1; DCPD concentration (CDCPD), 0.76 mol·L-1; hydrogenation reaction temperature: 30℃; isomerization; reaction temperature, 70℃; conversion of DCPD, 100% and yield of exo-THDCPD, 92.5%.
