The effects of dicyclopentadiene (DCPD) mass fraction, reaction temperature, reaction pressure and reaction time on DCPD conversion and NB selectivity are investigated in a stirred reactor with norbornene (NB) as the research object. According to the experimental results, the optimum reaction conditions are determined to be a DCPD solution mass fraction of 20%, a reaction time of 4 h, and a reaction pressure of 7.0 MPa, resulting in DCPD conversion and NB selectivity reaching 98.0% and 96.5%, respectively. In addition, the reaction kinetics of norbornene synthesis is studied in a stirred reactor. Through fitting the experimental data, the kinetic parameters of the main and side reactions during the synthesis of norbornene are derived. The activation energies E 1 and E -1 of the main reactions are found to be 98.93 kJ/mol and 111.74 kJ/mol, respectively. Meanwhile, the activation energies E 2 and E -2 of the side reaction are determined to be 86.46 kJ/mol and 161.87 kJ/mol, respectively. Through statistical tests and comparison of experimental and calculated values of CPD conversion and NB selectivity, the model established provides a theoretical framework for understanding norbornene synthesis and optimizing the process.
