Under high temperature and pressure, a continuous tubular reactor was successfully utilized to investigate the kinetics of 5-vinyl-2-norbornene (VNB) production. The process involved multiple cycloaddition reactions between cyclopentadiene (CPD) and 1,3-butadiene (BD). The results, spanning a wide range of operating conditions, indicate that higher temperature (180°C) and proper residence time (72 min) were conducive to efficient synthesis of VNB. The apparent kinetic parameters, including activation energies and pre-exponential factors, were acquired by fitting experimental data under integral operating conditions. The kinetic model was proven effective from a practical point of view in predicting the concentration changes of each product in the range 140 to 180°C and 30 to 80 wt.% concentration. This work provides a solid basis for the optimization of the VNB synthesis process.

环戊二烯与1,3-丁二烯合成5-乙烯基-2-降冰片烯环加成反应的动力学模型

在高温高压下，成功地利用连续管式反应器研究了 5-乙烯基-2-降冰片烯（VNB）生产的动力学。该过程涉及环戊二烯（CPD）和1,3-丁二烯（BD）之间的多次环加成反应。涵盖各种操作条件的结果表明，较高的温度（180°C）和适当的停留时间（72 分钟）有利于 VNB 的高效合成。表观动力学参数，包括活化能和指前因子，是通过在积分操作条件下拟合实验数据获得的。从实践的角度来看，该动力学模型在预测 140 至 180°C 范围内和 30 至 80 wt.% 浓度范围内每种产品的浓度变化方面被证明是有效的。该工作为VNB合成工艺的优化提供了坚实的基础。
