摘　　要：对反应精馏的环戊二烯二聚过程中 ,伴随的异戊二烯、间戊二烯和环戊二烯反应产生的共二聚物进行了研究。温度是影响共二聚物生成量的主要因素 ,而异戊二烯含量的影响比间戊二烯含量大得多。同时根据试验结果提出了80℃的共二聚反应速率方程。This paper investigates the formation of co dimers by dimerization between isoprene (IP),1,3 pentadine(PD) and cyclopentadiene(CPD) during reaction distillation of C 5 fractions from petroleum cracking.Temperature is the primary factor influencing the production of dimers.The effect of the concentration of IP on the yield of dimers is more significant than the concentration of PD.From experimental data,the kinetic equation for the dimers at 80℃ is derived.
