二聚环戊二烯用途
环戊二烯二聚体（或环戊二烯）的主要用途有：
（1）用作乙烯-丙烯二元共聚物（EPDM）的第三组份；
（2）用作合成乙叉降冰片烯（ENB）的原料；
（3）与顺丁烯二酸酐反应得到降冰片烯二酸酐，用作环氧树脂固化剂、聚酯树脂、醇酸树脂、杀虫剂的原料；
（4）环戊二烯的六氯化物——六氯环戊二烯，与顺酐反应得到的六氯化内亚甲基的氢化邻苯二甲酸酐，用作合成树脂的阻燃剂；
（5）二聚环戊二烯用于桐油、亚麻仁油、大豆油、鱼油等的改性，可加快干燥性，提高耐水、耐碱性；（6）二聚环戊二烯树脂可用作橡胶粘合剂、压敏粘接剂、热溶粘合剂、油墨、涂料等；
（7）二聚环戊二烯氧化物可用作注射成型和层压成型树脂；
（8）环戊二烯部分加氢得到的环戊烯，再聚合制得1,5-反式聚环戊烯；
（9）环戊二烯是生产艾氏剂、荻氏剂类杀虫剂原料；
（10）环戊二烯还用于药物合成。例如胃长乐的中间体α-环戊二烯基扁桃酸甲酯，由苯乙酮酸甲酯与环戊二烯加成而得；
（11）加氢后用作高能燃料。
高分子聚合反应的单体。用于制造合成橡胶胶黏剂、医药、农药、合成香料等产品。与马来酸的共聚物可用作涂料、胶黏剂；与顺酐的共聚物可用作纸张施胶剂；与萜烯油的共聚物可制成胶版印刷墨水；与间戊二烯的共聚物可用作橡胶补强剂。本品的四氢化物是火箭及喷气发动机的高能燃料。

二聚环戊二烯制备
将煤焦油的轻苯馏分蒸馏，切取＜70℃的苯头馏分，其中含环戊二烯约30%，再经加热，聚合，蒸馏得成品双环戊二烯。以烃裂解工业中的C5馏分为原料，经加热二聚，然后进行减压蒸馏分离而得。其次，以环戊二烯为原料，经二聚亦可制得。工艺流程： （1）以C5馏分为原料，首先把C5馏分加热到80-120℃，使环戊二烯发生二聚。接着进行精馏，由塔底分离得到双环戊二烯馏分。因为该馏分中除环戊二烯、异戊间干烯等外，还混有二烯烃类。把它加热到170℃以上，只有双环戊二烯优先分解、精馏。得到的环戊二烯通过热聚合、精馏，则得到双环戊二烯。 （2）可采用热聚合的方法使环戊二烯转变为沸点为170℃的二聚体，然后用蒸馏法提纯。二聚反应在70℃时进行最完全但反应过程很缓慢。采用加热全回流16-18h，再升温至取前馏分（82℃以下）、苯馏分（82℃以上），直至釜温达到110℃为止。釜底残留物为二聚环戊二烯，含量约60%，再经减压蒸馏，可得含量≥99%的二聚体。
