产品应用

• 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。
