| 摘 要： | 采用工业粗品双环戊二烯（DCPD）为原料制备高纯度的环戊二烯（CPD）,通过SE-30石英毛细管柱对原料和解聚后得到的环戊二烯进行气相色谱分析。对原料进行提纯,以120℃进行热二聚,最后在175-180℃进行解聚,得到的新鲜环戊二烯的纯度可达到99%以上。解聚后得到的环戊二烯在室温下极易发生聚合反应,长时间放置纯度大幅度降低,应立即使用。

| Abstract: | The high purity cyclopentadiene(CPD) was prepared by using industrial raw dicyclopentadiene(DCPD).The raw materials and cyclopentadiene obtained by the depolymerization of dicyclopentadiene were analyzed by gas chromatography with SE-30 quartz capillary column.The raw material was purified,then was carried out thermal dimerization at 120 ℃ and depolymerization at 175~180 ℃.The purity of cyclopentadiene obtained by this way is more than 99%.Cyclopentadiene is very easy to polymerize and the purity of it after long time decreases remarkably,so it must be used as soon as. |
