摘要
环烯烃聚合物是一类性能优良的热塑性工程塑料,其单体降冰片烯的制备工艺复杂且存在工程安全问题,长期被少数企业垄断,价格昂贵.关于降冰片烯合成的报道多为专利,年代跨度大且缺乏系统性综述.本文围绕降冰片烯的制备过程,首先对双环戊二烯裂解制备环戊二烯工艺进行了总结,按照液相法、气相法进行分类和比较,分析了两种方法在反应温度、停留时间、反应设备、稀释剂和阻聚剂等方面的区别,探讨了两种方法的优劣势.之后总结了液相法、气相法或超临界法下加成反应制备降冰片烯的工艺特点,分析了不同制备方法在温度、压力、反应器形式、稀释剂等方面的区别和优劣势,为降冰片烯制备工艺的设计与优化提供了参考借鉴.最后,对多环降冰片烯衍生物的制备工艺进行了介绍.
Abstract
Cyclic olefin copolymers are a class of high-performance thermoplastic engineering plastics.The preparation technology of monomer norbornene is complex and poses engineering safety challenges,leading to a long-term monopoly by a few enterprises and exorbitant prices.Reports on norbornene synthesis are mostly found in patents with spanning various periods and lacking systematic reviews.This review first summarized the cracking process of dicyclopentadiene for the preparation of cyclopentadiene and compared the liquid-phase with gas-phase methods.Their differences in temperature,residence time,equipment,diluents and inhibitors were analyzed,and the advantages and disadvantages of both methods were discussed.Subsequently,the characteristics of norbornene preparation through addition reactions using liquid-phase,gas-phase and supercritical methods were reviewed.The distinctions and pros and cons of different preparation methods in terms of temperature,pressure,equipment,diluents and other aspects were analyzed,providing valuable reference and guidance for the design and optimization of norbornene preparation processes.Finally,the preparation process of polycyclic norbornene derivatives was introduced.
