摘要
本文综述了四环十二碳烯的制备方法、合成工艺优化和市场前景。四环十二碳烯可代替降冰片烯作为环烯烃单体,用于生产环烯烃共聚物(COC)和环烯烃聚合物(COP),使其拥有更高的玻璃化转变温度和更强的韧性。四环十二碳烯的合成原料为双环戊二烯、降冰片烯和乙烯,通过Diels-Alder反应在高温和高压的条件下制备。四环十二碳烯的合成工艺包括反应工段和精馏工段,本文从降低或除去副产物和防止降冰片烯在管道中凝固两个方向介绍了国内外工艺改进方法。最后,结合国际和国内市场现状,分析了四环十二碳烯的市场前景,同时也提出未来的工艺优化方向。
This paper reviewed the preparation method,synthesis process,process improvement,and market prospect of tetracyclododecene.Tetracyclododecene can replace norbornene as the cyclic olefin monomer for the production of cyclic olefin copolymers(COC)and cyclic olefin polymers(COP),giving it a higher glass transition temperature and stronger toughness.The main raw materials for synthesis of tetracyclic dodecene were dicyclopentadiene,norbornene and ethylene,which were prepared by Diels-Alder reaction under high temperature and pressure.The synthesis process of tetracyclododecene included reaction section and rectification section.This paper introduceed the process improvement methods focusing on reducing or removing by-products and preventing norbornene from solidifying in the pipeline.Finally,based on the current international and domestic market conditions,the market prospects of tetracyclododecene were analyzed,and future process optimization directions were proposed.
