摘要

近年来，随着三元乙丙橡胶的广泛应用，作为其首选第三单体的亚乙基降冰片烯（ENB）越来越受到关注。综述了ENB的反应机理、合成工艺、生产情况及市场动向。在反应机理方面主要包括先由双环戊二烯在高温下裂解成的环戊二烯与丁二烯经Diels-Alder反应生成中间体乙烯基降冰片烯（VNB），再经其异构化反应制得亚乙基降冰片烯。重点阐述了乙烯基降冰片烯合成阶段副反应控制的工艺优化，以及VNB异构化阶段不同类型催化剂的影响等。

Abstract

Regarding to the ongoing demand for poly(ethylene propylene diene monomer) (EPDM)

ethylidene norbornene (ENB) as its co-monomer has attracted important attention. In this paper

synthesis mechanism and technology

production status and market trend of ENB are reviewed. The discussion about synthesis processes of ethylidene norbornene is divided into two parts

one is process optimization for side reaction control in the part of vinyl norbornene (VNB) synthesis by Diels-Alder reaction between butadiene and cyclopentadiene obtained from (di)cyclopentadiene by high temperature degradation

the other is influence of different types of catalysts in the VNB isomerization process.
