烯烃复分解为重要的石油化工、石油化工、聚合物和特种化学品开辟了新的工业路线。烯烃复分解在石化领域最重要的应用是烯烃转化技术(OCT)工艺(最初是菲利普斯三烯烃工艺)和壳牌高碳烯烃工艺(SHOP)。特别是，具有集成复分解装置的石脑油蒸汽裂解装置是通过OCT工艺生产丙烯的一种有趣的替代方案，因为全球对丙烯的高需求超过了传统来源的供应。在聚合物领域，环烯烃开环歧化聚合(ROMP)是制备具有特殊性能聚合物的一种很有吸引力的方法。一些涉及ROMP的工业工艺已被开发并投入实践，如环辛烯、降冰片烯和双环戊二烯的ROMP，导致了有用的聚合物。天然脂肪和油及其衍生物的化合作用为油脂化学工业的未来发展提供了可能性，为可持续的化学工业做出了贡献。此外，鉴于新的金属-卡宾歧化催化剂，特别是耐官能团的明确定义的基于Ru的催化剂，预计在精细化学中，歧化反应将很快成为合成农用化学品、昆虫信息素、香料、医药中间体等的工具。(C)2003 Elsevier B.V.保留所有权利。
Olefin metathesis opens up new industrial routes to important petrochemicals, oleochemicals, polymers and specialty chemicals. The most important applications of olefin metathesis in the field of petrochemicals are the olefins conversion technology (OCT) process (originally the Phillips triolefin process) and the Shell higher olefins process (SHOP).In particular, naphtha steam crackers with an integrated metathesis unit are an interesting alternative for producing propene via the OCT process, as a high global demand for propene outpaces supply from conventional sources. In the polymer field, ring-opening metathesis polymerisation (ROMP) of cycloalkenes is an attractive process for making polymers possessing special properties. Several industrial processes involving ROMP have been developed and brought into practice, such as the ROMP of cyclooctene, norbornene and dicyclopentadiene, leading to useful polymers. Metathesis of natural fats and oils and their derivatives offers possibilities for future developments in the oleochemical industry, providing a contribution to a sustainable chemical industry. Moreover, in the light of the new metal-carbene metathesis catalysts, in particular the functional-group-tolerant well-defined ruthenium-based catalysts, it is to be expected that in the fine chemistry the metathesis reaction will soon find its way as a tool for the synthesis of agrochemicals, insect pheromones, fragrances, pharmaceutical intermediates, etc. (C) 2003 Elsevier B.V.
