摘要
烯烃歧化反应广泛用于石油化工和有机合成领域。本文介绍了常用于烯烃交叉歧化反应的多相催化剂,如负载型Re、Mo、W催化剂及其特点,影响催化剂活性的因素,如金属价态、结构、分散度、载体性质及助剂影响等,探讨了烯烃歧化反应的机理及其可能的失活途径。
Olefin metathesis has been widely used in the fields of petrochemical industry and organic synthesis. It can be classified as ring-opening metathesis, ring-opening metathesis polymerization, ring-closing metathesis and crossmetathesis, etc. Recent developments in the heterogeneous catalysts for olefin cross-metathesis are summarized in this review. Much attention has been paid not only to the heterogeneous catalysts based on Re, Mo and W, but also to the effects that may influence the catalyst activity, such as the metal oxidation state, structure and dispersion of the active species, properties of the support and the addition of promoters, etc. The reaction mechanisms and possible deactivation routes are also discussed in detail.
