1,3-丁二烯与甲醇调聚工艺及其催化剂研究进展
Research progress in 1,3-butadiene-methanol telomerization process and relevant catalysts
介绍了1,3-丁二烯与甲醇调聚反应在高纯度1-辛烯合成工艺中的应用以及调聚反应催化剂的研究进展。目前国内外对均相催化剂的研究较为广泛,虽然均相氮杂环卡宾配体在丁二烯调聚反应中表现出超高的反应活性和优异的目标产物选择性,但是不及膦配体更适用于工业应用,且两者仍面临催化剂体系分离回收利用难及稳定性差等问题,非均相催化剂因能降低金属钯的流失率,实现催化剂的循环利用,近年来备受关注。实现1,3-丁二烯与甲醇高效、高稳定性非均相调聚过程是目前该领域亟待解决的难题。
The research progress on the application of 1,3-butadiene-methanol telomerization in the synthesis of high purity 1-octene as well as the telomerization catalyst are introduced.Although homogenous N-heterocyclic carbene ligands show extremely high reactivity and excellent target product selectivity in the 1,3-butadiene-methanol telomerization,they are less suitable for industrial applications than phosphine ligands.Both N-heterocyclic carbene ligands and phosphine ligands still face the problems such as separation and recycling difficulties,and poor stability.Heterogeneous catalysts have attracted much attention in recent years because they can reduce the loss rate of palladium and can be recycled and re-utilized.It is an urgent problem to realize the highly efficient and stable heterogeneous 1,3-butadiene-methanol telomerization process.
