摘　　要：用异丁烯二聚物和正丁烯二聚物为原料合成了辛基酚。比较了两种烯烃的反应活性和产物结构。利用正丁烯二聚物的各种组份测定了不同结构烯烃烷基化反应的相对话性。结果表明，不同结构的辛烯对苯酚的烷基化速度不同，异丁烯二聚物的烷基化速度大于正丁烯二聚物的烷基化速度；异丁烯二聚体得到的辛基酚的对位含量大于正丁烯二聚物得到的辛基酚的对位含量。Octylphenols are synthesised by alkylating phenol with dimers of isobutene and dimers ofnormal butenes which in turnare prepared by oligomerization of iso- and n-butenes respectively.The structure of octylphenols and the reaction activity of octenes as alkylating agents ofphenol are investigated.The relative activity of various structures of octenes is determined.
