| 摘 要： | 由于甲基叔丁基醚(MTBE)对水源的污染，它作为汽油添加剂的应用受到环保限制，并对其生产和应用前景带来消极影响。MTBE经裂解、二聚和加氢生产异辛烷成为国外现有MTBE装置转产的主要途径。本文对异丁烯二聚催化剂、反应活性位、机理及动力学研究成果进行了综述，试图解释在异丁烯二聚时，加入的叔丁醇对二聚反应选择性提高的作用机理，为今后二聚反应的研究提供参考。

| Abstract: | Because methyl tert-butyl ether(MTBE) is soluble in water and has been occasionally found its way into ground water from leaking storage tanks,MTBE is environmentally limited as gasoline additive and its production and application prospects are negatively affected.Producing isooctane by MTBE decomposition,dimerization of isobutene(IB) and hydrogenation of diisobutene became the main way for the exiting MTBE units to produce other products abroad.The catalysts for IB dimerization,reactive site,reactive mechanism and dynamics research date are reviewed in this paper.The mechanism of selectivity enhancing by adding tert-butyl alcohol during IB dimerization is explained and the reference for the study of dimerization is provided afterwards. |
