摘要

本文综述了正丁烯骨架异构化与异丁烯骨架异构化最相关的几个方面:活性位点的性质、骨架异构化的主要机理以及骨架异构化与正丁烷骨架异构化的关系。结果表明，正丁烯骨架异构化的主要机理是单分子异构化(与丁烷异构化相反)，并且需要Br⊘嵌套酸(OH)活性位点。分子筛和分子筛的形状选择性影响分子筛的选择性和催化稳定性。这些影响是在对流行机制的了解的基础上解释的。

Skeletal Isomerization of n-Butene

Abstract In this review, the most relevant aspects of skeletal isomerization of n-butene to isobutene are discussed: the nature of the active sites, the prevailing mechanism of the skeletal isomerization, and the relation of this to that of n-butane. It is concluded that the prevailing mechanism of skeletal isomerization of n-butene is monomolecular (in contrast to butane isomerization) and requires Br⊘nsted acid (OH) active sites. The selectivity and catalytic stability can be influenced by the shape selectivity of zeolites and zeotypes. These effects are explained on the basis of the knowledge on the prevailing mechanism.
