摘要

介绍了异丁烯齐聚反应机理和异丁烯齐聚反应产物的利用，重点介绍了可以替代混合C₄馏分中异丁烯醚化生产MTBE的工艺、异丁烯选择性齐聚反应不同类型催化剂的性能比较等研究现状，从经济、技术和发展等方面对混合C₄馏分中异丁烯选择性齐聚提出了建议。

Abstract

The reaction mechanism of isobutylene oligomerization and the utilization of oligomeric products are introduced,with emphasis on the process that can replace the etherification process in which isobutylene in mixed C₄ fractions is etherified to produce MTBE,and the comparison of the performance of different catalysts for selective oligomerization of isobutylene.The suggestions about selective oligomerization of isobutylene in mixed C₄ fractions are given from economy,technology and development aspects.
