摘　　要：分别以4-甲基-1-戊烯、1-辛烯、1-己烯作为目标α-烯烃,叙述了在醇脱水合成α-烯烃领域的研究工作,重点介绍了催化剂的设计合成和影响产物中α-烯烃选择性的因素。从高碳醇出发经选择性脱水合成长链α-烯烃,特别是合成单体4-甲基-1-戊烯具有一定的工业应用前景。The rapid development of polyolefin industry has brought a huge demand for long-chainα-olefins.Synthesis of long-chainα-olefins by dehydration of higher alcohols has been found to be a good option.This paper describes the research on alcohol dehydration over the years,targeting several importantα-olefins as products,such as 4-methyl-1-pentene,1-octene,and 1-hexene.The design and synthetic process of the catalysts are described in detail.Meanwhile,the factors that affect the selectivity ofα-olefins are focused and analyzed.It should be pointed out that the synthesis of long-chainα-olefins by selective dehydration of higher alcohols has broad application prospects in industry,which provides a solution for the production of 4-methyl-1-pentene.
