摘要
ε-己内酯是一种重要的有机中间体,也是合成生物可降解材料聚己内酯、高性能材料聚氨酯等重要聚合物的单体,具有非常广阔的应用前景.在目前已报道的合成方法中,以环己酮为原料,采用过氧化氢氧化法合成ε-己内酯是一种新型的绿色合成方法.在此方法中,由于过氧化氢的活性较低,高效催化剂的引入至关重要.从均相催化剂和非均相催化剂两个角度,综述了使用过氧化氢氧化法合成ε-己内酯的研究进展,通过实例,对比分析不同催化剂的优势和劣势,指出了杂多酸负载多相化策略不仅保留了杂多酸催化剂活性高、选择性好的优点,同时解决了催化剂的分离问题,是一种发展前景较好的催化剂.最后总结了ε-己内酯的应用市场及产业化开发的现状,并展望了在未来研究者们应重点关注的问题.
Abstract
ε-Caprolactone is an important organic intermediate,which is the monomer for synthesizing biodegradable material polycaprolactone,as well as the monomer for synthesizing other polymers such as high-performance polyurethane.ε-Caprolactone has very broad application prospects.Among the reported synthesis methods,the synthesis method with cyclohexanone as raw material and hydrogen peroxide as oxidant is a new type of green ε-caprolactone synthesis method.In this method,the introduction of efficient catalysts is crucial due to the low activity of hydrogen peroxide.In this article,the research progress in the synthesis of ε-caprolactone using hydrogen peroxide oxidation method was reviewed from the perspectives of homogeneous and heterogeneous catalysts.Through examples,the advantages and disadvantages of different catalysts were compared and analyzed.It was pointed out that the heterogeneous catalyst supported by heteropolymetalate not only retained the advantages of high activity and good selectivity of heteropolymetalate catalyst,but also solved the problem of catalyst separation,which had a good development prospect.Finally,by summarizing the application market and industrial development status of ε-caprolactone,suggestions were given for researchers to focus on in future.
