The new progress in catalytic epoxidation reaction research of terpenes was reviewed.
介绍了萜烯催化环氧化反应的最新进展,了解到近年来在萜烯中双键选择性环氧化研究的焦点集中在非均相催化剂的制备上,因此,如果综合考虑各种催化体系存在的优缺点,结合具体条件予以优化和改进,将能获得更为理想的环氧化结果。
补充资料：萜
| 萜 terpene 通式为（C5H8）n的链状或环状烯烃类及其含氧化合物。大多数存在于植物的精油和树脂中，例如，柠檬油中的柠檬烯、松节油中的a-和β-蒎烯、香樟中的樟脑等。根据间异戊二烯单元C5H8的数目，萜可分以下几类（见下栏表）。
萜一般为无色液体。比水轻，有香味。不溶于水，溶于乙醇。萜的含氧化合物如柠檬醛、薄荷脑、樟脑等都很重要。 |
