| 中文摘要: |
| γ-戊内酯可应用于食品添加剂、燃料添加剂、溶剂、汽油、柴油以及多种化工中间体的合成，由于其上游原料乙酰丙酸是生物质基的平台化合物且其已被工业化生产，因此发展其高效、可循环使用的催化合成新体系是近年来生物质催化转化的研究热点之一。均相催化剂体系具有活性高的优点但难以实现催化剂的回收与重复利用，本文着重从贵金属催化剂（钯、钌、金等）和非贵金属催化剂（镍、铜）两个方面介绍多相催化剂体系的研究进展。通过综述贵金属和非贵金属催化剂体系的若干实例，指出贵金属催化剂在催化剂价格和催化剂稳定性上的严重不足。由此，开发廉价、具有高活性和稳定的非贵金属催化剂具有重要意义。 |
| 英文摘要: |
| γ-Valerolactone (GVL) has been identified as versatile building blocks in the preparation of numerous fine chemicals. It could also be used as additives in fuel, solvents and food due to its unique physical and chemical properties. This review summarized the different catalyst systems of the GVL synthesis and divided them into homogeneous and heterogeneous systems. Additionally, we would like to focus on the heterogeneous catalyst system, since homogeneous catalysts have obvious drawbacks in recycling and reusability. However, previously reported noble metal catalysts also have some disadvantage in their high cost and instability. Therefore, developing the economical non-noble catalyst system with high efficiency and stability has practical values. |
