摘要: 在众多生物质平台分子中，γ-戊内酯（GVL）作为一种新型的生物质基化合物具有广泛的应用价值。首先介绍了由生物质平台分子乙酰丙酸（LA）及其酯类通过氢化作用制备GVL的反应途径及其最新研究进展，在这个反应过程中，氢源对不同催化体系有重要的影响，因此，着重归纳总结了非均相催化剂（氢源：氢气、甲酸和醇类），在多种类型催化体系下催化合成GVL的合成路线和方法，为探索更加绿色、经济、高效、可持续的GVL合成途径，发展新的转化技术梳理思路并提供参考。

Abstract: So far, various platform molecules have been obtained from biomass and its derivatives. Among these molecules, γ-valerolactone (GVL) is widely used because of its high stability, low toxicity and low volatility. In this paper, various catalytic reaction systems such as H2 gas, formic acid (FA) or alcohols as hydrogen source for the hydrogenation of levulinic acid (LA) and its esters to GVL are summarized. The future research trends of the selective hydrogenation of LA to GVL are suggested.
