Abstract: Levulinate esters have been recognized as an important platform chemicals and have a wide range of applications. This article summarizes the route of biore?nery，and then presents the up-to-date development of biorefinery in technologies and applications. Three routes of levulinate esters production are introduced，which include the route of synthesis reaction from levulinic acid，the route of conversion from furfuryl alcohol and the route of cellulosic biomass alcoholysis；and the advantages and disadvantages were also compared. Finally，for further application，the direct alcoholysis of biomass to produce levulinate esters will be the future trend. It is necessary to obtain the thermodynamic properties and other data during the reaction of direct alcoholysis of biomass and to strengthen the research with the related subjects，so as to build the theory foundation of the direct alcoholysis of biomass to produce levulinate esters.

Key words: levulinate esters, biorefinery, alcoholysis, levuniate acid, levulinate esters, biore?nery, alcoholysis, levuniate acid

摘要： 乙酰丙酸酯类是比较重要的一类平台化合物，具有广泛的应用。本文首先介绍了乙酰丙酸酯类的生物炼制途径，然后综述了目前国内外制备乙酰丙酸酯类的研究现状和最新进展。乙酰丙酸酯类的主要制备方法包括乙酰丙酸合成法、糠醇转化法以及生物质醇解法，并对3种方法的优劣进行说明，指出今后乙酰丙酸酯类的制备方法将以生物质直接醇解法为主。建议着力建立生物质直接醇解法反应过程中的热力学性质等相关数据，并加强与此相关的交叉学科的研究，以构建生物质醇解法制备乙酰丙酸酯类的理论基础。
