乙酰丙酸制备工艺的研究现状

Research Status of Preparation Technology of Levulinic Acid

从原料来源、催化机理、研究进展3个方面分析了酸催化水解生物质制备乙酰丙酸的研究现状,介绍了糠醇、以单糖和蔗糖为代表的糖类物质和以淀粉和纤维素为代表的生物质制取乙酰丙酸的方法,分析了糠醇、糖类物质和生物质制取乙酰丙酸的机理,以期为开展乙酰丙酸的研究提供参考。

This paper discussed the current research status of acid-catalyzed hydrolysis of biomass-derived levulinic acid(LA)with 3 aspects i.e.sources of raw materials,catalytic mechanism and research progress.The method of preparing levulinic acid from furfuryl alcohol,carbohydrate represented by monosaccharide and sucrose,biomass represented by starch and cellulose were introduced.Meanwhile,the mechanism of preparing LA was analyzed,which provided reference for the study of levulinic acid.
