新平台化合物乙酰丙酸制备方法研究进展

Review on preparation methods of levulinic acid, a new platform chemical

综述了目前国内外以糠醇催化水解法和生物质直接水解法制备乙酰丙酸的研究进展 ,对这两种方法的优缺点进行了比较。目前我国乙酰丙酸制备存在着企业生产规模小、收率低、环境污染严重等问题。今后乙酰丙酸制备将以生物质资源直接水解法为主 ,通过对制备工艺的深入研究 ,向高效化。

Levulinic acid (LA) is an important chemical raw material whose applications will be wider and wider in various industries. LA is regarded recently as a promising new platform chemical from biomass. There are two methods to prepare LA: the catalyzed hydrolysis of furfuryl alcohol, and the hydrolysis of biomass. Their advantages and disadvantages are pointed out. Small-scale of production, low yield, and serious pollution are the major problems in producing LA in China. In the future, hydrolysis of biomass will turn to be the dominant method. With the deepgoing study of the preparation process engineering, hydrolysis of biomass will become more efficient and environment-friendly.
