摘要
以木质纤维原料非均相催化转化制备高附加值平台化合物乙酰丙酸和乙酰丙酸酯为研究对象,对以硫酸盐为催化体系的木质纤维定向转化生成乙酰丙酸和乙酰丙酸酯的国内外的研究进展和趋势进行了综述。文章概述了乙酰丙酸及乙酰丙酸酯在工业产业中的应用情况;重点比较了不同硫酸盐催化木质纤维制备乙酰丙酸及乙酰丙酸酯的过程,并对不同溶剂体系协同作用下的木质纤维转化为乙酰丙酸和乙酰丙酸酯过程的影响规律进行了深入分析,总结了硫酸盐类催化剂催化木质纤维定向转化的过程机理。同时针对现有工艺存在的问题进行了分析,展望了该研究领域的发展方向。
In this paper,the heterogeneous catalytic conversions of lignocellulose to high value-added platform compounds of levulinic acid and esters were studied.The research progress and trend of the direct conversion of lignocellulose to levulinic acid and esters using sulfate as catalytic system at home and abroad were reviewed.Firstly,the basic information of levulinic acid/esters and their application in industrial production were summarized.The preparation process of levulinic acid/esters using different sulfate catalysts was compared,and the law of the conversion of lignocellulose to levulinic acid/esters under the synergy effects of different solvent systems was deeply analyzed.And,the mechanism of direct conversion of lignocellulose catalyzed by sulfate catalysts was also summarized.Finally,the problems of existing process were discussed,and the development direction of this research field was prospected.
