微波辐射下氯化锌催化纤维素转化为呋喃类物质的研究
Conversion of cellulose to furans catalyzed by zinc chloride under microwave irradiation
摘要
Abstract
Cellulose was degraded in concentrated ZnCl2 solution which acted as a solvent and catalyst under microwave irradiation. Cellulose was directly converted into two main furans, 5-hydroxymethyl furfural (5-HMF) and l-(furan-2-yl)-2-hydroxyethanone. Factors affecting the mol yields of these two compounds were investigated at different temperatures, reaction times, concentrations of ZnCl2, cellulose contents, and microwave powers. For 1 g cellulose reacted with 140 tnL 69% ZnCl2 solution, the mol yields of 5-HMF reached to 19.4% under the microwave power of 500 W and l-( furan-2-yl) -2-hydroxyethanone reached to 12.0% under the microwave power of 600 W at 135 ℃ within 5 min.关键词
