| 摘 要： | 将纤维素溶解在ZnCl_2溶液中,以SnCl_4为催化剂,微波下使纤维素降解成5-羟甲基糠醛(5-HMF)。实验考察了微波功率、纤维素的质量、ZnCl_2溶液浓度、反应时间及催化剂与纤维素物质的量比等对5-HMF产率的影响。结果表明,以SnCl_4为催化剂,在优化条件:1.0 g纤维素溶解在100 m L 70%ZnCl_2溶液中,微波功率为420 W,降解反应9 min,SnCl_4与纤维素物质的量比2∶1下,5-HMF的产率达到39.4%。

| Abstract: | Conversion of cellulose into 5-hydroxymethylfurfural (5-HMF) catalyzed by SnCl4 in ZnCl2 solution with microwave was studied. The effects of microwave power, cellulose content, concentration of ZnCl2, reaction time and the molar ratio of SnCl4 to cellulose on the yields of 5-HMF were investigated. The results showed that under the optimum reaction condition of 1.0 g cellulose dissolved in 100 mL 70% ZnCl2 solution, the molar ratio of SnCl4 to cellulose of 2:1, the microwave power of 420 W, and the reaction time of 9 min, the yield of 5-HMF reaches 39.4%. |
