摘要
糠醛是一种含杂环有机化合物重要的化工产品。以蔗糖为原料微波加热回流制备5-羟甲基糠醛,探索在不同条件下对合成5-羟甲基糠醛的影响,得到最佳反应条件,硫酸为催化调节PH值1-2,微波功率为300W,在水溶液中搅拌回流40-50s,产率达90%。
This synthesis focuses on preparing 5-hydroxymethylfurfural(HMF) from sucrose in water(pH1-2) with Mcro-wave,studying the conditions which influence the productivity of the pointed compounds,and working out the best conditions.
