研究了微晶纤维素在Bimodal-HZ-5沸石上水解直接合成5-羟甲基糠醛（5-HMF）的工艺。对H-ZSM-5进行脱硅改性后得到的双峰型hz -5沸石是一种潜在的多相催化剂，纤维素转化率为67%，5-HMF收率为46%。双峰- hz -5被观察到可重复使用四个周期，没有任何活性损失。并对工艺参数的优化和催化剂的可重用性进行了详细的介绍。本研究为一锅法再生合成5-羟甲基糠醛开辟了一条新途径。
Direct synthesis of 5-hydroxymethylfurfural (5-HMF), a useful renewable biofuel and biochemical, was systematically studied by hydrolysis of microcrystalline cellulose over Bimodal-HZ-5 zeolite. Bimodal-HZ-5 zeolite obtained by post-synthesis modification of H-ZSM-5 with desilication was found to be a potential heterogeneous catalyst with 67% cellulose conversion and 46% yield of 5-HMF. Bimodal-HZ-5 was observed to be reusable for four cycles, without any loss in activity. The detailed optimization of process parameters and catalyst reusability are also presented. The present study opens a new avenue for the renewable one-pot synthesis of 5-HMF, a valuable product.
