以廉价的甘蔗渣和微晶纤维素为原料，通过不完全碳化和磺化反应制备固体酸催化剂。以微晶纤维素（C-SO 3 H）为原料合成的固体酸比以甘蔗渣为原料合成的固体酸具有更好的催化性能。采用多种技术对C-SO 3 H进行表征，研究葡萄糖和果糖催化转化为5-羟甲基糠醛（5-HMF）的反应条件。葡萄糖的转化率为73.29 ± 0.74%，果糖的转化率达到最大值98.85 ± 0.01%。5-HMF的选择性和产率分别达到65.04 ± 0.28%和64.29 ± 0.27%的最大值。使用C-SO 3 H作为催化剂，葡萄糖的转化在不同温度下遵循二级动力学，而果糖的转化遵循一级动力学。葡萄糖和果糖转化的活化能分别为73.75和51.87 kJ · mol-1。
Low‐cost bagasse and microcrystalline cellulose were used as the raw materials to prepare solid acid catalysts via incomplete carbonization and sulphonation. The solid acid synthesized from microcrystalline cellulose (C‐SO3H) exhibited better catalytic performance than that synthesized from bagasse. C‐SO3H was characterized by various techniques to study the reaction conditions of the catalytic transformation from glucose and fructose to 5‐hydroxymethylfurfural (5‐HMF). The conversion of glucose was 73.29 ± 0.74 %, and the conversion of fructose reached a maximum of 98.85 ± 0.01 %. The selectivity and yield of 5‐HMF reached maxima of 65.04 ± 0.28 % and 64.29 ± 0.27 %, respectively. Using C‐SO3H as the catalyst, the conversion of glucose followed second‐order kinetics at various temperatures, while the conversion of fructose followed first‐order kinetics. The activation energies of the glucose and fructose transformations were 73.75 and 51.87 kJ · mol−1, respectively.
