A simple solid base catalyst, ammonium aluminum carbonate hydroxide (AACH), was prepared and its structure was characterized by many technologies, including XRD, FT-IR, SEM, BET and Elemental Analysis. The prepared catalyst was used to catalyze the conversion of glucose into 5-hydroxymethylfurfural (HMF) in ionic liquid 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) and dimethyl sulfoxide (DMSO) mixtures. Various reaction conditions, including catalyst loading, reaction temperature, reaction duration and solvent, were investigated. A moderated HMF yield of 52.17 % was obtained at the mild reaction conditions (120°C for 4 h). More importantly, the catalyst could be reused for several times without the loss of its significant catalytic activities. After five reaction runs, a HMF yield about 49.34 % was also obtained.
制备了一种简单的固体碱催化剂——碱式碳酸铝铵（AACH），并通过多种技术对其结构进行了表征，包括X射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）、比表面积测定（BET）和元素分析。将制备的催化剂用于催化葡萄糖在离子液体1-丁基-3-甲基咪唑氯盐（[Bmim]Cl）和二甲基亚砜（DMSO）混合物中转化为5-羟甲基糠醛（HMF）。研究了各种反应条件，包括催化剂用量、反应温度、反应时间和溶剂。在温和的反应条件（120℃，4小时）下，HMF的产率达到了52.17%。更重要的是，该催化剂可以重复使用多次而不会显著丧失其催化活性。经过五次反应后，仍可获得约49.34%的HMF产率。
