Isomerization of glucose, galactose and arabinose to corresponding keto-sugars was studied in the present work over a range of heterogeneous catalysts. Magnesium aluminates with different ratios between oxides resulting in materials with a Mg/Al ratio from 0.2 to 0.9 were prepared, characterized and evaluated in terms of their catalytic behavior. The catalyst with a Mg/Al ratio close to hydrotalcites was the most efficient considering activity, selectivity and stability. The sugar structure was shown to have a minor influence on catalytic activity and selectivity.

醛糖到酮糖的相互转化：非均相催化剂上的半乳糖和阿拉伯糖异构化

在当前的工作中，研究了葡萄糖，半乳糖和阿拉伯糖向相应的酮糖的异构化，该异构化是在多种非均相催化剂上进行的。制备了氧化物之间具有不同比例的铝酸镁，从而得到Mg / Al比为0.2至0.9的材料，并对其催化性能进行了表征和评估。考虑到活性，选择性和稳定性，Mg / Al比接近水滑石的催化剂是最有效的。已显示糖结构对催化活性和选择性影响很小。
