以葡萄糖为原料，通过碳材料的磺化反应，合成了一种新型的碳基强酸催化剂。采用水热碳化法取代传统的热处理方法制备新型酸催化剂，使碳化过程在更温和的条件下进行，收率更高。新型多相催化剂的酸性高达2.0 mmol/g，远高于Nafion和Amberlyst-15的0.8 mmol/g。通过缩醛化反应考察了催化剂的催化活性。结果表明，新型催化剂对该反应有很好的催化效果。新型碳基酸催化剂在绿色化工过程中具有巨大的应用潜力。
A novel carbon based strong acid catalyst has been synthesized through the sulfonation of the carbon materials from glucose. The novel acid catalyst was obtained through the hydrothermal carbonization instead of the traditional heat treatment, which made the carbonization process under much milder condition with higher yield. The novel heterogeneous catalyst owned the advantages of high acidity as much as 2.0 mmol/g, much higher than that of Nafion and Amberlyst-15 (0.8 mmol/g). The catalytic activities of the catalyst were investigated through the acetalization. The results showed that the novel catalyst was very efficient for the reaction. The novel carbon based acid catalyst holds great potential in the green chemical process.
