综述了介孔材料合成芳酮的催化效果及应用进展。着重介绍了几种具有代表性的介孔材料MCM-41、SBA-15、HMS及其改性对芳酮的收率和选择性的影响。芳烃主要有苯环、萘环、杂环化合物,酰化试剂为羧酸、酸酐和酰氯。简述了催化剂失活的原因,结果表明,不同结构的介孔材料对不同的酰化反应具有不同的催化活性。

Advances of application of mesoporous materials in synthesis of aromatic ketones are reviewed in this dissertation. Several kinds of mesoporous materials, such as MCM-41, SBA-15, HMS and their modification are specially introduced, and the yield and selectivity of aromatic ketones are studied. The synthesis of aromatic ketones containing benzene ring, naphthalene ring and aromatic heterocycle in the presence of mesoporous materials catalysts has been discussed. Different acylating agents such as acid chlorides, anhydrides and carboxylic acids are used. Meanwhile, the reasons of deactivation and regeneration of the catalysts are listed. It is demonstrated that different mesoporous materials catalyzed different acylation reactions.
