英文摘要:

      The work aims to collate and analyze the preparation of aldehyde compounds with various types of solid acids, so as to provide a reference basis for their green synthesis processes and extensive applications in the field of packaging materials. The types of solid acids used in the catalytic synthesis of aldehyde compounds were sorted out and the synthesis mechanisms and pros and cons of different catalysts were analyzed comparatively, including supported heteropoly acids, metal oxides, SO42−/MxOy super-strong solid acids, and supported ionic liquids. The recent trends in the research and development of aldehyde compounds in the field of packaging materials in China and abroad were summarized. Loss of relevant literature confirms the feasibility of using aldehyde compounds to prepare packaging materials, and the method of synthesizing aldehydes using solid acids aligns with the principles of green and sustainable development. This opens up new pathways for the green and controllable preparation process of aldehydes, thereby significantly advancing the large-scale application of aldehyde derivative products in packaging materials.
