Preparation method and application of catalyst for preparing aldehyde by oxidation method

The invention relates to a preparation method and application of a catalyst for preparing aldehyde through an oxidation method, the catalyst is prepared through a coprecipitation method, trimethylolethane and a high-molecular polymer polyphenyl diamide are added in the preparation process for modification, the structure of the catalyst is improved, the binding force between components is enhanced, and therefore the stability and selectivity of the catalyst are improved. The catalyst prepared by the method can be applied to industrial devices for preparing aldehyde through alcohol oxidation, such as preparation of formaldehyde through methanol oxidation. 本发明涉及一种氧化法制备醛的催化剂的制备方法及其应用，该催化剂采用共沉淀法制备，制备过程中添加三羟甲基乙烷和高分子聚合物聚苯二酰胺进行改性，改善催化剂结构，增强组分之间的结合力，从而提高催化剂的稳定性和选择性。该方法制备的催化剂可应用于醇氧化制备醛的工业装置上，例如甲醇氧化制备甲醛等。
