Application of mesoporous molecular sieve-based solid acid-base catalyst in synthesis of transformer insulating oil

The invention belongs to the technical field of preparation of insulating oil, and particularly relates to application of a mesoporous molecular sieve-based solid acid-base catalyst in synthesis of transformer insulating oil. The mesoporous molecular sieve-based solid acid-base catalyst is used for synthesizing transformer insulating oil through cottonseed oil ester exchange, and the preparation method of the mesoporous molecular sieve-based solid acid-base catalyst comprises the following steps: synthesis of a hard template, preparation of a catalyst skeleton, preparation of a precursor and preparation of the solid acid-base catalyst. The mesoporous molecular sieve-based solid acid-base catalyst synthesized by the method has the advantages of high activity, long performance retention life, no requirement on the acid value of raw materials and the like, and can be used for producing transformer insulating oil by ester exchange of cottonseed oil. 本发明属于绝缘油制备技术领域，具体涉及一种介孔分子筛基固体酸碱催化剂在变压器绝缘油合成中的应用。介孔分子筛基固体酸碱催化剂用于棉
