| titleOfInvention | A kind of intermediate of hindered phenol antioxidant and preparation method thereof |
| abstract | The invention relates to the technical field of synthesis of hindered phenol antioxidants, in particular to a method for preparing an intermediate of hindered phenol antioxidants. The preparation steps are as follows: in the presence of a catalyst, the hindered phenol antioxidant The intermediate of the oxygen agent; the intermediate of the hindered phenol antioxidant disclosed in the present invention, the modifiability of N on the hindered amine ring and the replaceability of the ester group greatly enrich the types of hindered phenol antioxidant, and it is a new type of high-efficiency It can provide new ideas for the design and preparation of phenolic antioxidants; in addition, the reaction provided by the invention is simpler than conventional reaction processes, has less environmental pollution, wide and cheap raw material sources, and high final yield of products, making it more economically valuable. |
