Method for preparing iodobenzene diacetate

The invention relates to a method for preparing iodobenzene diacetate, which comprises the following steps: using tetrahydrate sodium perborate as a raw material to perform acylation reaction with iodobenzene in the presence of a glacial acetic acid/acetic anhydride mixed solution, wherein the molar ratio of the tetrahydrate sodium perborate to the iodobenzene is 3-10:1, the reaction temperature is between 30 and 45 DEG C, and the reaction time is between 4 and 24 hours; after the reaction, adding ice water to obtain a crude product of the iodobenzene diacetate; and performing recrystallization to obtain the iodobenzene diacetate. Compared with the prior art, the method has the advantages of reasonable process, simple operation and safe production, is suitable for industrial mass production, and provides a favorable condition for producing the iodobenzene diacetate industrially.
