Abstract
The present invention relates to a process for preparing iodinated aromatic compounds. Particularly, the present invention comprises the step of performing the iodination of a non-halogenated aromatic compound, a monoiodo aromatic compound, a diiodo aromatic compound, and iodine in the presence of a zeolite catalyst under oxygen atmosphere. In the process for preparing iodinated aromatic compounds according to the present invention, an iodination and an iodine conversion simultaneously occur, and then prevent side-reactions. Also, the lifetime of an iodination catalyst used therein can be extended by controlling the reaction temperature stably. Therefore, the process can be used for mass production of diiodo compound.
