Abstract
The present invention relates to a method of preparing iodinated aromatic compounds, and more preferably a method of preparing iodinated aromatic compounds comprising a step of iodinating a react ant including an aromatic compound, a di-iodo aromatic compound or water, and iodine (I2) in the presence of a zeolite catalyst and oxygen. The method of the present invention has an advantage that by iodination of a reactant including the aromatic compound, and the di˜ iodo aromatic compound or water in the presence of the zeolite catalyst and oxygen, the temperature of the iodinating reactor can be controlled reliably and constantly, thereby resulting in improved productivity per unit weight of catalyst and inhibition of a side reaction in accordance with suppression of producing impurities. In addition, the productivity of the iodinated aromatic compound, preferably the di-iodo aromatic compound, more preferably a p-di-iodo aromatic compound can be improved, and thus can be widely used in the preparation of a di-iodo aromatic compound such as a p-di-iodo aromatic compound.
