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 reactant 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.
