    • The present invention relates to a method for preparing polyarylene sulfide, in which the polyarylene sulfide is prepared by a polymerization reaction of reactants including a diiodo aromatic compound and a sulfur compound, the method including: further adding 0.01 to 10.0 wt. % of diphenyl disulfide with respect to the weight of the polyarylene sulfide to the reactants to form the polyarylene sulfide having a melting point of 265 to 320° C.The diphenyl disulfide included in the reactants according to the present invention costs far less than other conventional polymerization inhibitors to dramatically lower the production cost, and the polyarylene sulfide prepared using the diphenyl disulfide exhibits low iodine content and very excellence in thermal stability.

    • 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. 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.
    • 本发明涉及一种制备碘化芳族化合物的方法,更优选的是制备碘化芳族化合物的方法,其包括将包含芳族化合物,二碘芳族化合物或水的反应物和碘(I 2)碘化的步骤 存在沸石催化剂和氧气。 本发明的方法具有的优点是,通过在沸石催化剂和氧气的存在下,通过碘化包含芳族化合物和二碘芳族化合物或水的反应物,可以可靠地控制碘化反应器的温度, 从而导致每单位重量催化剂的生产率提高,并且抑制副产物产生杂质。 此外,可以提高碘化芳香族化合物,优选二碘芳香族化合物,更优选对二碘芳香族化合物的生产率,因此可以广泛用于制备二碘芳族化合物,例如 作为对二碘芳族化合物。
