通过两种方法合成出Fe(Ⅳ)溶液,研究了Fe(Ⅳ)溶液的反应性、稳定性以及添加其他离子对Fe(Ⅳ)在水溶液中的稳定性的影响,并对Fe(Ⅵ)的反应历程进行了探讨。Fe(Ⅳ)离子的氧化性较Fe(Ⅵ)离子弱,可以氧化苯甲醇,而难以氧化间二甲苯;在Fe(Ⅳ)溶液中加入磷酸钠使其稳定性下降,而加入醋酸钠可显著提高Fe(Ⅳ)在溶液中的稳定性;Fe(Ⅳ)在溶液中的浓度越高越不稳定;随着碱浓度的增加Fe(Ⅳ)在溶液中的稳定性增强且在碱水溶液中Fe(Ⅳ)比Fe(Ⅵ)更稳定。
The Fe (Ⅳ) solution was synthesized by two methods. The reactivity and stability of Fe (Ⅳ) solution and the stability of Fe (Ⅳ) in aqueous solution by adding other ions were studied. The effects of Fe The reaction process is discussed. The oxidation of Fe (Ⅳ) ion is weaker than that of Fe (Ⅵ) ion, which can oxidize benzyl alcohol and make it difficult to oxidize m-xylene. The addition of sodium phosphate to Fe (Ⅳ) The stability of Fe (Ⅳ) in solution is improved. The higher the concentration of Fe (Ⅳ) in solution is, the more unstable it is. The stability of Fe (Ⅳ) increases with the increase of alkali concentration. (Ⅳ) is more stable than Fe (Ⅵ).
