Synthesis,Characterization And Properties Of The Polyamine-Co Oxygenated Complexes

Oxygen carriers are certain important transition metal complexes which can transport and store dioxygen reversibly in living bodies. The study on oxygen carriers is of important significance in military and civil applications, especially in the fields of dioxygen separation, metal anti-corrosion and keeping Suits fresh.Recently, solid-state reaction shows its great advantages in coordination chemistry. It breaks through rules of traditional liquid phase reaction and certain products can only be prepared by solid-state reactioa So introduction of solid-state reaction into the research of transition metal complexes of oxygen carriers would get a new break To establish this view, we have used solid-state reaction method to prepare some cobalt complexes as oxygen carriers, to study their oxygenation properties and to compare them with those obtained from classic liquid phase methods. The contents of this work contain six parts:1. Recent development of oxygenation of cobalt complexes was reviewed, such as the structure and properties of some typical oxygen carriers. Their significance as model of natural oxygen carriers and potential applications in industrial processes were discussed..2. A series of cobalt complexes were prepared from 1,3-diaminopropane , 1,4-diamino-butane, 3,3'-diaminodipropylamine with cobalt(II) chloride anhydrous, cobah(II) chloride hexahydrate via liquid-solid reaction , gas-solid reaction in room temperature and non-aqueous solution reactioa The influence of coordinated water to oxygenating properties of the complexes prepared by liquid-solid reaction was discussed.3. A series of cobalt complexes were prepared from the three amines mentioned above and cobalt (II) sulfate anhydrous, cobalt (II) sulfate heptahydrate by the threepreparing ways above. The influence of coordinated water to oxygenating properties of the complexes prepared by liquid-solid reaction was discussed4. Cobalt complexes were prepared from the three amines above and cobalt (II) acetate tetrahydrate by the three ways above. The result showed that complexes prepared by different amines have different oxygenating properties.5. Cobalt complexes were prepared from the three amines above and cobak (II) nitrate hexahydrate by the three ways above. The influence of anion to the ability of oxygen carriers was discussed.6. A new method of the preparation of 2,6-diformyl-4-methylphenol was presented Nanophase MnO2 was prepared and used in the synthesis of 2,6-diformyl-4-methylphenol.
