Potentiometrie Studies on Stepwise Mixed Ligand Complex Formation
U ranium tetraethoxy monobenzoate (1.251 g.) was taken in benzene (55 g .). To this tertiary butanol (0.65 g.) was added. The reaction m ixture was refluxed for seven hours. D uring this period benzene ethanol azeotrope was collected slowly. Followed by a few ml of pure benzene at 80 °C. On drying under reduced pressure as above a reddish brown viscous liquid (1.47 g.) sparingly soluble in benz...
متن کاملA Polarographic Study of Uranyl-Salicylate and Uranyl-Phthalate Complex Formation in Acidie Solutions
The d. c. and a. c. polarography and cyclic voltammetry were applied to the study of uranyl-salicylate and uranyl-phthalate complexes. The study was limited to the pH range <5, because insoluble uranyl-hydroxydes are formed above this pH value. Uranyl-salicylate and -phthalate are irreversibly reduced. The electrode process is preceded by the chemical reaction of the complex with protons. By th...
متن کاملIsolation of a uranyl amide by "ate" complex formation.
The uranyl amide [{Li(DME)}(2)Cl][Li(DME)][UO(2)(NC(5)H(10))(3)](2) has been synthesised and structurally characterised. Its stability is attributed to the saturation of the uranyl coordination sphere by "ate" complex formation.
متن کاملUranyl peroxide enhanced nuclear fuel corrosion in seawater.
The Fukushima-Daiichi nuclear accident brought together compromised irradiated fuel and large amounts of seawater in a high radiation field. Based on newly acquired thermochemical data for a series of uranyl peroxide compounds containing charge-balancing alkali cations, here we show that nanoscale cage clusters containing as many as 60 uranyl ions, bonded through peroxide and hydroxide bridges,...
متن کاملStudies on Nickel(II)-Pyridoxamine-Imidazole Containing Mixed Ligand Complex Systems
The stability constants of species present in the systems Ni(II)-pyridoxamine(pym)(A) and Ni(II)-pyridoxamine(pym)(A)-imidazole containing ligands(B) [B = imidazole(him), benzimidazole(bim), histamine(hist) and L-histidine(his)] have been determined pH-metrically using the MINIQUAD computer program. The existence of the species NiAH, NiA and NiA2 was proven for the Ni(II)-pym(A)...
