Excess Copper

The formation of N-carboxymethylaminoacetohydroxamic acid complexes in solutions with excess copper(II) or iron(III) ions or both of them was studied. In the presence of Cu(II), the binuclear complex Cu2H-1L+ was identified; in the ternary system, the complex CuFeH-1L+ was found. This complex formation is necessarily associated with the ligand structure >N-CH2.CO-NHOH and with a new property of hydroxamic acids of this type - detachment of two hydrogen ions from one carbohydroxamic functional group.

Diffusion Activation

The ?2 single phase interdiffusion in Ti3Al-Nb ternary system was studied at temperatures of 1323, 1373 and 1423 K. The interdiffusion coefficients were calculated by the method of Dayananda. The average ternary interdiffusion coeffcients were determined in the mid of the diffusion zone, and the trace diffusion coefficients can be estimitaed in the limit cX?0. The obtained main interdiffusion coeffcients is little smaller than privious reported and the diffusion activation energy of Nb calculated by the trace diffusion coefficients is 299.29 kJmol-1 accoding to the Arrhenius equation. These results can provide a theoretical basis for the mechanisms of Nb improving the oxidation resistance of Ti3Al.

SummaryThe measurement of the chemical reaction rates for complex formation as well as hydrolysis type reactions by the method of horizontal zone electrophoresis is outlined. The correlation between chemical equilibrium kinetics and electrodiffusion processes in a constant d.c. electric field is described. In model electromigration experiments the reaction rate constant of the formation a complex by Hf(IV) and diethylenetriaminepentaacetic acid (DTPA) is determined. The electrophoretic mobility, diffusion coefficient and stability constant of the [HfDTPA]
