[Determination des constantes d'equilibre conditionnelles et des constantes de vitesse des reactions entre le selenium(IV) et cinq orthodiamines aromatiques].
The conditional equilibrium and rate constants, at various pH values, of the reaction between selenium(IV) and five aromatic orthodiamines, were determined. A main reaction of second order occurs first between the monoprotonated species of the diamine and the non-dissociated selenious acid. The hydrogen selenite ion and the diprotonated diamine can also react but more slowly. The reaction products are very stable.
