DISPROPORTIONATION OF AG(I) IONS IN THE PRESENCE OF SATURATED TETRAAZACYCLIC AMINES IN PROPYLENE CARBONATE

The formation constant of the complex of Ag(I) with 8,11-tetramethyl-1 ,4,8,11-tetraazacyclotetradecane (TMTACT), log beta = 14.20, and the e quilibrium constants of Ag(I) ions disproportionation in the presence of TMTACT - log K(d) = 17.04, 1,4,8,11-tetraazacyclotetradecane (TACT) - log K(d) = 19.41, and 1,4,8,12-tetraazacyclopentadecane (TACP) - lo g K(d) = 20.09, in propylene carbonate were determined by potentiometr y. Complexes of Ag(II) with these amines were separated and characteri zed by spectrophotometry. The mechanism of the electrode processes tak ing place in propylene carbonate solutions of the Ag(II) complexes wer e determined by voltammetric methods and the resultant redox systems w ere identified.
