The dissociations of five N-monosubstituted dithiocarbamic acids (I) in strongly acidic and alkaline solutions were investigated spectrophotometrically. The existence following equilibrium, _??_(eq. 6) was established. The values of dissociation constants were determined. The Brønsted correlations between pK'Ior pK'III and pKa of corresponding amines (pKN) were found; pK'I or pK'III 0.48 pKN+α(α=-9.06 for pK'I;eq. 7, and α=12.43 for pK'III;eq.8).
