Artykuł
Acid–base equilibria in selected o-methylamino-N-dialkylphenols in aqueous solutions are discussed. Analysis of the pH dependence of the UV absorption spectra with application of the multi-channel least-squares procedure allows the estimation of some microscopic dissociation constants. Results are discussed on the basis of intramolecular interactions between different substituents in phenol rings and protonation of the methylamino groups in amino acids.
