Abstract
A series of 1,4-disubstituted aminoanthraquinones has been prepared from 1,4 ditosyloksyanthraquinone. The potentiometric and UV-spectrophotometric method have been used to study the acid-base properties of obtained compounds. The absorption spectra revealed the presence of vibroelectronic band in visible region for compounds containing two tertiary nitrogen groups. It indicates the separation of vibronic states in the molecule. Determined pKa values in acetonitrile used as a solvent indicate the influence of substitution of amino group on basicity of the anthraquinone moiety.
