A study of the physico-chemical properties of 1, 3, 5-trihydroxy-1, 3, 5-triazin-2, 4, 6(1H, 3H, 5H)-trione

Acetyl (Ia) and pivaloyl (Ib) triesters of the 1N, 3N, 5N-trihydroxy-1, 3, 5-triazin-2, 4, 6[1H, 3H, 5H]-trione (I) were synthesised. The spectrophotometric and potentiometric investigation of I revealed a weak acidic properties of triprotonic acid (pKa1 = 5.23, pKa2 = 6.32, and pKa3 = 7.93). The MS and TGA analyses of I indicated on hydroxyisocyanate as possible degradation product. The chelating ability of I with Fe(III)-ion was preliminary explored. IR measurements of aqueous solutions of I in the presence of Fe(III) ion showed the possible chelating ability of all hydroxamic moieties. The chemical structures and properties of investigated compounds were derived from the results of IR, 1H and 13C NMR, UV and MS spectrometric data, as well as thermogravimetric and potentiometric analysis.
