Abstract
Complex formation was studied in the systems boric acid (sodium monoborate)-polyol (D-sorbitol, mannitol, dulcitol, xylitol, glycerol)-water, concentrational stability constants of the complexes and ionization constants of bis(polyol)boric acids were estimated. In the systems D-sorbitol, D-mannitol, dulcitol, glycerol-boric acid-water electric conductivity increases sharply to peak at the molar ratio polyol : boric acid = 2 : 1; in the case of dulcitol there appears yet another peak at the molar ratio polyol : boric acid = 1 : 1. In the systems D-sorbitol, D-mannitol, glycerol-sodium monoborate-water three complex anions: [BPolyol2]− in acidic, [BPolyol]−, and [B2Poyol]2- in neutral and basic regions of the system were revealed, their stability being dependent on the nature of the polyol and the overall concentration of the solution. In the system dulcitol-sodium monoborate-water only one complex anion [BDulc]− is formed, and in the system xylitol-sodium monoborate-water dimeric complex [BXyl]− is found.
