摘要：

Schiff bases of acetylacetone, benzoylacetone, dibenzoylmethane, and thienoyltrifluoroacetone with ethanolamine and 2-aminophenol were synthesized and characterized by elemental analysis, infrared and H-1 NMR spectra. Dissociation constants of the synthesized ligands were determined in methanol-water and at an ionic strength of 0.1 M KNO3 at different temperatures; the associated thermodynamic parameters were calculated. Single crystals of one of the ligands were prepared; the X-ray diffraction pattern was analyzed. Thermal analyses of the investigated ligands were performed and correlated with the ligand structure.
