Polymer complexes XXXII. Potentiometric and thermodynamic studies of cinnamaldehyde Anthranilic acid and its metal complexes in monomeric and Polymeric forms

摘要

Proton-monomeric ligand dissociation and metal-monomeric ligand stability constants of cinnamaldehyde anthranilic acid(CAA) with some transition metal ions were calculated potentiometrically in 0.1 MKCl and 50/100(v/v) ethanol-water mixture. Also, in the presence of 2,2'-azobisisobutyronitrile as initiator the proton-polymeric ligand dissociation and metal-polymeric ligand stability constants were calculated. The effect of temperature on the dissociation of CAA and the stability of its formed complexes were studied in monomeric and polymeric forms.
