  N-Substituted 2-aminoethylidenediphosphonic acids as complexones

  摘要：

  A novel complexone, 2-dimethylaminoethylidenediphosphonic acid, was synthesized. Its acid-base and complexation properties were studied by potentiometric titration in aqueous solutions (25 degrees C) and compared to those of 2-amino-1-hydroxyethylidencdiphosphonic acid and omega-aminoalkylidenediphosphonic analogs. Parameters of efficiency and selectivity of complexation were determined. The influence of the alkylidene chain length on complexone properties in a series of omega-aminonlkylidcnediphosphonic acids was analyzed.
