Abstract
A novel complexone, 2-dimethylaminoethylidenediphosphonic acid, was sy nthesized. Its acid-base and complexation properties were studied by p otentiometric titration in aqueous solutions (25 degrees C) and compar ed to those of 2-amino-1-hydroxyethylidencdiphosphonic acid and omega- aminoalkylidenediphosphonic analogs. Parameters of efficiency and sele ctivity of complexation were determined. The influence of the alkylide ne chain length on complexone properties in a series of omega-aminonlk ylidcnediphosphonic acids was analyzed.
