Distribution and dimerization of some μ-imidodiphosphates

Abstract

The distribution of chelate-forming reagents on a basis of arylimidodiphosphate between different organic solvents and 0.1 mol L -1 HNO 3 has been studied by liquid-liquid extraction of 46 Sc. The values of dimerization constants K 2 in selected solvents, particularly on the chlorine and chlorine-fluorine hydrocarbon basis as well as distribution constants K D (HA) have been determined.
