Complexation study of dibenzo-18-crown-6 with UO22+ cation in binary mixed nonaqueous solutions

Abstract

The complexation reaction of macrocyclic ligand, dibenzo-18-crown-6 (DB18C6) with UO22+ cation Was studied in ethylacetate-1,2-dichloroethane (EtOAc/DCE), acetonitrile-1,2 dichloroethane (AN/DCE), methanol-1,2-dichloroethane (MeOH/DCE) and ethanol-1,2-dichloroethane (EtOH/DCE) binary solutions at different temperatures using the conductometric method. The conductance data show that thestoichiometry of the complex formed between DB18C6 and UO22+ cation is affected by the nature of the solvent systems. A non linearbehaviour
