Dioximes of large ring 1,2-diketones and their applications to the determination of bismuth, nickel and palladium

Abstract

The preparation of alicyclic vic-dioximes containing 5 to 12 carbon atom rings from the corresponding 1,2-diketones is reported, and their application to the gravimetric determination of bismuth in the presence of several complexing agents is described. The dependence of complete precipitation of bismuth upon pH, and the effect of foreign ions has been studied. A polymeric structure is suggested for the bismuth-dioxime compounds. The application of large ring (8 to 12 carbon atoms)vic-dioximes to the gravimetric determination of nickel and palladium has been studied; the infrared and ultraviolet spectra of the nickel(II) and palladium(II) complexes are presented.
