Uranyl perchlorate

Crystals of uranyl perchlorate, U02(C10[13093-00-0] have been obtained with six and seven hydration water molecules. The uranyl ion is coordinated with five water molecules (4) in the equatorial plane with a U—O(aquo) distance of 245 nm (2.45 E). The perchlorate anion does not complex the uranyl center. The unit cells contain two [0104] and one or two molecules of hydration water held together by hydrogen bonding (164). [Pg.326]

Uranyl Perchlorate, UOjlCIO lj.hHgO, is prepared by adding perchloric acid to a solution of potassium uranate, filtering off the precipitated potassium perchlorate, and evaporating the filtrate over phosphorus pentoxide. It forms yellow prismatic ciy stals, which melt at 90° C, and at 100° C. lose water, yielding the tetrahydrate, V0, C10,) AB. 0. [Pg.298]

The Schiff-base condensation of dap and 1,2-diaminobenzene in the presence of a stoichiometric quantity of uranyl perchlorate produced a mixture of U02(L663)(C104)2 and L665, from which the organic side product was removed by repeated extraction with boiling tetrachloroethylene [43]. [Pg.216]

In trlbutyl phosphate, the dissociation of uranyl nitrate Increases as Its concentration In the organic phase Is decreased. At 10 M the salt Is approximately 0 per cent dissociated,l.e., Aii/120 0.4. Uranyl perchlorate at this concentration Is almost completely Ionized.Ion association occurs at higher concentrations, but significantly less than for uranyl nitrate. At approximately O.OIM, the association of uranyl perchlorate Is maximum (At)/120 has a minimum value of 0.l) In the concentration range lO" to IM. The Ionization of this salt may well be associated with the... [Pg.32]

Prom figure 2, it can be seen that uranyl nitrate la extracted more efficiently by the various solvents than la uranyl perchlorate. Better separation of uranium and thorium is also achieved from nitrate solution rather than perchlorate. [Pg.105]
