Abstract : The reaction of sodium in biphenyl, amylsodium, sodium benzophenone ketyl, and sodium naphthalene glycol ether with uranium tribromide is reported. Evidence is given that colloidal uranium is formed in certain instances but is too reactive to be isolated except in partially oxidized form. Reduction by organosodium reagents in the presence of hydrogen gas does not lead to uranium hydride in the reactions studied. Various observations on the reactivity of finely divided uranium and uranium tribromide with possible leaching agents are described. Uranium powder reacts with water, dilute base, isopropyl alcohol and, to some extent, with ether-methanol and acetone, but not with liquid ammonia. Uranium tribromide reacts with isopropyl alcohol and sodium isopropoxide forming isopropylates and with liquid ammonia probably to form the insoluble triamide. The density and x-ray diffraction pattern of uranium hydride as a function of hydrogen content have been measured, and a preliminary report is given indicating partial removal of H at low temperature does not greatly increase the density above that of UH3. A special drybox and certain anaerobic techniques are described together with a microscope hot-stage for observations in vacuum or under high gas pressures. jg p.4
