UCl 3 melts at 837 °C and boils at 1657 °C. Uranium(III) chloride has a density of 5500 kg/m 3 or 5.500 g/cm 3. Its composition by weight: Chlorine: 30.84% Uranium: 69.16%. Its formal oxidative states: Chlorine: −1 Uranium: +3. This salt is very soluble in water and is also very hygroscopic. UCl 3 is more stable in a solution of ...
4 UO 3 + 10 CCl 4 → 4 UCl 5 + 10 COCl 2 + O 2 It can also be prepared from the reaction between uranium tetrachloride and chlorine in a fluidized bed reactor at 550 °C. [ 1 ]
UCl 4 + x ROH ⇌ UCl 4−x (OR) x + x HCl. Uranium tetrachloride dissolves in non-protic solvents such as tetrahydrofuran, acetonitrile, dimethyl formamide etc. that can act as Lewis bases. Solvates of formula UCl 4 L x are formed which may be isolated. The solvent must be completely free of dissolved water, or hydrolysis will occur, with the ...
