Glass Ball as Bullet Solubility System: Nitromethane with Uranium bis(nitrato-O)dioxohexahydrate
Components:
   (1) Nitromethane; CH3NO2; [75-52-5]  NIST Chemistry WebBook for detail
   (2) Uranium bis(nitrato-O)dioxohexahydrate; UO2(NO3)2(6H2O); [13520-83-7]  NIST Chemistry WebBook for detail
Original Measurements:
   Warner, R.K., Austral. J. Appl. Sci. 4, 581-9 (1953).

 Variables:
   Temperature = 293 K

 Prepared By:
   V. P. Sazonov

 Experimental Remarks:
   The solubility of uranyl nitrate in nitromethane at 20.0 °C (293.2 K, compiler) was reported to be 100 w2 = 14.0. The corresponding mole fraction, x2, calculated by the compiler is 0.025.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   The analytical method was used. A sample of (2) was placed with the appropriate amount of pure solvent in a small flask. The contents of the flask were warmed to 30 to 50 °C, agitated with excess crystals for 15 min, and then placed in a constant temperature bath at 20 °C with intermittent shaking for 6 to 8 h. Crystallization of the supersaturated solution occurred, and when equilibrium was reached the solution was quickly decanted, filtered from the fine crystals, and placed in a stoppered flask at 20 °C for analysis.

 Source and Purity of Materials:
   (1) Synthesized by standard method; thoroughly dried and fractionally distilled.
   (2) Source not specified; A.R. grade; not purified.

 Estimated Errors:
   Solubility: ± 0.002 mass fraction.
   Temperature: ± 0.05 K.
