Mutual solubility of nitromethane and water
t/°CT/K102 * Mass Fraction w1Mole Fraction x1 (compiler)Comment(s)
25.0298.210.00.032Water-rich phase
25.0298.298.00.935Nitromethane-rich phase
 Method/Apparatus/Procedure:
   Viscosity measurements were used to determine mutual solubilities of (1) and (2). Layers of each liquid were allowed to reach mutual saturation at 25 °C and the time of flow for each layer was measured. The upper layer, a saturated solution of (1) in (2) was diluted with water so that solutions containing known amounts of the saturated solution were obtained. The times of flow for these solutions were measured and compared with those for water containing weighed quantities of nitromethane. Similar measurements were made with the lower layer after dilution with nitromethane.
