Part five is the conclusion . Preparation of Phosphorus Pentafluoride and the Solubility of Phosphorus Pentafluoride in Aether

五氟化磷的制备及其在乙醚中的溶解度

The result indicated that : the solubility of phosphorus pentafluoride in aether was decreasing as temperature rising ; when temperature rises from 0 ℃ to 30 ℃, the solubility of phosphorus pentafluoride in aether decrease from 1.5448g/mL to 0.7335g/mL .

通过实验发现，五氟化磷在乙醚中的溶解度随温度的升高而下降，当温度从0℃上升至30℃时，五氟化磷在乙醚中的溶解度从1.5448g/mL下降到0.7335g/mL。
