White solid, sensitive to air and carbon dioxide, highly soluble in water, decomposes at high temperatures.??
Sodium hexafluorophosphate is used as an ion pairing agent for the determination of cobalt(II) in water samples. It is used as an important raw material in the preparation of 2-chloro-1,3-bis(dimethylamino)trimethinium hexafluorophosphate.?? ??
Prepared by slowly adding PCl5 dropwise to an aqueous HF solution containing NaCl.Purification Methods
Recrystallise it from acetonitrile and dry it in a vacuum for 2days at room temperature. It is an irritant and is hygroscopic. [Delville et al. J Am Chem Soc 109 7293 1987.]??? ????????? ?? ?? ? ???
