用途
使用
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.
製法・合成法
製造方法
Prepared by slowly adding PCl5 dropwise to an aqueous HF solution containing NaCl.
純化方法
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.]
