HCID 27341761-Butylpyridinium Hexafluorophosphate

Procedure

Pyridine and excessive amount of chloro-n-butane (molar ratio: 1/1.05) were reacted at 70° C. with stirring for 48 hours. Excessive of reactants were removed by rotary evaporation, thereby N-butylpyridinium chloride was obtained. The obtained N-butylpyridinium chloride was further added into an aqueous solution with excessive amount of potassium hexafluorophosphate (molar ratio: 1/1.1) and stirred for 24 hours. After settlement, a product was separated from the reactant solution. After liquid separation, the product was washed with water until no chlorine ion was detected by a silver nitrate solution (0.1 mol/L). A product of N-butylpyridinium hexafluorophosphate was obtained after removing methylene dichloride in the product by rotary evaporation and drying.
