실험 절차

Tetrafluoroboric acid (250 ml, 2.00 mol) was added to cool (0° C.) pyridine (157.7 ml, 1.95 mol) within 25 min obtaining a colorless precipitate. After the acid was completely added the mixture was further stirred for 30 min at the same temperature. Then the reaction mixture was filtered. The residue was washed twice with cold ethanol and dried 12 h at high vacuum to yield 201.9 g (60%) pyridinium tetrafluoroborate as colorless crystals.
