실험 절차

Tetrafluoroboric acid (250 ml, 2.00 mol) was added to cool (0° C.) pyridine (157.7 ml, 1.95 mol) and within 25 min a colorless precipitate was obtained. 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%) pyridiniumtetrafluoroborate as colorless crystals.
