Participants

Reaction Steps

280 g (2.83 mols) of phosgene and 224 g (2.83 mols) of pyridine are metered synchronously into 1,600 g of methylene chloride at -10° C. in the course of 180 minutes. A fine-crystalline, pale yellow suspension results. After filtration with suction, with exclusion of moisture, 480 g (=95.5% of theory) of N-chlorocarbonyl-pyridinium chloride of decomposition point 60° C. are obtained.
