ABSTRACT:
Pyridine is reacted with chlorine at a molar ratio of pyridine to chlorine of 0.5-10 : 1 in a gaseous phase in the presence of at least 0.2 moles, preferably 1 to 20 moles of steam per mole of pyridine under irradiation of ultraviolet rays of 2000-5000 A, thereby producing 2-chloropyridine.
