Abstract
An improved integrated route to bis(2-pyridyl-1-oxide) disulfide is provided wherein a solution of 2-mercaptopyridine-1-oxide formed by oxidizing 2-chloropyridine with peracetic acid to form a reaction mixture of 2-chloropyridine-1-oxide which is then mercaptized, is reacted with in situ generated hypochlorous acid at a pH in the range of 4-8, the hypochlorous acid being generated by chlorinating the solution of 2-mercaptopyridine-1-oxide in the presence of a base selected from the group consisting of an alkali metal hydroxide, carbonate, bicarbonate or combinations thereof.
