Abstract

In a process for the preparation of bis-2-pyridyl-disulfide or bis-(2-pyridyl-1-oxide)-disulfide optionally substituted on the pyridyl ring with at least one substituent selected from the group consisting of halogen and alkyl and alkoxy of 1 to 4 carbon atoms by oxidation of the corresponding 2-mercapto-pyridine or its N-oxide, the improvement comprising effecting the oxidation in an aqueous acid media containing an alkali metal or alkaline earth metal chlorite.
