摘要:
The present invention generally relates to a novel process for preparing alkali metal pyrithione from pyridine N-oxide, using a sulfurination agent and a base agent. In particular, the present invention relates to an efficient process for preparing polyvalent metal complexes of sodium pyrithione from the alkali metal pyridine N-oxide described herein.
