摘要
The present invention relates to a process for the preparation of zinc 2-mercaptopyridine-N-oxide in a readily filterable, washable and easily suspendable form which comprises reacting an aqueous solution of an alkali metal salt of 2-mercaptopyridine-N-oxide with an aqueous solution of a water soluble zinc salt at a temperature of 35 DEG to 100 DEG C. in the presence of an at least partially water soluble organic solvent to form a precipitate of zinc 2-mercaptopyridine-N-oxide, recovering the said crystals and optionally comminuting the crystals.
