Procedure

To a 514.8 gm aliquot of the above solution of sodium pyridine-2-thiol-N-oxide (30.9 gm dry basis; 0.207 mole) was added a solution of zinc sulfate (20.3 gm; 52.5% concentration as hydrate; 0.113 mole), and water (81 gm) at room temperature. After 0.5 hour agitation, insoluble zinc pyridine-2-thiol-N-oxide was filtered and washed with water. The wet cake (59.9 gm) was dried to constant weight (33.8 gm; 0.107 mole or 85.2% yield; 96.1% assay). The zinc pyridine-2-thiol-N-oxide had the following color designation: L, 93.0; a, -3.7; b, 5.2. (Hunterlab Tristimulus Colorimeter, Model D25A-2, Reston, Va. 22090).
