Versuchsvorschrift

To a 419.9 gm aliquot of the above solution of sodium pyridine-2-thiol-N-oxide (29.9 gm dry basis; 0.200 mole) was added a solution of zinc sulfate (20.0 gm, 52.5% concentration as hydrate; 0.111 mole) and water (80 gm) at room temperature. After 0.5 hour agitation, zinc pyridine-2-thiol-N-oxide was filtered and washed with water. The wet cake (60.2 gm) was dried to constant weight (33.8 gm; 0.107 mole or 100% yield; 97.1% assay). The zinc pyridine-2-thiol-N-oxide had the following color designation: L, 92.0; a, -3.5; b, 4.9. (Hunterlab Tristimulus Colorimeter, Model D25A-2, Reston, Va. 22090).
