170.5 g (1.08 mole) of sodium permangamate are added batchwise within a period of 30 minutes at 45° to 55° C. to a solution of 103.2 g (0.72 mole) of 4-propylthio-1,2,3-triazole in 320 ml acetic acid and 420 ml water. The solution is then stirred for 10 minutes at 45° C. and reacted at 20° C. with a solution of 159.8 g (0.84 mole) of sodium disulfite in 500 ml water up to complete decolorization. Thereupon extraction is effected four times with 250 ml of acetic acid ester. The organic phase is then dried on magnesium sulfate, filtered and concentrated in a vacuum.
