Versuchsvorschrift

Methyl dithiocarbazinate (24.4 gm., 0.2 mole) was dissolved in 200 ml. of absolute ethanol and 18 ml. (0.3 mole of hydrazine) of 85% hydrazine hydrate was added. The resulting solution was refluxed until no more solid thiocarbohydrazide precipitated (about 45 minutes). A small amount of 3-hydrazino-4-amino-5-mercapto-1,2,4-triazole that had formed was removed as follows. The reaction mixture was chilled, and the resulting solid product was collected and recrystallized from water acidified with a few drops of hydrochloric acid.
