Versuchsvorschrift
103 ml of 1,4-butanesultone was added to 378 g of hydrazine hydride (80%) dropwise slowly, and stirred for 30 minutes at room temperature and for further 1 hour at 70° C. Water and hydrazine hydride were removed to obtain white crystals. These crystals were dispersed in 1.5 liters of methanol, and then refluxed for 1 hour and allowed to stand at room temperature. The crystals were collected, twice washed with 100 ml of methanol, and dried to obtain 115 g of 4-sulfobutylhydrazine. (m.p.: 152°-154° C.)
