Carbon Dioxide → Aminoguanidine Hemisulfate

Participants

Reaction Steps

Aminoguanidinium bicarbonate (27.2 g of 98.5%, 0.2 mole) was slurried in 150 ml of water. Sulfuric acid (10.2 g of 96%, 0.1 mole) was added over 1/4 hour with the evolution of carbon dioxide. After post-reacting one hour at room temperature, 125 ml of water were vacuum stripped. On cooling a white precipitate formed which was filtered and dried. Obtained were 11 g of product.
