Hydrazinecarboximidamide, sulfate (1:?) Use and Manufacturing

Methods of Manufacturing

(1) It is obtained by the action of hydrazine sulfate with lime nitrogen, and then neutralizing with sulfuric acid to form a salt: first suspend hydrazine sulfate in water, gradually add lime nitrogen under cooling and stirring, control the temperature at about 20°C, react for 8 hours, then Filter, wash the filter cake with water, and drain; combine the filtrate and washing liquid, neutralize with 50% sulfuric acid at room temperature to pH=5, filter to remove calcium sulfate, concentrate the mother liquor under reduced pressure, cool, and precipitate white crystals, then pass it on ice After washing with water and draining, the yield is about 72%. (2) Obtained from the reaction of methyl isothiourea sulfate and hydrazine hydrate: dilute 119ml of 42% hydrazine hydrate solution with an equal volume of water, and then add it to 139g of methyl isothiourea sulfate in 200ml of aqueous solution, temperature It is 10°C. The methyl mercaptan released by the reaction is absorbed in the sodium hydroxide solution. After the reaction solution was concentrated to 200ml, an equal volume of 95% ethanol was added to precipitate aminoguanidine sulfate, and the crystals were filtered out. Concentration of mother liquor can also obtain partial crystals. The crystals are dried under vacuum to obtain the finished product. The yield is 90%.

Uses

Organic synthesis, pharmaceutical intermediates.
