2020 High quality Aminoguanidine Hemisulfate Salt – aminoguanidinium sulphat – Hailun New Material Detail:

Product Name: aminoguanidinium sulphat
Molecular Formula:C2H14N8SO4
CAS: 966-19-0
Melting Point:206 degrees
Structural Formula:

115

Use:pharmaceutical, automobile industry, explosive

synthetic method:

(1) It is obtained by the action of hydrazine sulfate and lime nitrogen and neutralization with sulfuric acid to form salt: first, suspend hydrazine sulfate in water, gradually add lime nitrogen under cooling and agitation, control the temperature at about 20 ℃, react for 8h, then filter, wash the filter cake with water, and drain; combine the filtrate and washing solution, neutralize with 50% sulfuric acid at room temperature to pH = 5, filter and remove calcium sulfate, and concentrate the mother liquor through decompression After cooling, white crystals are precipitated, washed with ice water and dried, the yield is about 72%. (2) From the reaction of methyl isothiourea sulfate and hydrazine hydrate, 119ml 42% hydrazine hydrate solution was diluted with equal volume of water, and then it was added to 139g of methyl isothiourea sulfate in 200ml aqueous solution at a temperature of 10 ℃. The methyl mercaptan released from the reaction is absorbed into the sodium hydroxide solution. After the reaction solution is concentrated to 200ml, 95% ethanol of the same volume is added, namely, aminoguanidine sulfate is separated out, and crystallization is filtered out. The mother liquor can also be partially crystallized. Drying the crystal in
