Aminoguanidine bicarbonate(casno:2582-30-1) use
Aminoguanidine Bicarbonate is used as an intermediate for the synthesis of pharmaceuticals, agrochemicals, dyestuffs and other organic derivatives (photochemicals, explosives). Aminoguanidine Bicarbonate is used in the purification of acrylic acid to remove aldehydes. Aminoguanidine Bicarbonate is used as a selective inhibitor of inducible nitric oxide synthase in biochemistry.
Aminoguanidine Bicarbonate is a starting compound for the manufacture of the explosive tetracene, which finds wide applications in primer compositions and explosive rivets. Aminoguanidine Bicarbonate is also an intermediate in the manufacturing of selective weed killers (3-amino-1,2,4-triazole). Since aminoguanidine bicarbonate has good selective reducing properties it has been used by the dye, pharmaceutical and photographic industries. When combined with phosphoric acid forms a complex that can act as a flame retardant in fibrous cellulose and protein materials.
Aminoguanidine bicarbonate(casno:2582-30-1) handling
Avoid contact with skin and avoid ingestion. Use dust respirator when handling. Since no exposure limit have been established for aminoguanidine bicarbonate by OSHA & ACGIH, we recommend that our product should be treated as a nuisance dust 15 mg/m3. Product must be stored below 30oC(85oF) to reduce the risk of decomposition and discoloration. See MSDS for more information.
preparing high-purity aminoguanidine bicarbonate(Casno:2582-30-1) Method
The invention relates to a method for preparing high-purity aminoguanidine bicarbonate(Casno:2582-30-1). The technological process comprises the steps that hydrazine hydrate and water are mixed firstly; hydrogen cyanamide is added after the temperature rises to 66-80 DEG C; a mixed solution is heated continuously to 80 DEG C; then heating is stopped, so that the temperature of the solution drops naturally to 75-77 DEG C; heat preservation is conducted for 4 hours; then ammonium bicarbonate is added, carbon dioxide gas is introduced at the same time, and heat preservation is conducted for 4 hours; and suction filtration, separation, ethanol rinsing and drying are performed to obtain the high-purity aminoguanidine bicarbonate(Casno:2582-30-1). According to the method, cyanamide, the hydrazine hydrate and the ammonium bicarbonate serve as raw materials to produce the aminoguanidine bicarbonate(Casno:2582-30-1), and the carbon dioxide gas is introduced into the mother liquid for adjusting the pH value of the mother liquid during the process for producing the aminoguanidine bicarbonate(Casno:2582-30-1) simultaneously, so that the product purity is improved. The product purity of the aminoguanidine bicarbonate(Casno:2582-30-1) produced through the method ranges from 98.5% to 99%.
aminoguanidine bicarbonate(Casno:2582-30-1) synthesis technology
Casno:2582-30-1 was synthesized using hydrazine hydrate,lime nitrogen,sulfuric acid and ammonium bicarbonate as raw materials.Factors were investigated including the material ratio(hydrazine hydrate:lime nitrogen),water consumption,pH value and reaction temperature.The results show that optimum reaction conditions:is follow:the dose of water is 100 mL,reaction temperature is 45℃,the mole ratio of hydrazine hydrate to lime nitrogen is 1∶2,pH value is 7.2-7.5,heat for three hours at 70℃.The optimum conditions of crystallization are the crystallization temperature of 10℃ and the crystallization time of 4 hours.In this condition,the yield of products is 96.07% and the product purity is 98%.
Carbonate and Semicarbazide Tin(IV) Derivatives of aminoguanidine bicarbonate(Casno:2582-30-1)
ABSTRACT Equimolar reactions between organotin(IV) precursors of SnClxR4-x (R = Bu, Ph, x = 1, 4) and aminoguanidine bicarbonate(Casno:2582-30-1) in methanol has afforded 2:1 and 1:1 (M:L) carbonate complexes as well as 1:2 semicarbazide derivative. The products were characterised by spectroscopic methods such as multinuclear NMR (H-1, C-13 and Sn-119), Myssbauer and infrared spectroscopy as well as microanalysis and melting point. The butyl and phenyl derivatives have a 4- and 5-coordinated metal centre respectively with bridging-bidentate and bridging-tridentate carbonate. For the tetrahalide metal precursor, a 6-coordinated tin(IV) derivative has been achieved with a bidentate semicarbazide towards the metal centre.
