Guanidine Carbonate *9% min Molecular formula: C2H*0N6·H2CO3 Molecular Weight: **0.*7 CAS No. :*******1 Packing: *5kg plastic woven bag lined with PE bag(*8MT/FCL). Properties: white crystalline powder. Melting point **8 ℃ (partial decomposition), the relative density of 1.*5 (*0 / 4 ℃). *5 ℃, 4% aqueous solution of pH = *1.2. *0 ℃ **0g when the solubility of the following solution: *2g/**0g water, 0.*5g/**0g methanol. Almost insoluble in acetone, benzene and ether. The above solution slowly at *0 ℃ hydrolysis, release of ammonia and urea formation. Preparation Methods: Two-ammonia and ammonium cyanide melt at ******0 ℃ reaction of guanidine (guanidine hydrochloride, guanidine nitrate). Guanidine alcohol solution then made, plus guanidine free base and in so out of carbon dioxide reaction that may guanidine carbonate. Usage: organic synthesis of raw materials and reagents. PH value for the amino resin modifier, antioxidant, stabilizer and guanidine resin soap, etc., are also used as a thin slurry of cement agent, surfactant additives. Synthetic detergent, the use of moisture agent and synergist. Zinc, cadmium, manganese weight determination, as precipitating agent, also used for the separation of alkali metal magnesium.
