Guanidine carbonate Chemical Properties,Usage,Production

High purity Guanidine carbonate synthesis method Guanidine carbonate is an extremely versatile organic chemical products, it is mainly used in flame retardants, flocculants, foaming agents, synthetic sulfa drugs, etc. Guanidine carbonate is also used as synthetic detergent builders, high-quality cosmetics raw materials.Synthesis of guanidine carbonate is reported by many literatures [1-3] .The main domestic guanidine carbonate production is that molt dicyandiamide and ammonium chloride to generate guanidine hydrochloride, generate free guanidine under the action of the alkali, and then by the reaction of free guanidine and carbon dioxide to produce guanidine carbonate. this route is easy to generate melamine and its dimers, trimers and other impurities because of the high-temperature melting , and the presence of Cl-, Na + in the system is difficult to completely removed , even if the purity is> 99% of guanidine carbonate, its ash content is still up 0.2%, it is difficult to obtain high purity guanidine carbonate. in this paper, cyanamide as raw materials, reacts with carbon dioxide and ammonia in one step synthesis of guanidine carbonate, also known as ash-free guanidine carbonate, and then purify , to obtain a high purity guanidine carbonate, the reaction equation is as follows: 2NH2CN + CO2 + 2NH3 + H20 → [NH2C (: NH) NH2] 2H2CO3

Uses Guanidine Carbonate is used in the cytidine triphosphate injection stabilization. It also acts as a powerful and versatile protein denaturants.
As a strong chemical base, guanidine carbonate is used as an intermediary in a variety of applications:
Organic synthesis materials and analytical reagents.
pH adjusting agents for amino resins, antioxidants, resin stabilizer and guanidine soap, also a grout agent, cement additives, surfactants.
In terms of synthetic detergent,it is used as a moisture agent and a synergist.
For Zinc, cadmium, manganese weight measurement, it is used as a precipitating agent, it is also used in the separation of alkali metal magnesium.
Uses Guanidine Carbonate is a strong organic alkali. It is used to adjust the pH of a formulation, organic intermediate, soap and cosmetic products.
Application Guanidine carbonate salt can be used as a reactant for the synthesis of:
An oxidizer, guanidinium dinitramide (GDN), by reacting with ammonium dinitramide.
Guanidinium cyclopropanecarboxylate by reacting with cyclopropanecarboxylic acid.
Preparation Synthesis of guanidine carbonate: Melt double cyanide salts and ammonia to generate guanidine salts (guanidine hydrochloride, guanidine nitrate) at 170-230 ℃ . Then make guanidine salt into an alcohol solution, add soda to free guanidine, absorb carbon dioxide to obtain guanidine carbonate.
