Applications · 2 items
UsesGuanidine Carbonate is a strong organic alkali. It is used to adjust the pH of a formulation, organic intermediate, soap and cosmetic products.
UsesGuanidine 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.

PreparationSynthesis 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.
