Dicyandiamide manufacturers summarize the top 5 uses of dicyandiamide
Dicyandiamide Manufacturer
The manufacturer of dicyandiamide informs you that it can be used as a flocculant in water treatment, a color-fixing agent in the dyeing industry, to produce formaldehyde resin through condensation reactions with formaldehyde, and to manufacture various guanidine salts.
Properties: It is a white crystalline powder. Its solubility in water at 13°C is 2.26%, and it is more soluble in hot water. The aqueous solution decomposes slowly at 80°C, releasing ammonia gas. Its solubility in anhydrous ethanol is 1.26%, and in ether it is 0.01%. It dissolves in liquid ammonia, hot water, ethanol, acetone hydrate, and dimethyl formamide, but is insoluble in ether, benzene, and chloroform. Its relative density (d254) is 1.40. The melting point is 209.5°C. It is stable during drying and does not burn. It is low in toxicity, with a median lethal dose (oral, in mice) >4000 mg/kg. The maximum allowable concentration in air is 5 mg/m³.
Summary of Dicyandiamide’s 5 Major Uses:
- As a Potential Curing Agent for Epoxy Resins: It can be used to prepare single-component epoxy adhesives.
- As a Raw Material for Guanidine Salts and Melamine Dimers: Various salts can be prepared through reactions with acids. Dicyandiamide reacts with benzonitrile to produce cyanuric acid, an intermediate for coatings, laminates, and molding powders.
- As a Color-Fixing Agent: Dicyandiamide resin, obtained by reacting with formaldehyde, can be used as a color-fixing agent.
- Dicyandiamide Fertilizer: Dicyandiamide compound fertilizers can control the activity of nitrifying bacteria, regulate the conversion rate of nitrogen fertilizers in the soil, reduce nitrogen loss, and improve fertilizer utilization.
- As a Fine Chemical Intermediate: It can also be used to prepare guanidine nitrate, sulfonamides, thiourea, nitrocellulose stabilizers, rubber vulcanization accelerators, steel surface hardeners, synthetic leather packaging, adhesives, etc. In pharmaceuticals, 5-azacytidine is produced by reacting dicyandiamide with formic acid. It is also used as a nitrogen source for carbon material doping.
