Deskripsyon Product

Dicyandiamine, abbreviated DICY or DCD. It is an organic compound with the chemical formula C2H4N4, which is a dimer of cyanamide and a cyanide derivative of guanidine. Chemical formula C2H4N4. White crystalline powder. Soluble in water, alcohol, ethylene glycol and dimethylformamide, almost insoluble in ether and benzene. Stable when dry.

 

Karakteristik

Properties: white crystalline powder. The solubility in water is 2.26% at 13℃, and the solubility is larger in hot water. When the aqueous solution is gradually decomposed at 80℃, ammonia gas is produced. The solubility of anhydrous ethanol (C2H5OH) and ether is 1.26% and 0.01% respectively at 13℃. Soluble in liquid ammonia, hot water, ethanol, acetone hydrate, dimethylformamide, insoluble in ether, insoluble in benzene and chloroform. The relative density (d254) is 1.40. Melting point 209.5℃. Stable when dry. It doesn't burn. Low toxicity, median lethal dose (mice, oral)>4000mg/kg. The maximum allowable concentration in the air is 5mg/m³.

 

Aplikasyon

【 Use 1 】
It is the raw material of melamine and an intermediate in the synthesis of medicine, pesticides and dyes
【 Use 2 】
It is used in organic synthesis and resin synthesis, and is also used as a vulcanization accelerator and hardener
【 Use 3 】
It is the raw material for the production of melamine. It is also an intermediate in medicine and dyes. In medicine, it is used to prepare guanidine nitrate, sulfonamides and so on. It can also be used to produce thiourea, guanidine, cellulose nitrate stabilizer, rubber vulcanization accelerator, steel surface hardener, dyeing and dyeing fixing agent, artificial leather filler and adhesive.
【 Use 4 】
The main uses of dicyandiamine are: (1) as guanidine salt, melamine diamines raw materials. Various guanidine salts can be produced by reacting dicyandiamide with acid. The reaction of dicyandiamide and phenylnitrile to phenylmelamine diamine is an intermediate in coatings, laminates and molding powders. (2) Used as dye fixing agent, dicyandiamide resin prepared by reaction of dicyandiamide and formaldehyde can be used as dye fixing agent. (3) dicyandiamide fertilizer, dicyandiamide complex fertilizer can control the activities of nitrifying bacteria, so that the conversion rate of nitrogen fertilizer in the soil can be adjusted, reduce nitrogen loss, and improve the efficiency of fertilizer use. (4) As a fine chemical intermediate. In medicine, it is used to prepare guanidine nitrate, sulfonamides, etc.; It is also used to produce thiourea, cellulose nitrate stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive and so on. The pharmaceutical intermediate 5-azacytosine can be obtained by the reaction of dicyandiamide with formic acid.

Spesifikasyon

 

Product knowledge

Test cobalt, nickel, copper and palladium. Organic synthesis. Nitrocellulose stabilizer. Hardener. Detergent. Vulcanization accelerator. Resin synthesis.
Used as a latent curing agent of epoxy resin adhesive, the formulation of a single component epoxy adhesive, only when the particle size of diamine is less than 5μm(2500 mesh), can form a suspension in the epoxy resin, without precipitating. The reference dosage is 4 ~ 12 parts, and the application period of 100g epoxy resin composition is 6 ~ 12 months. The storage period of dicyandiamine is less than 2 months when the dosage is 17 parts, and the storage period can reach half a year when the dosage is 8 parts. The curing conditions are 170℃/lh or 180℃/20min, and the thermal deformation temperature is 125℃. Also used as a hardener for one component aqueous epoxy adhesives. Reference dosage 7 copies. The combination system of dicyandiamine (5 ~ 6 parts) and hydrazide (3 ~ 4 parts) can cure epoxy resin at 120℃/45min.
