Description

Dicyandiamide, DCDA, N-cyanoguanidine

Molecular weight 84.03. Colorless crystal. Poorly soluble in water.

The dicyandiamide is a nitrile derived from guanidine. This is a dimer of cyanimide from which it can be prepared. Dicyandiamide is a colorless solid that soluble in water, acetone and alcohol, but not nonpolar organic solvents.

Solubility in water of 3.3% at 20°C. Not hygroscopic. Soluble in alcohol, worse-in the air. Melting t 210°C. the Density of 1,386-1,405 g/cm3. The heat of formation is 24.9 kJ / mol. The heat of combustion is 1382 kJ / mol. Heat capacity at 298.15 K 1674 j / (kg·K), thermal conductivity of 0.85 W/(m·K).

Low toxicity, but with systematic contact causes dermatitis. Obtained by dimerization of cyanimide, which in turn is obtained from calcium cyanimide.

Application

In the chemical industry, Dicyandiamide is used as a raw material for the production of hot-curing epoxy resins, glue, for the synthesis of guanidine and melamine.

Use it as a binder for varnishes and paints. It can be used as a raw material for the production of plastics.

In the pharmaceutical industry-in the process of synthesis of antimicrobial drugs.

In light industry, it is used as a binder for dyeing fabrics.

In the wood industry, Dicyandiamide is indispensable as a component of fire (flame retardant) impregnation for wood products.

Used as a product in the org. synthesis, as a stabilizer of nitrocellulose, fertilizer. In the manufacture of organic fertilizers, it is used as a reagent as an activator.

It is used in pyrotechnics as fuel, which has the properties of a flame arrestor, and therefore it is used in signal smoke compositions. It is also used in gas-generating compositions of pyrotechnic fountains.
