What is Disyandiamide?
Dicyandiamide (C2H4N4) is an organic compound with the formula CH2(CN)2. It is a white crystalline solid that is readily soluble in water but insoluble in many organic solvents. It is used as a versatile intermediate in the chemical industry.
- It plays an important role as a raw material, especially in urea production.
- It is evaluated in areas such as polymer and resin production, insecticides, and high-strength plastics.
- Thanks to its high nitrogen content, it is also used as a fertilizer additive.
- It also plays a role as a monomer in the production of superabsorbent polymers.
As a result, disiyandiamide is a chemical raw material of strategic importance for many industries.

How is Disyandiamide Produced?
Dicyandiamide production is typically carried out using propylene, ammonia, and hydrogen. The process consists of three stages:
- Oxidation of propylene:
- Propylene is oxidized and converted into acetic acid.
- Hydrogenation step:
- Acetonitrile, propylene, hydrogen, and ammonia gases are added to the reactor.
- BAt this stage, acetonitrile reacts with hydrogen to form dicyandiamide and a certain amount of pentanitrile.
- Separation processes:
- Dicyandiamide is isolated from pentanitrile.
- Purification and refinement processes are carried out to obtain the pure product.
This method is the most widely used production process on an industrial scale. However, alternative methods are also available.
