calcium cyanamide is what? this looks strange substance, is actually a commonly used chemical reagents. Its molecular formula is Ca(CN)2, the chemical name is dicalcium hydrocyanate, which is a white crystalline powder formed by the reaction of hydrocyanic acid and calcium hydroxide, and is insoluble in water. In practical applications, it is mainly used in metal surface treatment, rubber processing, organic synthesis and other industries.

So, what are the ingredients of calcium cyanamide? First, it contains two ions, one is the calcium ion Ca2, and the other is the cyanide ion CN-. These two ions play an important role in the process of calcium cyanamide. In addition, dicalcium hydrocyanate also contains a trace of moisture, which is due to its powder in the air to absorb moisture.

the effect of calcium cyanamide, mainly based on the cyanide ions contained in it, which under specific conditions will dissociate into hydrogen cyanide HCN and hydroxide ions OH-. Hydrogen cyanide is a toxic gas, but after neutralization, it can become harmless cyanide substances. Therefore, calcium cyanamide can be used as a cyanating agent in organic synthesis. In addition, because it can remove the oxide on the metal surface, it can be used as a cleaning and deoxidizing agent.

for the use of calcium cyanamide precautions, first of all, its toxicity is very strong, not only will cause harm to the human body, but also pollute the environment. Therefore, in the process of use, we must strictly grasp the method of use and the amount of use, and take appropriate protective measures to avoid accidents. In addition, in the process of storage and transportation, it is also necessary to pay attention to safety issues such as moisture-proof and explosion-proof.

To sum up, calcium cyanamide is a commonly used chemical reagent, mainly used in metal surface treatment, rubber processing, organic synthesis and other industries. Its main components are calcium ions and cyanide ions, and the principle of action is based on the cyanide ions contained therein. In actual use, attention should be paid to its toxicity and safety issues. I hope this article can help you understand calcium cyanamide.
