Peculiarities Of Calcium Carbide

Calcium carbide is a strong element with a crystalline structure. The final shade depends on the quality of the raw materials and can vary from bluish to purple, black. In addition, an undesirable smell reminiscent of garlic may appear. The process of merging with water and solutions of mineral acids or alkalis is of industrial importance, as it generates a large amount of heat.

The reaction of calcium carbide with water is represented by the following formula: CaC2 + 2H2O = Ca(OH)2 + C2H2.
As a result of this reaction, acetylene, an unsaturated hydrocarbon with a triple bond, is also formed.

The reaction of decomposition of calcium carbide by oxygen occurs only under the influence of elevated temperatures (700 - 900 °C): 2CaC2 + 5O2 → 2CaO + 4CO2.

As for the storage and transportation of calcium carbide, it must be packed in moisture-proof containers or tanks. This is necessary in order to exclude the ingress of moisture and prevent the decomposition process. Care must be taken both when packing and unpacking. It is also necessary to refrain from using tools that create sparks during operation.
Given the dangerous nature of carbide penetration into the human body and skin, it is necessary to provide all persons involved in the process with appropriate protective equipment.
Transportation should be carried out exclusively by cars with a closed body. It should be noted that shipping by air is strictly prohibited.
It is necessary to provide a ventilation system in the production premises and prohibit the storage of the product together with other goods.
