How Is Tetracarbon Decachloride Synthesized?

Tetracarbon decachloride, also known as carbon tetrachloride, is typically synthesized by the reaction of chlorine gas with tetrachloromethane (CCl4) in the presence of a catalyst such as aluminum chloride (AlCl3). The reaction proceeds through a series of intermediate compounds, ultimately forming tetracarbon decachloride and hydrogen chloride gas:

CCl4 + Cl2 -> CCl5Cl

CCl5Cl + Cl2 -> CCl4 + CCl6

CCl6 + Cl2 -> CCl5Cl + CCl3Cl

CCl5Cl + Cl2 -> CCl4 + CCl7

CCl7 + Cl2 -> CCl6 + CCl5Cl

CCl5Cl + Cl2 -> CCl4 + CCl8

CCl8 + Cl2 -> CCl6 + CCl6

CCl6 + Cl2 -> CCl5Cl + CCl4

CCl5Cl + Cl2 -> CCl4 + CCl9

CCl9 + Cl2 -> CCl7Cl + CCl4

CCl7Cl + Cl2 -> CCl6 + CCl5Cl

CCl5Cl + Cl2 -> CCl4 + CCl10

The final product, tetracarbon decachloride, can be purified by distillation. It is important to note that tetracarbon decachloride is a highly toxic and carcinogenic substance, and its use has been restricted or banned in many countries due to its harmful effects on human health and the environment.
