Hexachloroethane
Encyclopedia
Hexachloroethane, also known as perchloroethanes (PCA), C2
Cl6
, is a colorless solid at room temperature which is used by the US Military in smoke composition
s, e.g. in contemporary base-eject smoke munitions
(smoke grenades).
Hexachloroethane is used in most aluminium
foundries
around the world to remove hydrogen.
Hexachloroethane is susceptible to reduction
reactions as the result of the electron deficiency on the carbon
atoms. It has a half-life
of 36 minutes in a reductive environment.
Carbon
Carbon is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds...

Smoke composition
A smoke composition is a pyrotechnic composition designed primarily to generate smoke. Smoke compositions are used as obscurants or for generation of signaling smokes. Some are used as a payload of smoke bombs and smoke grenades.-Obscurants:...

Foundry
A foundry is a factory that produces metal castings. Metals are cast into shapes by melting them into a liquid, pouring the metal in a mold, and removing the mold material or casting after the metal has solidified as it cools. The most common metals processed are aluminum and cast iron...

Half-life
Half-life, abbreviated t½, is the period of time it takes for the amount of a substance undergoing decay to decrease by half. The name was originally used to describe a characteristic of unstable atoms , but it may apply to any quantity which follows a set-rate decay.The original term, dating to...
