Burning chlorine

Any plant at times produces unwanted isomers. This requires an incinerator, capable of burning chlorinated hydrocarbons to HCl, H2O, and CO2 equipped with an efficient absorber for HCl (see Incinerators). An alternative to burning is dechlorination using hydrogen over a suitable catalyst. The ultimate product could be benzene. 

Hydrogen chloride is produced by burning chlorine with an excess of hydrogen. The reaction is highly exothermic and reaches equilibrium very rapidly. The equilibrium mixture contains approximately 4 per cent free chlorine but this is rapidly combined with the excess hydrogen as the mixture is cooled. Below 200°C the conversion of chlorine is essentially complete. 

Chlorine does not burn but, like oxygen, it helps other substances burn. Chlorine is a strong oxidizing agent (a chemical substance that takes on electrons from another substance). 

Arises from burning chlorinated hydrocarbons, e.g. trichloro-ethylene. Effects similar to nitrous oxide. 

Sodium is a soft, siivery metal.This metal cannot be handled with bare fingers, because it reacts with any moisture on the skin, causing a burn. Chlorine is a poisonous, greenish-yeiiow gas with a choking odor. When molten sodium is placed into an atmosphere of chlorine, a dramatic reaction occurs the sodium bursts into flame and a white, crystalline powder forms (see Figure 2.1). What is particularly interesting about this reaction is that this chemical combination of two toxic substances produces sodium chloride, the substance that we commonly call table salt. 

There are a few producers of HCI for external sale. Most HCI production is used cap-tively by its producer. These producers manufacture hydrochloric acid by burning chlorine gas with hydrogen.
