Chlorine

Cl

Colorless or yellowish gas. It is usually presented in the form of an aqueous solution without color and pungent odor.

It comes from the electrolysis of sodium chloride and is then cooled, filtered, dried, purified and compressed to allow its liquefaction and storage.

Water treatment and chemical industry, in particular in the manufacture of polyurethanes (MDI and TDI) and PVC. Also used for disinfecting drinking water and swimming pools, wastewater treatment and cooling, in the textile industry and in the production of paper pulp.

Its name comes from the Greek “khlorós”, which means greenish. In 1648, the German chemist Johann Rudolf Glauber was the first to detect it, heating moist salt in a coal furnace and condensing the resulting vapors. It wasn't until 1774 that chlorine was isolated for the first time; the Swede Carl Wilhelm Scheele described the gas but didn't realize that it was an element. It wasn't until 1810 that the Englishman Humphry Davy identified and baptized it.

In bulk or packed in containers or bottles.
