Chlorine can be manufactured by the electrolysis of a sodium chloride solution (), which is known as the Chloralkali process.The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H 2).
Old drawing of a chloralkali process plant (Edgewood, Maryland) The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions. It is the technology used to produce chlorine and sodium hydroxide (caustic soda), [1] which are
Chlorine pentafluoride (ClF 5) is made on a large scale by direct fluorination of chlorine with excess fluorine gas at 350 °C and 250 atm, and on a small scale by reacting metal chlorides with fluorine gas at 100–300 °C. It melts at −103 °C and boils at −13.1 °C.
In a paper published in 1894, it was formally proposed to add chlorine to water to render it "germ-free". Two other authorities endorsed this proposal and published it in many other papers in 1895. [4] Early attempts at implementing water chlorination at a water treatment plant were made in 1893 in Hamburg, Germany.
The solution travels to a tank that separates the hydrogen gas based on its low density. [1] Only water and sodium chloride are used. The simplified chemical reaction is: NaCl + H 2 O + energy → NaOCl + H 2 [citation needed] That is, energy is added to sodium chloride (table salt) in water, producing sodium hypochlorite and hydrogen gas.

In 2002 in Missouri, a flex hose ruptured during unloading a train car at a chemical plant, releasing approximately 16,900 pounds (7,700 kg) of chlorine gas. 67 persons were injured. [1] In 2004 in Macdona, Texas, a freight train accident released 9,400 US gallons (36,000 L; 7,800 imp gal) of chlorine gas and other toxic chemicals. At least 40 ...
