Membrane cell electrolysis employs permeable membrane as an ion exchanger. Saturated sodium or potassium chloride solution is passed through the anode compartment, leaving at a lower concentration.
This method also produces very pure sodium or potassium hydroxide but has the disadvantage of requiring very pure brine at high concentrations.
In the Deacon process , hydrogen chloride recovered from the production of organochlorine compounds is recovered as chlorine.
The process relies on oxidation using oxygen:. The reaction requires a catalyst. As introduced by Deacon, early catalysts were based on copper.
Commercial processes, such as the Mitsui MT-Chlorine Process, have switched to chromium and ruthenium-based catalysts. Sodium chloride is by a huge margin the most common chlorine compound, and it is the main source of chlorine and hydrochloric acid for the enormous chlorine-chemicals industry today.
About chlorine-containing compounds are commercially traded, including such diverse compounds as chlorinated methanes and ethanes , vinyl chloride and its polymer polyvinyl chloride PVC , aluminium trichloride for catalysis , the chlorides of magnesium , titanium , zirconium , and hafnium which are the precursors for producing the pure elements, and so on.
Other particularly important organochlorines are methyl chloride , methylene chloride , chloroform , vinylidene chloride , trichloroethylene , perchloroethylene , allyl chloride , epichlorohydrin , chlorobenzene , dichlorobenzenes , and trichlorobenzenes.
This was done in "gut factories" boyauderies , and it was an odiferous and unhealthy process. The same chemicals were found to be useful in the routine disinfection and deodorization of latrines , sewers , markets, abattoirs , anatomical theatres , and morgues.
In , the contagion of infections was well known, even though the agency of the microbe was not discovered until more than half a century later. During the Paris cholera outbreak of , large quantities of so-called chloride of lime were used to disinfect the capital.
This was not simply modern calcium chloride , but chlorine gas dissolved in lime-water dilute calcium hydroxide to form calcium hypochlorite chlorinated lime.
Chloride of lime was used for destroying odors and "putrid matter". One source claims chloride of lime was used by Dr.
John Snow to disinfect water from the cholera-contaminated well that was feeding the Broad Street pump in London,  though three other reputable sources that describe that famous cholera epidemic do not mention the incident.
A modified version of this solution continues to be employed in wound irrigation in modern times, where it remains effective against bacteria that are resistant to multiple antibiotics see Century Pharmaceuticals.
The first continuous application of chlorination to drinking U. Chlorine is presently an important chemical for water purification such as in water treatment plants , in disinfectants , and in bleach.
Even small water supplies are now routinely chlorinated. Chlorine is usually used in the form of hypochlorous acid to kill bacteria and other microbes in drinking water supplies and public swimming pools.
In most private swimming pools, chlorine itself is not used, but rather sodium hypochlorite , formed from chlorine and sodium hydroxide , or solid tablets of chlorinated isocyanurates.
The drawback of using chlorine in swimming pools is that the chlorine reacts with the proteins in human hair and skin. As a disinfectant in water, chlorine is more than three times as effective against Escherichia coli as bromine , and more than six times as effective as iodine.
It is often impractical to store and use poisonous chlorine gas for water treatment, so alternative methods of adding chlorine are used.
These include hypochlorite solutions, which gradually release chlorine into the water, and compounds like sodium dichloro-s-triazinetrione dihydrate or anhydrous , sometimes referred to as "dichlor", and trichloro-s-triazinetrione , sometimes referred to as "trichlor".
These compounds are stable while solid and may be used in powdered, granular, or tablet form. When added in small amounts to pool water or industrial water systems, the chlorine atoms hydrolyze from the rest of the molecule forming hypochlorous acid HOCl , which acts as a general biocide, killing germs, micro-organisms, algae, and so on.
It also tasted metallic and stung the back of the throat and chest. Chlorine reacts with water in the mucosa of the lungs to form hydrochloric acid , destructive to living tissue and potentially lethal.
Human respiratory systems can be protected from chlorine gas by gas masks with activated charcoal or other filters, which makes chlorine gas much less lethal than other chemical weapons.
It was pioneered by a German scientist later to be a Nobel laureate, Fritz Haber of the Kaiser Wilhelm Institute in Berlin, in collaboration with the German chemical conglomerate IG Farben , which developed methods for discharging chlorine gas against an entrenched enemy.
Chlorine gas was also used during the Iraq War in Anbar Province in , with insurgents packing truck bombs with mortar shells and chlorine tanks.
The attacks killed two people from the explosives and sickened more than Most of the deaths were caused by the force of the explosions rather than the effects of chlorine since the toxic gas is readily dispersed and diluted in the atmosphere by the blast.
In some bombings, over a hundred civilians were hospitalized due to breathing difficulties. The Iraqi authorities tightened security for elemental chlorine, which is essential for providing safe drinking water to the population.
The Syrian government allegedly uses chlorine as a chemical weapon ,  often dropping it in barrel bombs ,  but sometimes also in rockets.
The chloride anion is an essential nutrient for metabolism. Chlorine is needed for the production of hydrochloric acid in the stomach and in cellular pump functions.
Overly low or high concentrations of chloride in the blood are examples of electrolyte disturbances. Hypochloremia having too little chloride rarely occurs in the absence of other abnormalities.
It is sometimes associated with hypoventilation. When symptoms do occur, they tend to resemble those of hypernatremia having too much sodium.
Reduction in blood chloride leads to cerebral dehydration; symptoms are most often caused by rapid rehydration which results in cerebral edema.
Hyperchloremia can affect oxygen transport. Chlorine is a toxic gas that attacks the respiratory system, eyes, and skin. Chlorine gas is a strong oxidizer, which may react with flammable materials.
Chlorine is detectable with measuring devices in concentrations as low as 0. When used at specified levels for water disinfection, the reaction of chlorine with water is not a major concern for human health.
Other materials present in the water may generate disinfection by-products that are associated with negative effects on human health.
The National Institute for Occupational Safety and Health has designated a recommended exposure limit of 0. In the home, accidents occur when hypochlorite bleach solutions come into contact with certain acidic drain-cleaners to produce chlorine gas.
Chlorine is widely used for purifying water, especially potable water supplies and water used in swimming pools. Several catastrophic collapses of swimming pool ceilings have occurred from chlorine-induced stress corrosion cracking of stainless steel suspension rods.
Both materials were used in hot and cold water domestic plumbing, and stress corrosion cracking caused widespread failures in the US in the s and s.
The adjacent picture shows a fractured acetal joint in a water supply system. The cracks started at injection molding defects in the joint and slowly grew until the part failed.
The fracture surface shows iron and calcium salts that were deposited in the leaking joint from the water supply before failure. The element iron can combine with chlorine at high temperatures in a strong exothermic reaction, creating a chlorine-iron fire.
