Chlorine dioxide is a chemical compound with the formula ClO2 that exists as yellowish-green gas above 11 °C, a reddish-brown liquid between 11 °C and −59 °C, and as bright orange crystals below −59 °C. It is an oxidizing agent, able to transfer oxygen to a variety of substrates, while gaining one or more electrons via oxidation-reduction (redox). It does not hydrolyze when it enters water, and is usually handled as a dissolved gas in solution in water. Potential hazards with chlorine dioxide include health concerns, explosiveness and fire ignition.[5] It is commonly used as a bleach.

Chlorine dioxide was discovered in 1811 by Sir Humphry Davy and has been widely used for bleaching purposes in the paper industry, and for treatment of drinking water.[6] More recent developments have extended its application into food processing, disinfection of premises and vehicles, mold eradication, air disinfection and odor control, treatment of swimming pools, dental applications, and wound cleansing.

The compound has been fraudulently marketed as an ingestible cure for a wide range of diseases, including childhood autism[7] and COVID-19.[8][9][10] Children who have been given enemas of chlorine dioxide as a supposed cure for childhood autism have suffered life-threatening ailments.[7] The U.S. Food and Drug Administration (FDA) has stated that ingestion or other internal use of chlorine dioxide (other than perhaps oral rinsing under dentist supervision) has no health benefits and it should not be used internally for any reason.[11][12]

Structure and bonding

Comparison of three-electron bond to the conventional covalent bond
The two resonance structures

Chlorine dioxide is a neutral chlorine compound. It is very different from elemental chlorine, both in its chemical structure and in its behavior.[13] One of the most important qualities of chlorine dioxide is its high water solubility, especially in cold water. Chlorine dioxide does not hydrolyze when it enters water; it remains a dissolved gas in solution. Chlorine dioxide is approximately 10 times more soluble in water than chlorine.[13]

The molecule ClO2 has an odd number of valence electrons, and therefore, it is a paramagnetic radical. Its electronic structure has long baffled chemists because none of the possible Lewis structures is very satisfactory. In 1933, L. O. Brockway proposed a structure that involved a three-electron bond.[14] Chemist Linus Pauling further developed this idea and arrived at two resonance structures involving a double bond on one side and a single bond plus three-electron bond on the other.[15] In Pauling's view the latter combination should represent a bond that is slightly weaker than the double bond. In molecular orbital theory this idea is commonplace if the third electron is placed in an anti-bonding orbital. Later work has confirmed that the highest occupied molecular orbital is indeed an incompletely-filled antibonding orbital.[16]

Preparation

Chlorine dioxide is a compound that can decompose extremely violently when separated from diluting substances. As a result, preparation methods that involve producing solutions of it without going through a gas-phase stage are often preferred. Arranging handling in a safe manner is essential.

Oxidation of chlorite

In the laboratory, ClO2 can be prepared by oxidation of sodium chlorite with chlorine:[17]

2 NaClO2 + Cl2 → 2 ClO2 + 2 NaCl

Traditionally, chlorine dioxide for disinfection applications has been made from sodium chlorite or the sodium chlorite–hypochlorite method:

2 NaClO2 + 2 HCl + NaOCl → 2 ClO2 + 3 NaCl + H2O

or the sodium chlorite–hydrochloric acid method:

5 NaClO2 + 4 HCl → 5 NaCl + 4 ClO2 + 2 H2O

or the chlorite–sulfuric acid method:

4 ClO−
2 + 2 H2SO4 → 2 ClO2 + HClO3 + 2 SO2−
4 + H2O + HCl

All three methods can produce chlorine dioxide with high chlorite conversion yield. Unlike the other processes, the chlorite–sulfuric acid method produces completely chlorine-free chlorine dioxide, although it suffers from the requirement of 25% more chlorite to produce an equivalent amount of chlorine dioxide. Alternatively, hydrogen peroxide may be efficiently used in small-scale applications.[13]

Reduction of chlorate

In the laboratory, chlorine dioxide can also be prepared by reaction of potassium chlorate with oxalic acid:

2 KClO3 + 2 H2C2O4 → K2C2O4 + 2 ClO2 + 2 CO2 + 2 H2O

or with oxalic and sulfuric acid:

2 KClO3 + H2C2O4 + 2 H2SO4 → 2 KHSO4 + 2 ClO2 + 2 CO2 + 2 H2O

Over 95% of the chlorine dioxide produced in the world today is made by reduction of sodium chlorate, for use in pulp bleaching. It is produced with high efficiency in a strong acid solution with a suitable reducing agent such as methanol, hydrogen peroxide, hydrochloric acid or sulfur dioxide.[13] Modern technologies are based on methanol or hydrogen peroxide, as these chemistries allow the best economy and do not co-produce elemental chlorine. The overall reaction can be written as:[18]

chlorate + acid + reducing agent → chlorine dioxide + by-products

As a typical example, the reaction of sodium chlorate with hydrochloric acid in a single reactor is believed to proceed through the following pathway:

ClO−
3 + Cl−
 + H+
 → ClO−
2 + HOCl
ClO−
3 + ClO−
2 + 2 H+
 → 2 ClO
2 + H
2O
HOCl + Cl−
 + H+
 → Cl
2 + H
2O

which gives the overall reaction

2 ClO−
3 + 2 Cl−
 + 4 H+
 → 2 ClO
2 + Cl
2 + 2 H
2O.

The commercially more important production route uses methanol as the reducing agent and sulfuric acid for the acidity. Two advantages of not using the chloride-based processes are that there is no formation of elemental chlorine, and that sodium sulfate, a valuable chemical for the pulp mill, is a side-product. These methanol-based processes provide high efficiency and can be made very safe.[13]

The variant process using chlorate, hydrogen peroxide and sulfuric acid has been increasingly used since 1999 for water treatment and other small-scale disinfection applications, since it produce a chlorine-free product at high efficiency.

Other processes

Very pure chlorine dioxide can also be produced by electrolysis of a chlorite solution:[19]

2 NaClO2 + 2 H2O → 2 ClO2 + 2 NaOH + H2

High-purity chlorine dioxide gas (7.7% in air or nitrogen) can be produced by the gas–solid method, which reacts dilute chlorine gas with solid sodium chlorite:[19]

2 NaClO2 + Cl2 → 2 ClO2 + 2 NaCl

Handling properties

At partial pressures above 10 kPa[13] (or gas-phase concentrations greater than 10% volume in air at STP), ClO2 may explosively decompose into chlorine and oxygen. The decomposition can be initiated by light, hot spots, chemical reaction, or pressure shock. Thus, chlorine dioxide gas is never handled in concentrated form, but is almost always handled as a dissolved gas in water in a concentration range of 0.5 to 10 grams per liter. Its solubility increases at lower temperatures, thus it is common to use chilled water (5 °C) when storing at concentrations above 3 grams per liter. In many countries, such as the United States, chlorine dioxide gas may not be transported at any concentration and is almost always produced at the application site using a chlorine dioxide generator.[13] In some countries,[which?] chlorine dioxide solutions below 3 grams per liter in concentration may be transported by land, however, they are relatively unstable and deteriorate quickly.

Uses

Chlorine dioxide is used for the bleaching of wood pulp, the treatment of drinking water (Chlorine dioxide is an oxidizer while other chlorine based disinfectants, such as bleach and chlorine, use a process called chlorination), treatment of water in oil & gas applications, disinfection in the food industry, Microbiological control in cooling towers, and textile bleaching.[20]

Bleaching

Chlorine dioxide is sometimes used for bleaching of wood pulp in combination with chlorine, but it is used alone in ECF (elemental chlorine-free) bleaching sequences. It is used at moderately acidic pH (3.5 to 6). The use of chlorine dioxide minimizes the amount of organochlorine compounds produced.[21] Chlorine dioxide (ECF technology) currently is the most important bleaching method worldwide. About 95% of all bleached kraft pulp is made using chlorine dioxide in ECF bleaching sequences.[22]

Chlorine dioxide has been used to bleach flour.[23]

Water treatment

Further information: Water chlorination and Portable water purification § Chlorine dioxide

The Niagara Falls, New York, water treatment plant first used chlorine dioxide for drinking water treatment in 1944 for destroying "taste and odor producing phenolic compounds".[24]: 4–17 [25] Chlorine dioxide was introduced as a drinking water disinfectant on a large scale in 1956, when Brussels, Belgium, changed from chlorine to chlorine dioxide.[25] Its most common use in water treatment is as a pre-oxidant prior to chlorination of drinking water to destroy natural water impurities that would otherwise produce trihalomethanes on exposure to free chlorine.[26][27][28] Trihalomethanes are suspect carcinogenic disinfection by-products[29] associated with chlorination of naturally occurring organics in the raw water.[28] Chlorine dioxide is also superior to chlorine when operating above pH 7,[24]: 4–33  in the presence of ammonia and amines[citation needed] and for the control of biofilms in water distribution systems.[28] Chlorine dioxide is used in many industrial water treatment applications as a biocide including cooling towers, process water, and food processing.[30]

Chlorine dioxide is less corrosive than chlorine and superior for the control of Legionella bacteria.[25][31] Chlorine dioxide is superior to some other secondary water disinfection methods in that chlorine dioxide is an EPA-registered biocide, is not negatively impacted by pH, does not lose efficacy over time (the bacteria will not grow resistant to it), and is not negatively impacted by silica and phosphates, which are commonly used potable water corrosion inhibitors.

It is more effective as a disinfectant than chlorine in most circumstances against waterborne pathogenic agents such as viruses,[32] bacteria and protozoa – including the cysts of Giardia and the oocysts of Cryptosporidium.[24]: 4-20–4-21 

The use of chlorine dioxide in water treatment leads to the formation of the by-product chlorite, which is currently limited to a maximum of 1 part per million in drinking water in the USA.[24]: 4–33  This EPA standard limits the use of chlorine dioxide in the US to relatively high-quality water because this minimizes chlorite concentration, or water that is to be treated with iron-based coagulants (iron can reduce chlorite to chloride).[citation needed]

Use in public crises

Chlorine dioxide has many applications as an oxidizer or disinfectant.[13] Chlorine dioxide can be used for air disinfection[33] and was the principal agent used in the decontamination of buildings in the United States after the 2001 anthrax attacks.[34] After the disaster of Hurricane Katrina in New Orleans, Louisiana, and the surrounding Gulf Coast, chlorine dioxide was used to eradicate dangerous mold from houses inundated by the flood water.[35]

In addressing the COVID-19 pandemic, the U.S. Environmental Protection Agency has posted a list of many disinfectants that meet its criteria for use in environmental measures against the causative coronavirus.[36][37] Some are based on sodium chlorite that is activated into chlorine dioxide, though differing formulations are used in each product. Many other products on the EPA list contain sodium hypochlorite, which is similar in name but should not be confused with sodium chlorite because they have very different modes of chemical action.

Other disinfection uses

Chlorine dioxide may be used as a fumigant treatment to "sanitize" fruits such as blueberries, raspberries, and strawberries that develop molds and yeast.[38]

Chlorine dioxide may be used to disinfect poultry by spraying or immersing it after slaughtering.[39]

Chlorine dioxide may be used for the disinfection of endoscopes, such as under the trade name Tristel.[40] It is also available in a trio consisting of a preceding pre-clean with surfactant and a succeeding rinse with deionized water and a low-level antioxidant.[41]

Chlorine dioxide may be used for control of zebra and quagga mussels in water intakes.[24]: 4–34 

Chlorine dioxide was shown to be effective in bedbug eradication.[42]

For water purification during camping, chlorine dioxide generating tablets disinfect more pathogens than household bleach, but at a higher cost per volume.[43][44]

Pseudomedicine

See also: Miracle Mineral Supplement

Chlorine dioxide is fraudulently marketed as a magic cure for a range of diseases from Brain cancer to HIV/AIDS. Enemas of chlorine dioxide are a supposed cure for childhood autism, resulting in complaints to the FDA reporting life-threatening reactions,[45] and even death.[46] Chlorine dioxide is relabeled to a variety of brand names including, but not limited to MMS, Miracle Mineral Solution and CD protocol.[47] There is no scientific basis for chlorine dioxide's medical properties and FDA has warned against its usage.[48][49]

Other uses

Chlorine dioxide is used as an oxidant for destroying phenols in wastewater streams and for odor control in the air scrubbers of animal byproduct (rendering) plants.[24]: 4–34  It is also available for use as a deodorant for cars and boats, in chlorine dioxide-generating packages that are activated by water and left in the boat or car overnight.

Safety issues in water and supplements

Chlorine dioxide is toxic, hence limits on exposure to it are needed to ensure its safe use. The United States Environmental Protection Agency has set a maximum level of 0.8 mg/L for chlorine dioxide in drinking water.[50] The Occupational Safety and Health Administration (OSHA), an agency of the United States Department of Labor, has set an 8-hour permissible exposure limit of 0.1 ppm in air (0.3 mg/m3) for people working with chlorine dioxide.[51]

On July 30, 2010, and again on October 1, 2010, the United States Food and Drug Administration warned against the use of the product "Miracle Mineral Supplement", or "MMS", which when prepared according to the instructions produces chlorine dioxide. MMS has been marketed as a treatment for a variety of conditions, including HIV, cancer, autism, and acne. The FDA warnings informed consumers that MMS can cause serious harm to health and stated that it has received numerous reports of nausea, diarrhea, severe vomiting, and life-threatening low blood pressure caused by dehydration.[52][53] This warning was repeated for a third time on 12 August 2019, and a fourth on April 8, 2020, stating that ingesting MMS is the same as drinking bleach, and urging consumers to not use them or give these products to their children for any reason.[49]
