Chlorine dioxide Usage And Synthesis
  1. Chlorine dioxide has a variety of commercial uses. In all of the following applications, sodium chlorite is used in the generation of the chlorine dioxide.
  2. Treatment of Potable Water. Chlorine dioxide has long been used to remove tastes and odors in potable water. It is also used in the disinfection of water, particularly where trihalomethanes are of concern. Chlorine dioxide also oxidizes soluble manganese and iron compounds, eliminating a major cause of stained sinks and fixtures.
  3. Bacterial Control in Oil Wells and Petroleum Systems. A patented use for chlorine dioxide is to treat water that is or will be contaminated with petroleum oil. Many such mixtures contain sulfitereducing bacteria that form undesirable sulfide compounds. Chlorine dioxide oxidizes these sulfides to sulfates, while preventing or substantially retarding the formation of colloidal sulfur.
  4. Bacterial Slime Control in Paper Mills. Some of the major operational problems in paper and paperboard production are caused by proliferation of microbiological organisms in white water and stock systems. As an oxidizing biocide, chlorine dioxide, can control microbiological growths, which cause paper malodors and discoloration, deterioration of felts, equipment corrosion, fouling of pipes and showers, and paper quality problems such as spots, specks and holes.
  5. Food Processing. Chlorine Dioxide is highly effective for microbiological control in organically contaminated flume waters. Control of microbiological growths is necessary to ensure food product safety and quality. Chlorine dioxide has also found an application in cherry bleaching.
  6. Algae Control in Cooling Towers. Chlorine dioxide efficiently and economically controls microbiological growths in industrial cooling waters under conditions unfavorable to chlorine. It is the primary microbiological control agent in systems with high pH, ammonia-nitrogen contamination, or persistent slime problems.
  7. Treatment of Wastes. Chlorine dioxide is used to disinfect sewage and plant wastes. It destroys phenolics, simple cyanides and sulfides by oxidation.
  8. Stripping Dyestuffs from Textiles. Chlorine dioxide removes dyestuffs from textiles with a minimum of fiber degradation. However, its effectiveness depends upon the dyestuff and the type of fabric. This method also provides a good bottom for redying.
  9. Upgrading of Fats and Oils. Chlorine dioxide is effective in the bleaching of fats and oils. The process is simple and low cost and since it eliminates the need for a filter medium, it produces a higher yield than other methods. (About 30% of the weight of the filter residue, which is generally discarded, is tallow.) Problems such as storage and handling of the filter medium and disposal of filter residues are eliminated as well.
Chemical PropertiesChlorine dioxide,CI02, is a yellow-reddish gas.It is a very effective bleaching and water treatment agent. Chlorine dioxide is preparedby the reaction of chlorine and sodium chlorite. It is quite unstable and is commonly prepared immediately before use.
Chemical PropertiesChlorine dioxide is a flammable, reddishyellow gas, or reddish-brown liquid (below 11C/52F) with an irritating odor like chlorine or nitric acid.
UsesChlorine Dioxide is a gas used in bleaching and aging flour. it acts on the flour almost instantly, resulting in improved color and dough properties. because usage levels are low, the bleaching action is limited.
UsesBleaching cellulose, paper-pulp, flour, leather, fats and oils, textiles, beeswax; purification of water; taste and odor control of water; cleaning and detanning leather; manufacture of chlorite salts; oxidizing agent; bactericide, antiseptic and deodorizer.
HazardExplodes when heated or by reaction with organic materials. Very irritating to skin and mucous membranes. Lower respiratory tract irritant. Broncitis.
Safety ProfileModerately toxic by inhalation. Experimental reproductive effects. Mutation data reported. An eye irritant. A powerful explosive sensitive to spark, impact, sunlight, or heating rapidly to 100℃. A powerful oxidzer. Concentrations of greater than 10% in air are explosive. Explodes on mixing with carbon monoxide, hydrocarbons (e.g., butadiene, ethane, ethylene, methane, propane), fluoramines (e.g., difluoramine, trifluoramine). Mtxtures with hydrogen explode with sparking or contact with platinum. Explodes on contact with mercury, potassium hydroxide, phosphorus pentachloride + chlorine. Ignites or explodes on contact with nonmetals (e.g., phosphorus, sulfur, sugar). Reacts violently with F2, NHF2. Reacts with water or steam to produce toxic and corrosive fumes of HCl. When heated to decomposition it emits toxic fumes of Cl-. See also CHLORINE.
Potential ExposureChlorine dioxide is used in bleaching cellulose pulp; bleaching flour; water purification; as a liquid sterilizer in an ultrasonic cleaner.
First aidIf this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
ShippingUN/NA 9191 Chlorine dioxide, hydrate, frozen, Hazard class: 5.1; Labels: 5.1-Oxidizer, 6.1-Poison Inhalation. Explosive: It may only be shipped in the frozen state and then only by private or contract motor carrier.
IncompatibilitiesUnstable in light. A powerful oxidizer. Chlorine dioxide gas is explosive at concentrations over 10% and can be ignited by almost any form of energy, including sunlight, heat (explosions can occur in air in temperature above 130C), or sparks, shock, friction, or concussion. This chemical reacts violently with dust, combustible materials; and reducing agents. Reacts violently with mercury, phosphorus, sulfur, and many compounds, causing fire and explosion hazard. Contact with water forms perchloric and hydrochloric acid. Corrosive to metals.
Waste DisposalUse large volume of concentrated solution of ferrous salt or bisulfite solution as reducing agent. Then neutralize and flush to sewer with abundant water.
