Stable chlorine dioxide - Names and Identifiers
Stable chlorine dioxide - Physico-chemical Properties
Molecular Formula | ClO2
|
Physical and Chemical Properties | Yellow-green gas, compressed into colorless or light yellow transparent liquid, no suspended matter, unpleasant smell. Melting point -59 ℃, boiling point 11 ℃. Soluble in glacial acetic acid and carbon tetrachloride, slightly soluble in water (0.3g/100mL). When exposed to light, it will decompose into oxygen and chlorine, causing an explosion. The oral LD50 of rats was greater than 2.5 g/kg and ADI 0-15mg/kg(FAO/WHO,1994). |
Stable chlorine dioxide - Introduction
Stable chlorine dioxide (ClO2) is a colorless gas with a peculiar pungent odor. The following is a description of the properties, uses, methods and safety information of stable chlorine dioxide:
Nature:
1. Stable chlorine dioxide is a strong oxidant, can react with many organic and inorganic substances.
2. It has high solubility and is converted into hypochlorous acid and chlorate ions in water.
3. Its oxidation ability than bleaching powder and chlorine, at low concentrations can also effectively sterilization, disinfection and oxidation to remove odor.
4. The two oxygen atoms in its molecule form a constraint on chlorine dioxide, making it more stable.
Use:
1. Stable chlorine dioxide is widely used in the water treatment industry for killing bacteria, viruses, fungi and algae, removing odors and wastewater treatment.
2. It is also used in sanitary cleaning products and disinfectants for cleaning pools, swimming pools, drinking water and food processing equipment.
3. In the medical field, stable chlorine dioxide is used for disinfection and aseptic treatment.
Preparation Method:
1. Stable chlorine dioxide can be prepared by mixing chlorine and sodium hypochlorite.
2. The preparation process needs to control the reaction conditions and concentration to avoid the production of dangerous substances such as chlorine.
Safety Information:
1. Stable chlorine dioxide has a pungent odor and toxicity, and exposure to high concentrations of gas or liquid may cause irritation to the respiratory tract and eyes.
2. During use, attention should be paid to protective measures, such as wearing appropriate respirators and protective glasses.
3. Avoid contact with combustibles, acids and reducing agents to avoid accidents.
4. In the process of storage and handling, the relevant safety operation procedures should be strictly observed to avoid leakage and leakage.
5. Stable chlorine dioxide should be kept away from children and fire, stored in a dry, cool, ventilated place.
