Sodium hypochlorite - Upstream Downstream Industry
Sodium hypochlorite - Nature
Open Data Verified Data
sodium hypochlorite is a white powder. Industrial sodium hypochlorite is a colorless or yellowish liquid. Melting Point 18 °c. Very unstable in air, decomposition to produce carbon dioxide. It decomposes rapidly after heating and is stable in alkaline state. Sodium hypochlorite is easily soluble in water, and is dissolved in water to form caustic soda and hypochlorous acid. lOOmL HzO dissolves 29.3g sodium hypochlorite at 0 ℃. Hypochlorous acid is decomposed to generate hydrogen chloride and new oxygen. The oxidation ability of new oxygen is very strong, so sodium hypochlorite is also a strong oxidant. Its stability is affected by light, heat, heavy metal cations and Ph. Irritating odor.

Sodium hypochlorite - Preparation Method
Open Data Verified Data
There are many methods for preparing sodium hypochlorite, and the method commonly used in industry is liquid alkali chlorination. Add a certain amount of liquid alkali, add an appropriate amount of water, prepare a sodium hydroxide solution of less than 30%, and pass chlorine gas below 35 ℃ for reaction. When the content of sodium hypochlorite in the reaction solution reaches a certain concentration, the sodium hypochlorite product was obtained.

Sodium hypochlorite - Use
Open Data Verified Data
is an oxidizing bactericide, and its bactericidal mechanism is similar to that of liquid chlorine. Sodium hypochlorite solution is generally used in industrial circulating water. At the same time, sodium hypochlorite increased the pH value of the circulating water. Therefore, in the circulating water system with liquid chlorine as bactericide, the residual chlorine is difficult to reach the target. In the case of serious decrease of pH value, a large dose of sodium hypochlorite is used for shock dosing, the indicators of residual chlorine and pH can be ensured.

Sodium hypochlorite - Safety
Open Data Verified Data
mouse oral LDso:8500mg/kg. It has strong oxidation and corrosion. Skin contact can cause burns. Entering the body will lead to mucosal erosion, esophageal or tracheal perforation, throat edema. Inhalation into the lungs causes severe burns to the bronchi and edema in the lungs. Contact and use of staff should be well protected to prevent ammonium hypochlorite solution into the human body and skin.
