Sodium chlorite CAS#7758-19-2
Good Water Solubility: Dissolves readily in water and alcohol, making it suitable for applications requiring an aqueous solution.
Stable Under Normal Storage Conditions: Remains relatively stable at room temperature when stored under appropriate conditions.
Alkaline Solution Properties: Typically appears as a white or slightly yellow-green aqueous solution with alkaline characteristics and slight hygroscopicity.
Reactive Chlorine Dioxide Precursor: Releases chlorine dioxide gas upon contact with acids, providing useful chemical reactivity for controlled industrial applications.
Products Description of Sodium Chlorite CAS#7758-19-2
Liquid sodium chlorite is an alkaline, slightly hygroscopic aqueous solution that typically appears white or pale yellow-green in color. It is readily soluble in water and alcohol and remains relatively stable at room temperature under normal storage conditions.
However, sodium chlorite can decompose and release chlorine dioxide gas when it comes into contact with acids. It may also present fire or explosion hazards when exposed to sawdust, organic materials, or reducing substances. As a toxic chemical, sodium chlorite requires careful handling, appropriate storage conditions, and strict adherence to relevant safety precautions.

Product Application of Sodium Chlorite CAS#7758-19-2
Sodium chlorite is an effective bleaching agent and oxidizing agent with a wide range of industrial applications. It is primarily used for bleaching pulp, paper, and various fibers, including cotton, hemp, reed, and viscose fibers. It can also be applied in the bleaching of sugar, flour, starch, grease, and wax.
In addition, sodium chlorite is used in leather hair removal processes, the surface treatment of certain metals, drinking water purification, and wastewater treatment. It can also serve as a discharge agent in indanthrene dyeing processes.
