Application

 

Sodium chlorite is used in the in situ generation of chlorine dioxide for stripping of textiles, bleaching, pulp and paper industries. It acts as a disinfectant in water treatment plant and as a preservative in eye drops. It is also used in contact lens cleaning solution and for sanitizing air ducts. It is associated with zinc chloride and used as a component in therapeutic rinses, toothpastes, mouth sprays and gels. It is utilized for the synthesis of 4-oxo-2-alkenoic acids from alkyl furans. Further, it is involved as a reagent in Pinnick oxidation reaction to prepare carboxylic acid from aldehydes.
