Description
Sodium thiosulfate (Na₂S₂O₃) is an inorganic compound commonly encountered as the white or colorless pentahydrate (Na₂S₂O₃·5H₂O). It readily dissolves in water and exhibits intriguing properties as both a reducing agent and a ligand.
Application
1.Used as a dechlorination agent for bleached pulp and cotton fabrics, as a chelating agent and antioxidant in the food industry, as a detergent and disinfectant in the pharmaceutical industry.
2.It is used for dehydrochlorination of natural gas, naphtha, syngas, hydrogen and nitrogen to protect downstream catalyst from toxicity. If there is organic chlorine in the gas, it should be converted to hydrogen chloride by cobalt-molybdenum hydrogenation catalyst, and then absorbed with dechlorinating agent.
3.Used as analytical reagent, mordant and fixative.
4.It is suitable for removing chlorine from hydrogen, nitrogen, syngas, Carbon monoxide, carbon dioxide and naphtha.
5.Photosensitive industry is used as photographic fixative. Paper industry is used as chlorine removal agent after pulp bleaching. The printing and dyeing industry is used as a dechlorination agent for cotton fabrics after bleaching. Reagent for chroma analysis and volumetric analysis of analytical chemistry. Pharmaceuticals are used as detergents and disinfectants. The food industry is used as chelating agents, antioxidants and so on.
7.It is used in Photography, film, textile, chemical fiber, paper making, leather making and pesticide industry.
8.Used as complexing agent for silver plating of thiosulfate. The silver plating layer has fine crystal structure and good covering ability. The general dosage is 200~250 g/L. It is used as brightener in cyanide silver plating. The dosage is 0.5 to 1.09 g/L. Silver can be crystallized in order to obtain bright and semi bright silver plating.
