Uses and synthesis of Sodium dithionite powder

Sodium dithionite powder, commonly known as insurance powder, is a strong reducing agent, there are two forms of diaqueous salt and anhydrous salt. Sodium dithionite CAS 7775-14-6 is a white free-flowing crystalline powder with no odor or slightly sulfur dioxide odor. Sodium dithionite Raw Materials are mainly used as reducing agents for printing and dyeing, bleaching agents for pulp, linen, oil, etc., and for pharmaceutical and analytical reagents

Applications/Functions of Sodium dithionite powder

• Sodium dithionite powder is mainly used as a reducing agent for printing and dyeing, as a bleaching agent for pulp, linen and oil, and for pharmaceutical and analytical reagents
• Sodium dithionite CAS 7775-14-6 is used as a dyeing aid for cotton fabrics and as a bleach agent for cotton and woolen fabrics. Also used in medicine, mineral processing, copper plate printing, thiourea and other sulfide synthesis. Paper industry is also used as bleach, food grade products used as bleach, preservatives, antioxidants.
• Sodium dithionite Raw Materials are strong reducing agents that can reduce many metal salts into metals.
• It is used analytically as an oxygen absorber, and also as a dye intermediate and bleach agent

Physicochemical Property of Sodium dithionite powder

White crystalline powder. Highly soluble in water, insoluble in alcohol.

Production methodprocess of Sodium dithionite powder

After the reactants were removed from zinc hydroxide precipitate by press filtration (recovered to produce zinc oxide), Sodium chloride was added to the filtrate and cooled to 20℃ to crystallize sodium hyposulfite. After the crystals were filtered out, Sodium dithionite powder was obtained by dehydration and drying with alcohol.
