Main Applications:

1. Textile and Dyeing Industry:
   • Reduction Dyes: Rongalite is commonly used in the dyeing process of reduction dyes, especially for the reduction and dyeing of disperse dyes.
   • De-colorizing: It can also serve as a decolorizing agent in textiles, removing or lightening color from fabrics.
2. Chemical Reduction Reactions:
   • Rongalite is often used as a reducing agent in chemical synthesis, particularly in the reduction of aldehydes, nitro compounds, and other similar compounds.
   • It is also used in some metal surface treatments and catalyst synthesis to reduce metal ions.
3. Pulp and Paper Industry:
   • In the paper bleaching process, Rongalite is used as a reducing agent to remove certain oxidized compounds, thereby improving the whiteness of paper.
4. Pharmaceutical and Cosmetics Industries:
   • Reduction Reactions: Rongalite is used in some pharmaceutical synthesis reactions, especially for the reduction of certain chemicals that require reduction for production.
5. Environmental Protection:
   • Wastewater Treatment: Rongalite is used in the treatment of wastewater containing heavy metals, as it can reduce metal ions and help remove pollutants from water.
