AMMONIUM BISULPHITE

Ammonium bisulphite is a clear, colorless to pale yellow aqueous solution with a pungent sulfur dioxide odor. It acts as a powerful reducing agent and oxygen scavenger. Major applications include bleaching in pulp and paper mills, dechlorination in wastewater treatment, photographic fixing, textile processing, and as a preservative in food and beverages. It is also employed in organic chemical synthesis. This product is corrosive and may release toxic SO₂ fumes; use adequate ventilation and protective equipment.

  • Pharmaceutical reducing agent
  • Dye & pesticide synthesis
The main detailed uses of the product
  • Water-based Coating Formulations
    Water-based Coating Formulations

    Serves as a key monomer in water-based industrial and architectural coatings, imparting good gloss and stain resistance.

  • Water Treatment Clarification
    Water Treatment Clarification

    Acts as an effective organic coagulant and flocculant in water treatment processes. Its cationic charge neutralizes negatively charged colloidal particles, causing them to clump together for easy removal, thereby clarifying water.

  • Agrochemical Emulsifiers
    Agrochemical Emulsifiers

    Used in the synthesis of emulsifiers for pesticide and herbicide formulations, helping to stabilize oil-in-water emulsions and enhance the effectiveness of active ingredients.

  • Chemical Synthesis
    Chemical Synthesis

    Used as a catalyst and intermediate in various organic synthesis reactions, particularly in Friedel-Crafts reactions and as a stabilizer for peroxides.

Why Choose Our AMMONIUM BISULPHITE ?

1.High-Purity Reducing Agent: Offers exceptional reducing capacity and oxygen-scavenging properties, effectively preventing oxidative degradation and color darkening in chemical synthesis and photographic fixers.

2.Superior pH Buffering & FGD Performance: Provides precise pH control in industrial wastewater treatment and acts as an efficient absorbent in flue gas desulfurization (FGD) systems, removing up to 99% of SO₂ emissions.

3.Excellent Solubility & Reaction Kinetics: Features high water-solubility across a wide temperature range, ensuring rapid dissolution, consistent dosing accuracy, and instantaneous chemical reactions in continuous processes.

4.Corrosion Inhibition Properties: When applied in oilfield waterflooding and refinery overhead systems, it forms protective films that effectively neutralize caustic cracking and mitigate chloride-induced corrosion.

5.Cost-Effective Bulk Supply: Stable, non-hazardous crystalline form allows for safe, cost-efficient bulk storage and transportation, reducing logistics costs while maintaining a long shelf-life under proper conditions.
