Industrial Uses

1. Agrochemicals

  • Nitrogen source: Ammonium chloride is a readily available source of nitrogen, a crucial nutrient for plant growth and development.
  • Soil acidification: Ammonium chloride can contribute to soil acidification due to the physiological acidity of the fertilizer.

2. Metal treatment

  • Galvanizing: Ammonium chloride is a crucial electrolyte in the hot-dip galvanizing process, which creates a protective zinc coating on steel. It also helps remove oxide coatings from metal surfaces, ensuring a clean surface for galvanizing.
  • Fluxing: Ammonium chloride is used as a flux to help clean and prepare metal surfaces before soldering, tin coating, or galvanizing.
  • Colorants: Some of its products are used as colorants in enamels and porcelain ware.

3. Fabric solutions

  • Mordant: Ammonium chloride helps dyes adhere more effectively to fabrics by influencing the pH of the dye solution, which in turn affects the interaction between dye molecules and fabric fibers.
  • Dye Fixation and Stabilization: It can enhance the fixation of dyes on fibers, improving color fastness, and also stabilizes dyes by preventing oxidation or hydrolysis.

4. Personal care

  • Thickening Agent: Ammonium chloride helps increase the viscosity of personal care products, making them more concentrated and improving their texture. 
  • Improved Lather: It can enhance the lather of products like shampoos and body washes, providing a richer and more satisfying cleansing experience. 
  • Moisture Absorption: Ammonium chloride can absorb moisture, which can contribute to a thicker product and a more viscous feel. 

5. Animal Healthcare

  • Regulating Acidity: Ammonium chloride is used as an acidity regulator in feed for various species, including bovines, sheep, dogs, and cats. By acidifying the urine, ammonium chloride helps prevent the formation of urinary stones, which can be a significant problem in livestock.

6. Performance Chemicals

  • Catalyst: Ammonium chloride is a versatile catalyst, especially for reactions involving acidic conditions or when ammonia is needed as a reactant or solvent.
  • Reduction: It aids in the reduction of azo compounds to hydrazines and nitro phenols.
  • Synthesis: It's used in the synthesis of various heterocyclic compounds, including imidazoles, pyrroles, pyridines, and dihydropyrimidinones.
