Primary Applications of Phosphorous Acid
Phosphorous Acid's strong reducing capabilities, chelating properties, and versatile reactivity make it a fundamental chemical with extensive applications across various industries:
Production of Phosphite Salts:
The primary use of Phosphorous Acid is in the manufacturing of various phosphite salts (e.g., sodium phosphite, potassium phosphite, calcium phosphite). These phosphites are widely used as stabilizers for plastics (PVC), flame retardants, and in agricultural applications.
Water Treatment Chemicals:
It is used in the synthesis of water treatment chemicals, particularly phosphonates, which act as scale inhibitors, corrosion inhibitors, and dispersants in industrial water systems and cooling towers, preventing mineral buildup.
Reducing Agent:
As a powerful reducing agent, it is employed in various chemical processes to reduce other compounds. For example, it can reduce noble metal salts to their elemental forms.
Agriculture & Plant Health:
Phosphorous acid and its phosphite derivatives are used in agriculture as fungicides and plant defense activators. They enhance plants' natural resistance to various fungal and oomycete diseases, such as downy mildew and Phytophthora. They also act as a source of phosphorus nutrition.
Organic Synthesis Intermediate:
It serves as a key intermediate in organic synthesis for the production of various phosphorus-containing organic compounds, including pharmaceuticals, agrochemicals, and specialty chemicals.
Chelating Agent:
Its ability to form stable complexes with metal ions makes it useful as a chelating agent in certain industrial applications.

We utilize various UN (United Nations) certified packaging containers based on the chemical nature, hazard class, and transportation requirements of our products. Common packaging types include, but are not limited to: Steel Drums: Suitable for a wide range of liquid and solid products, especially flammable liquids. Plastic Drums/Jerricans: Primarily used for corrosive liquids like acids and bases, or substances incompatible with metal. Composite Drums: Combine the corrosion resistance of a plastic inner liner with the strength of a steel or fiber outer shell. IBCs (Intermediate Bulk Containers): Often referred to as "Tote Bins" or "Cubic Tanks," these are used for larger volumes of liquid or solid dangerous goods, offering efficient storage and transport solutions. Lined Bags or Fibre Drums: Primarily used for powdered or granular solids. Glass Bottles: Typically used as inner packaging for small quantities of high-purity or specialized chemicals, requiring additional absorbent material and sturdy outer packaging (e.g., wooden crates, fiberboard boxes). Steel Cylinders: Specifically designed and constructed as pressure vessels for the storage and transport of compressed, liquefied, or dissolved gases. Available in various capacities and pressure ratings, they are built to withstand high internal pressures and ensure the safe containment of gaseous substances.

| Proper storage is crucial for maintaining product quality and ensuring operational safety. The following are general storage principles: Dedicated Areas: Dangerous chemicals should be stored in designated warehouses or areas that meet safety standards, away from residential zones and densely populated areas. Segregated Storage: Strictly classify and segregate products according to their hazard class to prevent incompatible substances from being stored together and causing dangerous reactions (e.g., acids and bases separated, flammables away from oxidizers). Good Ventilation: Storage areas should maintain good natural or forced ventilation to prevent the accumulation of hazardous gases or vapors. Temperature & Humidity Control: Control the temperature and humidity of the storage environment according to the recommendations in the SDS. Avoid direct sunlight and extreme temperatures. Fire and Explosion Prevention: Storage areas for flammable and explosive products should be equipped with adequate fire-fighting equipment, prohibit open flames, and ensure electrical equipment meets explosion-proof standards. Clear Labeling: All storage containers and areas should have clear, conspicuous hazard labels and warning signs. Spill Response: Storage areas should be equipped with appropriate spill response equipment and materials, and personnel should be familiar with emergency procedures. Regular Inspections: Periodically inspect the integrity of storage containers to ensure no leaks or damage, and verify label information. Away from Food and Drinking Water: Avoid cross-contamination.
