Applications
Pesticide Industry: It is an important intermediate for producing various pesticides, such as the production of glyphosate herbicides. Glyphosate is a widely used non-selective herbicide, and phosphorous acid plays a crucial role in its synthesis process, improving the synthesis efficiency and product quality of glyphosate.
Water Treatment Field: It can be used as a water treatment agent to remove heavy metal ions from water, such as forming insoluble phosphate precipitates with iron ions and copper ions in water, thus purifying water quality. It can also act as a corrosion inhibitor to prevent the corrosion of metal equipment by dissolved oxygen in water.
Chemical Plating Industry: In the nickel electroplating process, phosphorous acid is commonly used as a reducing agent. It can reduce nickel ions to metallic nickel, forming a uniform and dense nickel-phosphorus alloy plating layer on the metal surface, enhancing the corrosion resistance, wear resistance, and conductivity of the metal.
Pharmaceutical Field: It can be used to synthesize some pharmaceutical intermediates, which can then be used to produce antibiotics, vitamins, and other drugs. For example, in the synthesis process of certain antibiotics, phosphorous acid participates in specific reaction steps, helping to build the molecular structure of the drug and enhance its activity and stability.
Other Fields: Phosphorous acid can also be used to produce phosphites, such as potassium phosphite, sodium phosphite, etc. These phosphites can be used as fertilizers in agriculture to provide phosphorus to plants and have certain fungicidal effects. In the plastics industry, phosphorous acid can be used as an antioxidant to prevent oxidation degradation of plastics during processing and usage, extending the service life of plastics.
Safety Precautions
Phosphorous acid is corrosive and can irritate the skin, eyes, and respiratory tract. Contact with skin can cause burns, so protective goggles, gloves, and clothing should be worn when handling. If accidentally exposed to skin or eyes, rinse with plenty of water and seek medical attention.
Store in a sealed container in a cool, ventilated warehouse, away from ignition sources, heat sources, oxidizers, alkalis, and other substances to prevent chemical reactions.
During transportation, ensure the packaging is intact to prevent leaks. Transport vehicles should be equipped with appropriate firefighting equipment and emergency response devices for leaks. Transportation personnel should be familiar with the nature of phosphorous acid and safety precautions, and comply with relevant transportation regulations.
