Properties:
Propylphosphonic anhydride is a colorless to light yellow propylphosphonate compound with the chemical formula C9H21O6P3. It is a water-soluble compound that can dissolve in water to form a solution. It is a liquid at room temperature and has a pungent odor.
Uses:
Propylphosphonic anhydride is commonly used as a corrosion inhibitor, flame retardant, and additive in metalworking fluids in industrial production. It is also used in the field of biomedicine.
Synthesis:
Propylphosphonic anhydride can be synthesized by the reaction of phosphorus oxychloride with propylene glycol.
Safety:
Propylphosphonic anhydride has relatively high safety, but precautions should still be taken. Contact with skin or inhalation of high concentrations of propylphosphonic anhydride can cause irritation and discomfort, so prolonged exposure should be avoided. Proper protective equipment should be worn during use, and the environment should be well-ventilated. Risks to human health and the environment can be minimized through correct operation and storage methods.
