Vanadyl Oxalate(CAS#15500-04-6 ） introduction
Vanadium oxalate is an inorganic compound. The following is an introduction to the properties, uses, preparation methods and safety information of vanadium oxalate:
Quality:
- Vanadium oxalate is a dark red solid that is soluble in water and acidic solutions, but insoluble in non-polar solvents such as ethanol and ether.
- It has strong reducing and oxidizing properties and can act as an oxidizing agent or reducing agent in chemical reactions.
Use:
- Oxalate vanadium oxide is often used as a catalyst or mordant in chemical laboratories.
Method:
There are two main preparation methods for vanadium oxalate:
By the reaction of sodium vanadate and oxalic acid in aqueous solution, it is obtained:
Na3VO4 + 3H2C2O4 → VO(OH)(C2O4) + 3NaHC2O4 + 2H2O
By the reaction of vanadium oxide and oxalic acid in an acidic solution, the following results are obtained:
V2O5 + 4H2C2O4 + 2H2O → 2VO(OH)(C2O4) + 4H2O
Safety Information:
- Inhalation of dust or solutions of vanadium oxalate may cause respiratory irritation and should be operated in a well-ventilated area.
- Care should be taken to avoid contact with ignition sources or oxidants when storing and handling vanadium oxalate to prevent fire or explosion.
Application
Vanadyl oxalate (CAS 15500-04-6) is an advanced vanadium-based coordination compound widely employed as a versatile precursor and catalyst in high-tech industries. It serves as an efficient oxidation catalyst for the selective conversion of α-hydroxy esters to α-keto esters using molecular oxygen. In the energy sector, it is a critical raw material for synthesizing lithium vanadium phosphate (Li₃V₂(PO₄)₃) cathode material and formulating vanadium redox flow battery (VRFB) electrolytes, enhancing electrochemical performance, cycling stability, and energy density for large-scale grid storage. As a corrosion inhibitor, it forms protective films on hot-dip galvanized steel, effectively preventing galvanic corrosion. It also acts as a thermal decomposition precursor for preparing high-purity vanadium pentoxide (V₂O₅), nanostructured vanadium oxides for supercapacitors, and monolayer vanadia catalysts for selective catalytic reduction (SCR) of NOx emissions. Additionally, vanadyl oxalate shows potential as an insulin-mimetic agent for diabetes research, demonstrating antioxidant properties and improved glycemic control in biological studies.
