General description

Potassium titanium oxide oxalate dihydrate is used as a catalyst in organic synthesis because of its excellent water solubility. It can be easily separated from the reaction mixture after the completion of the reaction.

Application

Potassium titanium oxide oxalate (PTO) dihydrate can be used as:
  • A catalyst to synthesize chromene derivatives via three-component condensation reaction of aromatic aldehydes, malononitrile, and resorcinol/ naphthol.
  • An electrolyte to functionalize the surface of aluminum alloy with TiO2 layer by plasma electrolytic oxidation (PEO).

PTO can be used as a precursor to synthesize titanium dioxide (TiO2) nanoparticles.
