General description
Oxalic acid is present as potential impurity in some active pharmaceutical ingredients.
Application
Oxalic acid may be used as a catalyst to synthesize:
- 2-aryl-1-arylmethyl-1H-benzimidazoles from o-phenylenediamine and aldehydes
- 2-aryl-4,5-diphenyl-1H-imidazoles from benzyl/benzoin, ammonium acetate and aromatic aldehydes
- bis-compounds of indole and 2-naphthol in an aqueous medium
Oxalic acid was used:
- in the synthesis of hemicellulose hydrolysates of yellow poplars
- in the synthesis of three-dimensionally ordered macroporous metal oxides or carbonates via templating with polystyrene spheres
- as supporting electrolyte in the electrochemical synthesis of polyaniline-polypyrrole composite coatings
