설명

일반 설명

Oxalic acid is present as potential impurity in some active pharmaceutical ingredients.

애플리케이션

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
