Description and Uses

Oxalic acid is a colorless, odorless powder orgranular solid. The anhydrous form (COOH)2 is an odorless,white solid; the solution is a colorless liquid. Molecularweight = 90.04; Specific gravity (H2O:1) = 1.90; Sublimationpoint =150-157℃; Freezing/Melting point (decomposes):101.7℃; 190℃ (anhydrous). Hazard Identification (based onNFPA-704 M Rating System): Health 3, Flammability 1,Reactivity 0. Moderately soluble in water.

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.
