Oxalic acid technical

TU 2431-002-77057039-06
25 kg


Oxalic acid technical (ethanedioic acid) obtained by the oxidation of ethylene glycol with a mixture of nitric and sulfuric acids in the presence of a catalyst of vanadium pentoxide (V2O5).


Oxalic acid is used in the chemical and pharmaceutical industry, as a mordant in the textile and leather industries, as a component of the anodic film deposition baths for Al, Ti and Sn; as a reagent in analytical chemistry in organic synthesis, a component of metal cleaning rust, scale and oxides, for the deposition of REE, in microscopy as a bleach cuts.

Oxalic acid is colorless crystals.

Safety requirements

Oxalic acid technical- a combustible material in the settled state of oxalic acid dust fire hazard, the degree of impact on the body of the substances 2-hazard class. Oxalic Acid is a combustible solid below 101 ºC (215 °F) Explosion: Reacts explosively with strong oxidizing materials and some silver compounds.


Oxalic acid technical is packed in polyethylene bags with net weight (40.0 ± 0.5) or (25.0 ± 0.5) kg, bags made of polyethylene film with color printing, plywood reels of film bag inside, special soft disposable containers.

Guaranteed shelf life

6 months from date of manufacture.
