Oxalic acid's main applications include cleaning or bleaching, especially for the removal of rust (iron complexing agent). Its utility in rust removal agents is due to its forming a stable, water-soluble salt with ferric iron, ferrioxalate ion. Oxalic acid is an ingredient in some tooth whitening products.
Oxalate oxidase （Enzyme Commission number EC 1.2.3.4 [2] ）occurs mainly in plants. It can degrade oxalic acid into carbon dioxide and hydrogen peroxide. [3]Oxalate decarboxylase (OXDC，EC 4.1.1.2) is a kind of oxalate degrading enzyme containing Mn 2+, [4] found mainly in fungi or some bacteria.
It can also be prepared by treating oxalic acid with phosphorus pentachloride. [6] [7] Oxalyl chloride is produced commercially from ethylene carbonate. Photochlorination gives the perchloroethylene carbonate C 2 Cl 4 O 2 CO and hydrogen chloride HCl, which is subsequently degraded to oxalyl chloride and phosgene COCl 2: [8] C 2 H 4 O 2 CO + 4 ...
In enzymology, an oxalate oxidase (EC 1.2.3.4) is an oxalate degrading enzyme that catalyzes the chemical reaction: . oxalate + O 2 + 2 H + 2 CO 2 + H 2 O 2. The 3 substrates of this enzyme are oxalate, O 2, and H +, whereas its two products are CO 2 and H 2 O 2.
Cerium(III) oxalate (cerous oxalate) is the inorganic cerium salt of oxalic acid. It is a white crystalline solid with the chemical formula of Ce 2 (C 2 O 4 ) 3 . It could be obtained by the reaction of oxalic acid with cerium(III) chloride .
For example, diethyl oxalate condenses with cyclohexanone to give the diketo-ester, a precursor to pimelic acid. [8] With diamines, the diesters of oxalic acid condense to give cyclic diamides. Quinoxalinedione is produced by condensation of dimethyloxalate and o-phenylenediamine: C 2 O 2 (OMe) 2 + C 6 H 4 (NH 2) 2 → C 6 H 4 (NHCO) 2 + 2 MeOH
4) is a silver salt of oxalic acid commonly employed in experimental petrology to add carbon dioxide (CO 2) to experiments as it will break down to silver (Ag) and carbon dioxide under geologic conditions. [2] It is also a precursor to the production of silver nanoparticles. It is explosive upon heating around 140 degrees Celsius, shock or ...
Neptunium (IV) oxalate [1] is an inorganic compound, a salt of neptunium and oxalic acid with the chemical formula Np(C 2 O 4) 2. [2] The compound is slightly soluble in water, forms crystalline hydrates—green crystals.
