  Ammonium oxalate (NH4)2C204, is a white solid soluble, formed by reaction of NH40H and oxalic acid, and then evaporating. Used as a source of oxalate; ammonium binoxalate NH4HC204·H20.

• 使用

  Ammonium oxalate monohydrate can be used to study chelators, biological buffers and biochemicals and reagents. It has been used for the detection and determination of calcium, lead, fluoride, and rare earth metals. It is employed as chelators and forms complexes with metals. It acts as reducing agent in gold extraction and is an active ingredient of ferrous metal surface polishing fluid. It is a promoting agent in production of cobalt oxide and nickel oxide. It has been used in an analysis of the effective segregation coefficient keff of different impurities, which suggested that the dehydration energies of cations mainly determine the capability of capture of impurity species by the growing crystal. It is widely utilized as a buffering reagent and a dispersant to determine the surface interaction of platelets. Ammonium oxalate monohydrate is also a buffering reagent and a dispersant to determine the surface interaction of platelets and to investigate the formation of oxalate monoalkylamide in the human lens. Ammonium oxalate monohydrate has also been used to study its acute poisoning effect on sheep, and surely has many additional uses.

• 一般的な説明

  Ammonium oxalate monohydrate is a diammonium salt of oxalic acid. Its refined crystal structure has been investigated by three-dimensional diffraction studies. Influence of bivalent [Mn(II), Co(II), Ni(II)] and trivalent cations [Fe(III), Cr(III)] impurities on the growth rates of ammonium oxalate monohydrate crystals has been described. Its space group and unit cell parameters have been analyzed by neutron diffraction studies. Its IR spectra have been compared with that of isolated coal-solubilizing agent (CSA).

• 職業ばく露

  It is used in chemical analysis and to make blueprint paper, explosives; a rust-removal ingredient in metal polishes.

• 輸送方法

  UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN1759 Corrosive solids, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required.

• 純化方法

  Crystallise it from water (10mL/g) at 50o. [Beilstein 2 IV 1846.]

• 不和合性

  Ammonium oxalate is a reducing agent and also reacts as a base to neutralize acids and reacts with oxidizers generating carbon dioxide. Incompatible with oxidizers (chlorates, hypochlorite solutions, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
