Ammonium oxalate monohydrate Usage And Synthesis

Chemical Properties

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.

Chemical Properties

Ammonium oxalate is an odorless, colorless crystalline material or powder.

Uses

Used for the detection of calcium, lead, fluoride and a buffering agent

Uses

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.

Potential Exposure

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

Shipping

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.

Purification Methods

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

Incompatibilities

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.
