Ferric ammonium oxalate trihydrate Usage And Synthesis

Chemical Properties

yellow-green crystals

Chemical Properties

Ferric ammonium oxalate is a green crystalline, solid with a granular or salt-like appearance. Color depends on level of iron present

Uses

Ammonium iron(III) oxalate trihydrate is used in the preparation of Langmuir-Blodgett magnetic thin films. It is also involved in the production of blueprint paper.

General Description

Ammonium ferric oxalate trihydrate decomposes completely at 275°C giving Fe2O3 and has been investigated by thermogravimetry and differential thermal analysis.

Potential Exposure

Ferric ammonium oxalate is used in photography and making blueprints

Shipping

UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

Purification Methods

Crystallise it from hot water (0.5mL/g). [Beilstein 3 III 1103.]

Incompatibilities

Incompatible with oxidizers (chlorates, 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. Strong oxidizers may cause release of toxic phosphorus oxides. Organophosphates, in the presence of strong reducing agents such as hydrides, may form highly toxic and flammable phosphine gas. Keep away from alkaline materials.
