Green to blue powder
The Uses of Praseodymium chloride
Praseodymium(III) chloride is used in producing metal praseodymium and praseodymium compounds,glass,ceramic and coloring.
Safety Profile
Poison by intraperitoneal, subcutaneous, and intravenous routes. Moderately toxic by ingestion. A skin and eye irritant. When heated to decomposition it emits toxic fumes of Cl-. See also PRASEODYMIUM.
Purification Methods
Its 1M solution in 6M HCl is passed twice through a Dowex-1 anion-exchange column. The eluate is evaporated in a vacuum desiccator to about half its volume and allowed to crystallise [Katzin & Gulyas J Phys Chem 66 494 1962].
