SAMARIUM NITRATE HEXAHYDRATE

Samarium (III) nitrate hexahydrate is a yellow to tan powder and chunks in physical appearance and is an oxidiser. It has application as a chemical reagent. It is hygroscopic – absorbs moisture from the air.

Samarium(III) nitrate hydrate is used as a catalyst in von Pechmann condensation for the preparation of coumarins. Further, it finds use in optical glasses, structural ceramics, catalysts, electrical components and photo-optical material. It is also used as a laboratory reagent. In addition to this, it is used in NMR spectroscopy for spectral resolution and is used for doping purposes.

Samarium(III) nitrate hexahydrate is a Lewis acid catalyst that is used in the synthesis of a variety of materials for applications such as:

• synthesis of nitrate precursor solution which can be used as a nanocatalyst in the solid oxide regenerative fuel cells.
• for the formation of coumarin derivative by von Pechmann condensation of phenol with ethyl acetoacetate in the presence of samarium complex as catalyst.
• for the preparation of samarium doped ceria, which can be used in the fabrication of electrolyte for fuel cells.
