POTASSIUM OXALATE MONOHYDRATE 99% A.C.S. REAGENT (C005B-055409)

General description

Potassium oxalate monohydrate (POM) is a potassium salt of oxalic acid. Its crystal structure has been investigated by three-dimensional neutron diffraction studies.

Application

Potassium oxalate monohydrate may be used in the preparation of SBA-15 (Santa Barbara Amoprhous-15)- catalyst.

Potassium oxalate monohydrate may be used in the synthesis of bis(2,2"-bipyridine) (oxalato-O,O′)nickel(ii) tetrahydrate, a mononuclear mixed-ligand complex.
