A New Method for Synthesis of Manganese(III) Acetate Dihydrate

Abstract

A new method is reported for the synthesis of manganese(III) acetate dihydrate from manganese(II) acetate tetrahydrate, lead(IV) oxide and acetic acid as solvent. Melting point, mixed melting point with manganese(III) acetate dihydrate obtained by the well–known Christiensen method, elemental analyses, and potentiometric titration with a standard hydroquinone solution in acetic acid showed that the compound obtained by the new method was very pure (99.6%). In addition a solution of the compound in acetic acid was used to titrate potentiometrically some hydrazine derivatives and excellent results were obtained.
