Lanthanum acetate is an inorganic compound, a salt of lanthanum with acetic acid with the chemical formula La(CH3COO)3.[1]
Synthesis[edit]
Lanthanum acetate can be formed by the reaction of lanthanum(III) oxide and acetic anhydride:
- La2O3 + 3(CH3CO)2O → 2La(CH3COO)3
It is also made in a reaction of lanthanum oxide with 50% acetic acid:
- La2O3 + 6CH3COOH → 2La(CH3COO)3 + 3H2O
Physical properties[edit]
Lanthanum(III) acetate forms colorless crystals.
Lanthanum acetate dissolves in water.
Lanthanum acetate forms hydrates of the composition La(CH3COO)3•nH2O, where n = 1 and 1.5.[2][3]
Lanthanum acetate and its hydrates decompose when heated.
Uses[edit]
Lanthanum acetate is used in specialty glass manufacturing and in water treatment.
Also, it is used to produce porous lanthanum oxyfluoride (LaOF) films.[4]
It is also used as a component in the production of ceramic products and as a catalyst in the pharmaceutical industry.
