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.
