Lutetium(III) acetate is the acetate saltoflutetium with the chemical formula of Lu(CH₃COO)₃.

Preparation[edit]

Lutetium(III) acetate can be prepared through neutralisation, where a lutetium salt reacts with acetic acid to produce lutetium acetate and water:

Lu₂O₃ + 6 CH₃COOH → 2 Lu(CH₃COO)₃ + 3 H₂O

Lu(OH)₃ + 3 CH₃COOH → Lu(CH₃COO)₃ + 3 H₂O

Lutetium(III) acetate also can be obtained by reacting lutetium oxide with gaseous acetic acid^[1] or 50% acetic acid solution.^[2]

Properties[edit]

Lutetium(III) acetate is a water-soluble salt that forms colorless crystals. It forms crystalline hydrates in the form of Lu(CH₃COO)₃•nH₂O, where n = 1 or 4.^{[citation needed]}

Lutetium(III) acetate reacts with ammonium fluoride to produce lutetium fluoride:

Lu(CH₃COO)₃ + 3 NH₄F → LuF₃ + 3 CH₃COONH₄

The F⁻ formed by the hydrolysisoffluoroborates (such as [BMIM]BF₄)^[3] can also precipitate with Lu³⁺.^[4]

Reaction with phosphoric acid to produce lutetium phosphate:^[5]

Lu(CH₃COO)₃ + H₃PO₄ → LuPO₄ + 3 CH₃COOH
