Lutetium(III) acetate is the acetate salt of lutetium with the chemical formula of Lu(CH3COO)3.
Preparation
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 acidJanina Wysocka-Lisek. Study of topochemical preparation of rare earth acetates. Biuletyn Lubelskiego Towarzystwa Naukowego, Matematyka-Fizyka-Chemia, 1981. 23 (2): 145-149. or 50% acetic acid solution.
Properties
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.
Lutetium(III) acetate reacts with ammonium fluoride to produce lutetium fluoride:
Lu(CH3COO)3 + 3 NH4F → LuF3 + 3 CH3COONH4
The F− formed by the hydrolysis of fluoroborates (such as [BMIM]BF4)Note: The original text is "BMIM = 1-butyl-2-methylimidazolium", which is supposed to be 1-butyl-3-methylimidazolium can also precipitate with Lu3+.
Reaction with phosphoric acid to produce lutetium phosphate:
Lu(CH3COO)3 + H3PO4 → LuPO4 + 3 CH3COOH
