'''Lanthanum acetate''' is an [[Chemistry:Inorganic compound|inorganic compound]], a salt of [[Chemistry:Lanthanum|lanthanum]] with [[Chemistry:Acetic acid|acetic acid]] with the chemical formula {{chem2|La(CH3COO)3}}.<ref>{{cite book |title=User guide and indices to the initital inventory, substance name index |date=1979 |publisher=U.S. Government Printing Office |page=856 |url=https://books.google.com/books?id=PCwBQIhLMrsC&dq=lanthanum(III)+acetate&pg=PA856 |access-date=20 March 2023 |language=en}}</ref>

==Synthesis==
Lanthanum acetate can be formed by the reaction of lanthanum(III) oxide and [[Chemistry:Acetic anhydride|acetic anhydride]]:

::{{chem2|La2O3 + 3(CH3CO)2O -> 2La(CH3COO)3}}

It is also made in a reaction of lanthanum oxide with 50% [[Chemistry:Acetic acid|acetic acid]]:

::{{chem2|La2O3 + 6CH3COOH -> 2La(CH3COO)3 + 3H2O}}

==Physical properties==
Lanthanum(III) acetate forms colorless crystals.

Lanthanum acetate dissolves in water.

Lanthanum acetate forms hydrates of the composition {{chem2|La(CH3COO)3•''n''H2O}}, where ''n'' = 1 and 1.5.<ref>{{cite web |title=Lanthanum(III) acetate hydrate {{!}} Lanthanum Triacetate Hydrate {{!}} C6H11LaO7 |url=https://ereztech.com/product/lanthanumiii-acetate-hydrate-100587-90-4/ |publisher=Ereztech |access-date=20 March 2023}}</ref><ref>{{cite web |title=15299 Lanthanum(III) acetate sesquihydrate, 99.9% (REO) |url=https://www.alfa.com/en/catalog/015299/ |publisher=[[Company:Alfa Aesar|Alfa Aesar]] |access-date=20 March 2023}}</ref>

Lanthanum acetate and its hydrates decompose when heated.

==Uses==
Lanthanum acetate is used in specialty glass manufacturing and in [[Earth:Water treatment|water treatment]].

Also, it is used to produce porous [[Chemistry:Lanthanum oxyfluoride|lanthanum oxyfluoride]] (LaOF) films.<ref>{{cite book |last1=Shimoda |first1=Tatsuya |title=Nanoliquid Processes for Electronic Devices: Developments of Inorganic Functional Liquid Materials and Their Processing |date=5 February 2019 |publisher=Springer |isbn=978-981-13-2953-1 |page=498 |url=https://books.google.com/books?id=LciGDwAAQBAJ&dq=lanthanum(III)+acetate&pg=PA498 |access-date=20 March 2023 |language=en}}</ref>

It is also used as a component in the production of ceramic products and as a catalyst in the pharmaceutical industry.
