Aluminium acetates are the aluminium salts of acetic acid. Three such salts exist:
- neutral aluminium triacetate, Al(C2H3O2)3
- basic Aluminium diacetate, HOAl(C2H3O2)2
- basic Aluminium monoacetate, (HO)2AlC2H3O2
Synthesis
The triacetate forms when aluminium sulfate is mixed with barium acetate. Another synthetic method is by bringing together aluminium hydroxide, acetic anhydride and glacial acetic acid in water, forming the basic aluminium monoacetate
The diacetate is prepared in a reaction of NaAlO2 with acetic acid.
Applications
The diacetate is used as an antiseptic.
