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
[edit] 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.
- The molar mass is 204 g/mol*
[edit] Applications
The diacetate is used as an antiseptic.
