In the solid state, three salts exist under this name:

  1. Neutral aluminium triacetate, Al(CH3CO2)3, which is formally called aluminium acetate under IUPAC rules, with CAS RN 139-12-8[3]
  2. Basic aluminium diacetate, HOAl(CH3CO2)2, also known as basic aluminium acetate, and formally named hydroxyaluminium diacetate, with CAS RN 142-03-0[3]
  3. Basic aluminium monoacetate, (HO)2AlCH3CO2, also known as dibasic aluminium acetate, and formally named dihydroxyaluminium acetate, with CAS RN 7360-44-3

In aqueous solution, aluminium triacetate hydrolyses to form a mixture of the other two,[1] and all solutions of all three can be referred to as "aluminium acetate" as the species formed co-exist and inter-convert in chemical equilibrium.

Aluminium triacetate
Main article: Aluminium triacetate

Aluminium triacetate is a chemical compound that is a salt that is formally named by IUPAC nomenclature as aluminium acetate. It has a chemical formula of Al(C2H3O2)3 . It has a molecular mass of 204.11 g/mol and a density of 1.002 g/cm3. At standard state, aluminium triacetate looks like white solid crystals.

Aluminium diacetate
Main article: Aluminium diacetate

Aluminium diacetate is a chemical compound that is a salt that is formally named by IUPAC nomenclature as hydroxyaluminium diacetate and commonly known as basic aluminium acetate. It has a chemical formula of HOAl(CH3CO2)2. It has a molecular mass of 162.077 g/mol and it looks like white, opaque crystals at standard state.

Aluminium monoacetate

Aluminium monoacetate is a chemical compound that is a salt that is formally named by IUPAC nomenclature as dihydroxyaluminium acetate and commonly known as dibasic aluminium acetate. It has a chemical formula of (HO)2AlCH3CO2. It has a molecular mass of 120.04 g/mol and it looks like white powder at standard state.[4]
