Aluminium acetate
Encyclopedia
Aluminium acetates are the aluminium
salt
s of acetic acid
. Three such salts exist:
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 sodium aluminate
(NaAlO2) with acetic acid.
Aluminium
Aluminium or aluminum is a silvery white member of the boron group of chemical elements. It has the symbol Al, and its atomic number is 13. It is not soluble in water under normal circumstances....

Salt
In chemistry, salts are ionic compounds that result from the neutralization reaction of an acid and a base. They are composed of cations and anions so that the product is electrically neutral...

Acetic acid
Acetic acid is an organic compound with the chemical formula CH3CO2H . It is a colourless liquid that when undiluted is also called glacial acetic acid. Acetic acid is the main component of vinegar , and has a distinctive sour taste and pungent smell...

Barium acetate
Barium acetate is the salt of barium and acetic acid.-Preparation:Barium acetate is generally produced by the reaction of acetic acid with barium carbonate:The reaction is performed in solution and the barium acetate crystallizes out...

Aluminium hydroxide
Aluminium hydroxide, Al3, ATH, sometimes erroneously called Hydrate of alumina, is found in nature as the mineral gibbsite and its three, much more rare forms, polymorphs: bayerite, doyleite and nordstrandite. Closely related are aluminium oxide hydroxide, AlO, and aluminium oxide, Al2O3,...

Acetic anhydride
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula 2O. Commonly abbreviated Ac2O, it is the simplest isolatable acid anhydride and is a widely used reagent in organic synthesis...

The diacetate is prepared in a reaction of sodium aluminate
Sodium aluminate
Sodium aluminate is an important commercial inorganic chemical. It works as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate is a white crystalline solid having a formula variously given as NaAlO2, NaAl4 , Na2O·Al2O3, or Na2Al2O4...
