Aluminium triacetate is a chemical compound that is prepared by heating aluminium chloride (AlCl 3) or Al powder with a mixture of acetic acid (CH 3 COOH) and acetic anhydride (C 4 H 6 O 3). [5] It is referred as the normal salt and is only made in the absence of water at a relatively high temperature like 180 °C. [1]
The formula Al(CH 3 CO 2) 3 indicates the presence of aluminium centres in the +3 oxidation state and acetate groups in a ratio of 1:3. Images used to represent this substance, such as those shown at left, represent two highly oversimplified approximations of the solid-state structure: the first is as a purely ionic salt with a single aluminium(III) cation (Al 3+) surrounded by and associated ...

Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.
Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...
An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula C 2 H 3 O − 2.
Aluminium monoacetate, also known as dibasic aluminium acetate, and formally named dihydroxy aluminium acetate, is a salt of aluminium with acetic acid. It has the formula Al(OH) 2 (CH 3 COO), with aluminium in an oxidation state of +3, and appears under standard conditions as a white solid powder.
The enzyme acetylacetone dioxygenase cleaves a central carbon-carbon bond of acetylacetone, producing acetate and 2-oxopropanal. The enzyme is iron(II)-dependent, but it has been proven to bind to zinc as well. Acetylacetone degradation has been characterized in the bacterium Acinetobacter johnsonii.
