acetyl chloride SOCl 2 acetic acid (i) Li[AlH 4], ether (ii) H 3 O + ethanol Two typical organic reactions of acetic acid Acetic acid undergoes the typical chemical reactions of a carboxylic acid. Upon treatment with a standard base, it converts to metal acetate and water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH 2 COOLi. Reduction of acetic ...
The acid-growth hypothesis is a theory that explains the expansion dynamics of cells and organs in plants. It was originally proposed by Achim Hager and Robert Cleland in 1971. [1] [2] They hypothesized that the naturally occurring plant hormone, auxin (indole-3-acetic acid, IAA), induces H + proton extrusion into the apoplast.
Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [1] IAA is a derivative of indole, containing a carboxymethyl substituent. It is a colorless solid that is soluble in polar organic ...
Cellulose is a carbohydrate, specifically a polysaccharide, which can be found in the cell walls of plants, algae, fungi, and some bacteria. Through its production of acetic acid and oxidation of ethanol, A. aceti plays a crucial role in synthesis of bacterial cellulose. Bacterial cellulose is unique from plant cellulose due to its highly pure ...
Juglone is an example of such a molecule inhibiting the growth of other plant species around walnut trees. [citation needed] The aquatic vascular plant Myriophyllum spicatum produces ellagic, gallic and pyrogallic acids and (+)-catechin, allelopathic phenolic compounds inhibiting the growth of blue-green alga Microcystis aeruginosa.

Vinegar typically contains from 5% to 18% acetic acid by volume. [1] Usually, the acetic acid is produced by a double fermentation, converting simple sugars to ethanol using yeast and ethanol to acetic acid using acetic acid bacteria. [2] Many types of vinegar are made, depending on source materials.
Ethanol fermentation is not 100% selective with side products such as acetic acid and glycols. They are mostly removed during ethanol purification. Fermentation takes place in an aqueous solution. The resulting solution has an ethanol content of around 15%. Ethanol is subsequently isolated and purified by a combination of adsorption and ...
The best known phenoxy herbicides are (4-chloro-2-methylphenoxy)acetic acid , 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T). [2] Analogues of each of these three compounds, with an extra methyl group attached next to the carboxylic acid , were subsequently commercialised as mecoprop , dichlorprop and ...
