Ácidos Benzóicos

4-Formylbenzoic acid is an organic compound with the molecular formula CH2=C(O)CH=CHCO2H. It is a white solid that is soluble in water and has a strong, unpleasant odor. 4-Formylbenzoic acid has been shown to have affinity for binding to odorous molecules such as sulfur compounds, amines, and mercaptans. The binding of these molecules to the 4-formylbenzoic acid leads to a decrease in their odor concentration. This process can be done using electrochemical impedance spectroscopy or optical sensors. The oxidation of 4-formylbenzoic acid by trifluoroacetic acid produces 2-formylphenol and formaldehyde, which are themselves volatile compounds with an unpleasant odor. These reactions may be used as wastewater treatment methods. Langmuir adsorption isotherm may be used as an analytical method for measuring the concentration of 4-formylbenzoic acid

Ethyl 4-nitrobenzoate is a compound that is used to synthesize other drugs, such as erythromycin. It is also an intermediate in the synthesis of some pesticides and dyes. The second-order rate constant for the reaction of ethyl 4-nitrobenzoate with phosphotungstic acid has been measured at 0.058/min at 25°C. This reaction is catalyzed by recombinant cytochrome P450 (P450) enzymes from human liver preparations and cationic surfactants such as nitrobenzene or sodium carbonate, which are known to form hydrogen bonds with the protonated nitrogen atom on the aromatic ring of ethyl 4-nitrobenzoate. Ethyl 4-nitrobenzoate is also used clinically to treat gastric ulcers, although it can be toxic if taken in large doses or over a long period of time.

4-Vinylbenzoic acid is a water-insoluble polymer that has been shown to have bacteriostatic and fungistatic properties. 4-Vinylbenzoic acid inhibits bacterial growth by binding to the enzyme diphenolase, which is involved in the synthesis of cell wall precursors. This polymer also binds to cationic surfactants and is soluble in organic solvents such as ethanol and acetone. The mechanism of inhibition of fungal growth is not known, but it may be due to hydrogen bonding interactions with the cell membrane.
4-Vinylbenzoic acid has been shown to be effective against human serum, although it does not inhibit bacterial growth in this medium.
