Degradation of 2,4-dihydroxibenzoic acid by vacuum UV process in aqueous solution: Kinetic, identification of intermediates and reaction pathway

Reaction pathway of the degradation of the p-hydroxybenzoic acid by sulfate radical generated by ionizing radiations

“…ortho and para position of the OH group). This result is in accordance with the results of Azrague et al (2012) which detected these two compounds as by-products of 2,4-dihydroxybenzoic acid degradation by hydroxyl radical. They also found that the formation of 2,4,6-trihydroxybenzoic acid is not likely to occur.…”

Iron cycling during the autocatalytic decomposition of benzoic acid derivatives by Fenton-like and photo-Fenton techniques

“…e Trace amounts of the corresponding m/z were observed by HPLC-MS. f No significant peaks were observed for the corresponding m/z by HPLC-MS in Fenton systems. However, this compound has been detected during the treatment of 2,4dHBA by VUV photolysis [55]. g Note that the HQ-like structures are also CAT-like, but only one of the three structures is purely CAT-like and the effect of HQ-like structures prevails.…”

A combined experimental and theoretical analysis on molecular structure and vibrational spectra of 2,4-dihydroxybenzoic acid

“…In addition, it is very efficient to reduce oxidative damage [7] associated with various diseases such as cancer, cataracts, arthritis, and diabetes. Meanwhile, as a precursor to the quinones which has an deleterious effect on environment, it can often cause water pollution [8].…”
