When treating phenol/substituted phenol-containing wastewater, an intermediate chem. step of partial oxidation is often used to facilitate the downstream biodegradation process. Ozonation is a candidate method for partial oxidation of phenolic compounds This work assessed the kinetics of ozonation reactions of 20 substituted phenols using the renowned theory of mass transfer with chem. reaction. A stirred (Lewis) cell with flat interface was used as a model contactor. Second-order rate constants for reactions with the selected phenolic compounds were in the 104-107/M-s range. The rate constant for phenol ozonation was 5.06 × 106/M-s. The liquid-side mass transfer coefficient, estimated using the chem. method, was (kL = 0.052 cm/s) in line with those typical of stirred-cell reactors. This work is useful to design, operate, and scale-up ozonation wastewater treatment reactors. In addition to this study using m-Methoxyphenol, there are many other studies that have used m-Methoxyphenol(cas: 150-19-6COA of Formula: C7H8O2) was used in this study.

Cao, Haijie; Wang, Kuikui; Yang, Zhengqiang; Wu, Shijie; Han, Dandan published an article in 2021. The article was titled 《Quantum chemical study on the ozonolysis mechanism of guaiacol and the structure-reactivity relationship of phenols with hydroxyl, methoxy, and methyl substituents》, and you may find the article in Chemical Engineering Journal (Amsterdam, Netherlands).Related Products of 150-19-6 The information in the text is summarized as follows:

Quantum chem. calculations with the M06-2X method were performed to uncover the ozonolysis mechanism of guaiacol and several hydroxylated, methoxylated, and methylated phenols to improve the understanding of the ozone-induced attenuation of phenolic compounds The detailed kinetic properties were obtained by the transition state theory (TST) and the Rice – Ramsperger – Kassel – Marcus (RRKM) theory. Results confirm that the primary ozonides originated from guaiacol occupy considerably long retention time than the short-lived primary ozonides formed from vinyl-type compounds in the air. The TST rate constant of guaiacol ozonolysis is calculated with a value of 8.81 x 10-20 cm3 mol.-1 s-1 at room temperature The RRKM results prove that the rate constant is pos. dependent on temperature but shows no relation with pressure. The reactivity of substituted phenols exhibits a strong correlation with the ozone affinity of carbon atoms and the orbital energy difference (ELo-Hac) between the LUMO of O3 and the HOMO of phenols. The substituents can reduce the value of ELo-Hac and improve the phenols’ reactivity, especially when they locate at the ortho- and para-position. The substituents also improve the ozone affinity of carbon atoms due to the electron-withdrawing effect. The Me group delivers a moderate impact on the reactivity compared to hydroxyl and methoxy groups. The results came from multiple reactions, including the reaction of m-Methoxyphenol(cas: 150-19-6Related Products of 150-19-6)

The title of the article was 《Curtius rearrangement reactions using 7-methoxybenzofuran-2-carbonylazide》.Related Products of 150-19-6 The author mentioned the following in the article:

The synthetic investigation of 7-methoxybenzofuranyl-carbamates (7-Methoxy-benzofuran-2-yl)-carbamic acid Et ester and I (R1 = C6H5, 4-ClC6H4, 2-ClC6H4, etc.) and carbamides II (R2 = C6H5, 4-ClC6H4, cyclohexyl, etc.) via the Curtius rearrangement of 7-methoxybenzofuran-2-carbonylazide has been reported. The required intermediate carbonyl azide was synthesized from ethyl-7-methoxybenzofuran-2-carboxylate by two established synthetic routes: (1) 7-methoxy-benzofuran-2-carboxylic acid and 7-methoxy-benzofuran-2-carbonyl chloride and (2) 7-methoxy-benzofuran-2-carboxylic acid hydrazide. The carbonyl azide was subjected to Curtius rearrangement in anhydrous medium with ethanol and various aromatic phenols to obtain carbamates (7-methoxy-benzofuran-2-yl)-carbamic acid Et ester and I while with primary amines and cyclohexylamine to obtain carbamides II. The structures of all the synthesized compounds I and II were confirmed by their IR, 1HNMR and mass spectral data. All the newly synthesized compounds I and II were screened for anti bacterial activity and antifungal activity. Few selected compounds were screened for their anti oxidant properties and DNA cleavage studies. Few compounds exhibited appreciable activity.

《Development of a method to measure laccase activity on methoxyphenolic food ingredients and isomers》 was written by Manzano-Nicolas, Jesus; Marin-Iniesta, Fulgencio; Taboada-Rodriguez, Amaury; Garcia-Canovas, Francisco; Tudela-Serrano, Jose; Munoz-Munoz, Jose Luis. Product Details of 150-19-6 And the article was included in International Journal of Biological Macromolecules in 2020. The article conveys some information:

We studied the laccase-catalyzed oxygenation of methoxyphenolic food ingredients, such as 2-methoxyphenol (guaiacol) and 2,6-dimethoxyphenol (syringol), isomers such as 3- and 4-methoxyphenol, and 2,3-, 3,4- and 3,5-dimethoxyphenol. These methoxyphenolic substrates generate unstable free radicals, which leads to the erroneous determination of steady state rates. The addition of small quantities of ascorbic acid as coupling reagent generates a lag period because it reduces free radicals to methoxyphenols. Measurement of the length of the lag period provides the reliable determination of true steady state rates. We describe the application of this chronometric method to the kinetic characterization of the oxidation of the above methoxyphenolic substrates by Trametes versicolor laccase. The experimental part of the paper was very detailed, including the reaction process of m-Methoxyphenol(cas: 150-19-6Product Details of 150-19-6)

《Synthesis of coumarin derivatives in a microfluidic flow system employing the Pechmann condensation: A case study》 was written by Liu, Ling-Kang; Deng, Jhao-Hong; Guo, Yang-Ming. COA of Formula: C7H8O2 And the article was included in Journal of the Chinese Chemical Society (Weinheim, Germany) in 2020. The article conveys some information:

For the synthesis of coumarin derivatives using the Pechmann condensation scheme, an acidic ionic liquid catalyst, abbreviated as [EBsImH][HSO4], was prepared from the ring opening of 1,4-butanesultone by 1-ethylimidazole, followed by the addition of 1 equivalent H2SO4(c). The [EBsImH][HSO4]-catalyzed Pechmann condensation reactions proceeded smoothly in a batch setup, with recyclable [EBsImH][HSO4] showing great catalytic activity. The acidic ionic liquid catalyst [EBsImH][HSO4] was recovered from EtOAc/H2O extraction of the product mixture, where the H2O layer was worked up and dried for reuse in consecutive runs of the Pechmann condensation reactions, maintaining >85% conversion for four times. The catalytic reactions were also carried out in a microfluidic flow setup. The flow parameters, the reactant molar amounts, and the addnl. H2SO4 as a modifying acid catalyst were optimized in the current case study. A min. conversion rate of 2.8 g/h of coumarin derivatives was demonstrated. The results came from multiple reactions, including the reaction of m-Methoxyphenol(cas: 150-19-6COA of Formula: C7H8O2)
