And the article contained the following:

Abstract: The efficient SBA-15 supported silver catalysts(Ag/SBA-15) were prepared and characterized by ICP-OES, XRD, TEM, SEM, XPS and N2 adsorption-desorption techniques. The catalysts exhibited an excellent catalytic activity for the aerobic oxidation of toluene to benzaldehyde under solvent-free conditions. Conversion of toluene and selectivity of benzaldehyde were 50% and 89% resp. over catalyst with 9.1 wt% Ag loading (10Ag/SBA-15). A wide range of substrates were tolerated under the selected reaction conditions. The kinetic study shows that the oxidation of toluene over 10Ag/SBA-15 is pseudo-first-order reaction and the activation energy Ea is 45.1 kJ/mol. A plausible mechanism involving oxygen free radicals was proposed for the aerobic oxidation reaction. Compared with the traditional method, the newly designed heterogeneous catalytic system shows better economic applicability, environmental friendliness and broader application prospects. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).SDS of cas: 578-58-5

This manuscript describes the development of a remarkably general palladium-catalyzed monoacylation of carbazoles using toluene derivatives playing the dual role of acyl source and organic solvent. The method uses NHPI as the cocatalyst and oxygen as the sole oxidant. Interestingly, the acylation of monosubstituted N-pyridylcarbazoles takes place regioselectively at the C-8 position. The scope of the method is explored using aldehyde as the acyl source. This highly site-selective acylation proceeds through a radical process. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Safety of 2-Methylanisole

Wang, Shuyuan; Xu, Dan; Chen, Yunlei; Zhou, Song; Zhu, Di; Wen, Xiaodong; Yang, Yong; Li, Yongwang published an article in 2020, the title of the article was Hydrodeoxygenation of anisole to benzene over an Fe2P catalyst by a direct deoxygenation pathway.Recommanded Product: 2-Methylanisole And the article contains the following content:

Developing economically viable and highly selective hydrodeoxygenation (HDO) catalysts for the C-O bond cleavage of lignin-derived aryl ethers is very important, but still challenging. Herein, a novel monometallic Fe2P catalyst was synthesized by a two-stage phosphorization method under mild conditions, which showed a high arene (benzene) selectivity of 96.7% among C6+ products with a turnover frequency of 8.2 x 10-3 mol molCO-1 s-1 in the HDO of anisole at 200掳C and ambient hydrogen pressure. Characterization results revealed that the crystal structure of the Fe2P catalyst was stable and no phosphorus loss occurred in the reduction and reaction process. The kinetic results indicated that the coverage of anisole was higher than that of H2 on the Fe2P catalyst. The anisole temperature-programmed surface reaction (anisole-TPSR) and d. functional theory (DFT) calculation results identified that the anisole HDO reaction mechanism is the direct cleavage of the Caryl-O bond of anisole to form C6H5* and CH3O* without forming the C6H5-OH-CH3 intermediate. These findings may contribute toward understanding the iron-based phosphide and guiding the catalyst design for the HDO of aryl ethers and related reactions. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Recommanded Product: 2-Methylanisole

On April 5, 2022, Shu, Junzheng; Wang, Zeyu; Zhang, Zhifang; Ding, Yichun; Zhang, Qinlong; Gao, Wenwen; Liu, Guilin; Yang, Yonglin published an article.Recommanded Product: 578-58-5 The title of the article was High-Performance Na-CH3ONa/�Al2O3 Catalysts for High-Efficiency Conversion of Phenols to Ethers. And the article contained the following:

An efficient alk. catalyst with porous structure (Na-CH3ONa/�Al2O3) was prepared by the melting method. The wastewater from the semicoke plant (WWSCP) was extracted multiple times with an isometric of di-Me carbonate (DMC)-cyclohexane mixed solvent at room temperature to obtain an organic phase (OP) with a high concentration of phenols. Ether (OPCP) was obtained by catalytic conversion of OP over catalyst Na-CH3ONa/�Al2O3 at 210掳C and reaction time of 2.5 h. Both OP and OPCP were analyzed with a gas chromatograph/mass spectrometer (GC/MS) and quadrupole exactive orbitrap mass spec trometer (QPEOTMS). The results showed that only DMC, phenol, o-Cresol and other monohydric phenols were detected in OP, and only other saturated ethers such as anisole and O-methylanisole were detected in OPCP. Through the study of the catalytic conversion of WWSCP-related model compound, it was found that Na-CH3ONa/�Al2O3 could effectively activate (deprotonate) phenol into phenate, and the strong nucleophilic oxyanion of phenate would attack the Me carbon and carbonyl carbon on DMC to obtain Me and methoxy groups. Thereby, phenate can be combined with Me and methoxy groups to acquire the product anisole. In addition, the catalyst Na-CH3ONa/�Al2O3 was found to still have high catalytic activity after 10 repeated cycles. It was speculated that this was related to the abundant microporous and mesoporous structure of the catalyst Na-CH3ONa/�Al2O3.

And the article contained the following:

The hydrodeoxygenation (HDO) activity of anisole has been investigated over Ni catalysts on mixed metal oxide supports containing Nb-Zr and Ti-Zr in 1:1 and 1:4 ratios. XRD patterns indicate the incorporation of Ti (or Nb) into the ZrO2 framework. XPS and oxygen pulse chemisorption analyses reveal that Ni/Ti1Zr4 and Ni/Nb1Zr4 possessed more oxygen vacancy sites than Ni/Ti1Zr1 and Ni/Nb1Zr1, resp. Correspondingly, the HDO activity of Ni/Ti1Zr4 and Ni/Nb1Zr4 was higher with an anisole conversion up to 30.7 and 34.4%, with high selectivity towards benzene (up to 64.7 and 63.3%), compared to corresponding Ni/Ti1Zr1 and Ni/Nb1Zr1 catalysts.

On July 31, 2021, Wong, Warren H. L.; Gries, Regine M.; Abram, Paul K.; Alamsetti, Santosh K.; Gries, Gerhard published an article.Electric Literature of 578-58-5 The title of the article was Attraction of Brown Marmorated Stink Bugs, Halyomorpha halys, to Blooming Sunflower Semiochemicals. And the article contained the following:

The polyphagous invasive brown marmorated stink bug, Halyomorpha halys, reportedly discriminates among phenol. stages of host plants. To determine whether olfaction is involved in host plant stage discrimination, we selected (dwarf) sunflower, Helianthus annuus, as a model host plant species. When adult females of a still-air laboratory experiment were offered a choice of four potted sunflowers at distinct phenol. stages (vegetative, pre-bloom, bloom, seeding), most females settled onto blooming plants but oviposited evenly on plants of all four stages. In moving-air two-choice olfactometer experiments, we then tested each plant stage vs. filtered air and vs. one another, for attraction of H. halys females. Blooming sunflowers performed best overall, but no one plant stage was most attractive in all experiments Capturing and analyzing (by GC-MS) the headspace odorants of each plant stage revealed a marked increase of odorant abundance (e.g., monoterpenes) as plants transitioned from pre-bloom to bloom. Analyzing the headspace odorant blend of blooming sunflower by gas chromatog.-electroantennog. detection (GC-EAD) revealed 13 odorants that consistently elicited responses from female H. halys antennae. An 11-component synthetic blend of these odorants attracted H. halys females in laboratory olfactometer experiments Furthermore, in field settings, the synthetic blend enhanced the attractiveness of synthetic H. halys pheromone as a trap lure, particularly in spring (Apr. to mid-June). A simpler yet fully effective sunflower semiochem. blend could be developed and coupled with synthetic H. halys aggregation pheromones to improve monitoring efforts or could improve the efficacy of modified attract-and-kill control tactics for H. halys.

Verevkin, Sergey P.; Turovtsev, Vladimir V.; Andreeva, Irina V.; Orlov, Yurij D.; Pimerzin, Aleksey A. published an article in 2021, the title of the article was Webbing a network of reliable thermochemistry around lignin building blocks: tri-methoxy-benzenes.Formula: C8H10O And the article contains the following content:

Methoxy-substituted benzenes are the simplest fragments from the lignin separation feedstock. Extensive exptl. thermochem. studies of these compounds were carried out, including vapor pressure measurements, combustion and differential scanning calorimetry. These data were evaluated using empirical, semi-empirical and quantum chem. methods. The consistent sets of evaluated thermodn. data were used to design the method for predicting enthalpies of vaporization and enthalpies of formation of di- and tri-substituted benzenes. It has been found that the agglomeration of substituents on the benzene ring has dramatic consequences for the energetics of the mol. (in terms of the enthalpy of formation), as well as for the energetics of intermol. interactions (in terms of the enthalpy of vaporization). These observations are essential to reliably assess the energetics of the mols. that appear in reaction products of lignin transformations in value-adding chems. and materials.

On January 5, 2020, Blanco, Elodie; Rosenkranz, Andreas; Espinoza-Gonzalez, Rodrigo; Fuenzalida, Victor M.; Zhang, Zhenyu; Suarez, Sebastian; Escalona, Nestor published an article.Quality Control of 2-Methylanisole The title of the article was Catalytic performance of 2D-Mxene nano-sheets for the hydrodeoxygenation (HDO) of lignin-derived model compounds.

2D Mxene nanosheets (Ti3C2Tx) were investigated for the hydrodeoxygenation of guaiacol as a lignin-derived model compound The catalyst was characterized by TEM, XPS, Raman spectroscopy and TPR. The acid-base properties were measured by TPD-NH3 and TPRe-MeOH. Phenol was the main product obtained, and methylanisole was observed as the second main product. The study of Anisole conversion shows that methylanisole was likely obtained by a bimol. transalkylation. Such formation, which has only been reported over acid catalysts, was associated to the combined action of acid-base pairs identified.

On May 15, 2021, Li, Mingxue; Mei, Qiong; Wei, Bo; An, Zexiu; Sun, Jianfei; Xie, Ju; He, Maoxia published an article.Formula: C8H10O The title of the article was Mechanism and kinetics of ClO·-mediated degradation of aromatic compounds in aqueous solution: DFT and QSAR studies. And the article contained the following:

The action of ClO· is more prominent than HO· and Cl· in the advanced oxidation degradation of some pollutants. However, studies on the pollutant degradation mechanism and kinetics by ClO· are limited. In this study, 43 different kind of aromatic compounds which are important anthropogenic and natural water pollutants were selected as models to investigate their ClO· oxidation mechanism and kinetics computationally. The results showed that radical adduct formation (RAF) rather than single electron transfer (SET) reaction was prominent in ClO·-initiated reactions of aromatic compounds In subsequent reactions of the ClO-adduct, the Cl end of the -OCl moiety shifted to the benzene ring, which was the key to hydroxylation and chlorination of aromatic compounds by ClO·. The calculated ClO· initiated reaction rate constants (k·ClO) of aromatic compounds were 102-1010 M-1 s-1. ClO· was highly reactive to phenolates, anilines and alkoxy/hydroxyl aromatic compounds Upon the deprotonation of phenol to phenolate, the k·ClO value increased by 4 orders of magnitude. The k·ClO values of alkoxybenzenes were higher for compounds with shorter alkyl side chains and more alkoxy substituents. The k·ClO increased for anilines with longer alkyl side chains. The k·ClO quant. structure-activity relationships (QSARs) models were developed to predict the reactivity of ClO· to complex aromatic compounds in aquatic systems. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Formula: C8H10O
