On February 8, 2022, Zhang, Jinhong; Sekyere, Daniel T.; Niwamanya, Noah; Huang, Yansheng; Barigye, Andrew; Tian, Yuanyu published an article.COA of Formula: C8H10O2 The title of the article was Study on the Staged and Direct Fast Pyrolysis Behavior of Waste Pine Sawdust Using High Heating Rate TG-FTIR and Py-GC/MS. And the article contained the following:

To understand the fast pyrolysis kinetics and product evolution of waste pine sawdust, high heating rate thermogravimetry-Fourier transform IR (TG-FTIR) was used to obtain the kinetic parameters and the chem. groups formed during the pyrolysis process, while pyrolysis-gas chromatog./mass spectrometry (Py-GC/MS) was used to investigate the detailed compositions of products under the staged (seven stages from 300 to 600°C) and direct fast pyrolysis process. Spectral bands were identified for acids, alcs., aldehydes, aromatics, esters, ethers, hydrocarbons, ketones, phenols, and sugars. Research found that the apparent activation energy for fast pyrolysis is much higher than that of slow pyrolysis. The evolution of CO2 is the major deoxygenation route. Cracking mainly occurred at the 450°C stage with phenols, ketones, aldehydes, and sugars as the main products. The product distributions for different stages are significantly different; the selectivity of aldehydes decreased, while phenols showed an upward trend with an increase in pyrolysis temperature Ketones and sugars reached their peak values at 450°C. The changes in the mol. composition of each stage helped to understand the pyrolysis process. Compared with the staged pyrolysis, the direct pyrolysis process had higher selectivity of acids, aldehydes, esters, and sugars and lower selectivity of phenols, ketones, and alcs. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).COA of Formula: C8H10O2

On March 30, 2022, Wang, Chao; Li, Juan; Zhang, Ya; He, Zhongrong; Zhang, Yin; Zhang, Xingmin; Guo, Zhuoyue; Huang, Jianan; Liu, Zhonghua published an article.Quality Control of 1,2-Dimethoxybenzene The title of the article was Effects of electrostatic spray drying on sensory qualities, aroma profile and microstructural features of instant Pu-erh tea. And the article contained the following:

The sensory qualities, aroma profile, and microstructural features of instant Pu-erh teas (IPTs) produced by electrostatic spray drying (ESD) were evaluated by sensory and instrumental analyses and compared with those produced by other drying methods (freeze-drying [FD], vacuum drying [VD], and conventional spray drying [CSD]). The sensory qualities of ESDIPT were similar to those of FDIPT, and better than those of VDIPT and CSDIPT. Eighty-eight volatiles were detected in all IPTs, and 45 odor-active compounds were captured. Most of their OAVs were higher in ESDIPT than in VDIPT and CSDIPT but were lower than those in FDIPT. Dihydro-β-ionone had the highest OAV. Aroma recombination experiments were performed to verify the identification results. ESDIPT was present in the shape of microspheres with many regular concave surfaces, which was different from those treated by other drying methods. In terms of sensory quality and productivity, ESD would be a potential method for IPT production The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Quality Control of 1,2-Dimethoxybenzene

Adilina, Indri Badria; Widjaya, Robert Ronal; Hidayati, Luthfiana Nurul; Supriadi, Edi; Safaat, Muhammad; Oemry, Ferensa; Restiawaty, Elvi; Bindar, Yazid; Parker, Stewart F. published an article in 2021, the title of the article was Understanding the Surface Characteristics of Biochar and Its Catalytic Activity for the Hydrodeoxygenation of Guaiacol.Formula: C8H10O2 And the article contains the following content:

Biochar (BCR) was obtained from the pyrolysis of a palm-oil-empty fruit bunch at 773 K for 2 h and used as a catalyst for the hydrodeoxygenation (HDO) of guaiacol (GUA) as a bio-oil model compound Brunauer-Emmet-Teller surface area anal., NH3 and CO2-temperature-programmed desorption, scanning electron microscope-dispersive X-ray spectroscopy, CHN anal. and X-ray fluorescence spectroscopy suggested that macroporous and mesoporous structures were formed in BCR with a co-presence of hydrophilic and hydrophobic sites and acid-base behavior. A combination of IR, Raman and inelastic neutron scattering (INS) was carried out to achieve a complete vibrational assignment of BCR. The CH-OH ratio in BCR is ∼5, showing that the hydroxyl functional groups are a minority species. There was no evidence for any aromatic C-H stretch modes in the IR, but they are clearly seen in the INS and are the majority species, with a ratio of sp3-CH:sp2-CH of 1:1.3. The hydrogen bound to sp2-C is largely present as isolated C-H bonds, rather than adjacent C-H bonds. The Raman spectrum shows the characteristic G band (ideal graphitic lattice) and three D bands (disordered graphitic lattice, amorphous carbon, and defective graphitic lattice) of sp2 carbons. Adsorbed water in BCR is present as disordered layers on the surface rather than trapped in voids in the material and could be removed easily by drying prior to catalysis. Catalytic testing demonstrated that BCR was able to catalyze the HDO of GUA, yielding phenol and cresols as the major products. Phenol was produced both from the direct demethoxylation of GUA, as well as through the demethylation pathway via the formation of catechol as the intermediate followed by deoxygenation. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Formula: C8H10O2

And the article contained the following:

Herein, a mild metal-free and efficacious route for the synthesis of biol. important 3-aryl oxindole derivatives I [R = H, OH, 4-MeOC6H4, etc.; R1 = H, Me, Br, etc.; R2 = H, NO2, Cl; R3 = H, Me, Bn, Ts; Ar = 4-HOC6H4, 2,4,6-tri-MeOC6H2, 1H-indol-3-yl, etc.] was described. Using Lambert salt-initiated hydroarylation of isatin, a diverse array of monoarylated products, sym./unsym. double-arylated products and deoxygenated hydroarylated products could be synthesized from the single starting substrate in good to excellent yields. A preliminary mechanistic study revealed that the reaction proceeded via a monoarylated product followed by a nucleophilic attack by another electron-rich arene nucleophile under mild conditions. The potential of newly synthesized sym./unsym. 3,3-disubstituted oxindole, 3-substituted 3-hydroxy oxindoles, 3,3-di(indolyl)indolin-2-ones, and α-aryl oxindoles as valuable building blocks was further illustrated. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Formula: C8H10O2

Salamanca, Vanesa; Albeniz, Ana C. published an article in 2021, the title of the article was Faster palladium-catalyzed arylation of simple arenes in the presence of a methylketone: beneficial effect of an a priori interfering solvent in C-H activation.Electric Literature of 91-16-7 And the article contains the following content:

The arylation of arenes with no directing groups (non-chelate assisted) was carried out using the cooperating ligand [2,2′-bipyridin]-6(1H)-one (bipy-6-OH), the use of a moderately coordinating solvent allows a decrease of the amount of arene used. Moreover, for the least coordinating arenes, the co-solvent produced a significant accelerating effect by altering the concentration and relative stability of relevant metal species in the catalytic cycle as well as the catalyst resting state. t-Bu Me ketone (pinacolone) was one of the most effective co-solvents: Even if the ketone C-H bond cleaves easily, the final products were determined by the reductive elimination step (the product-forming step) so the target biaryl products were selectively observed The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Electric Literature of 91-16-7

A conjugated copper(II) catecholate based metal-organic framework (namely Cu-DBC) was prepared using a D2-sym. redox-active ligand in a copper bis(dihydroxy) coordination geometry. The π-d conjugated framework exhibits typical semiconducting behavior with a high elec. conductivity of ca. 1.0 S m-1 at room temperature Benefiting from the good elec. conductivity and the excellent redox reversibility of both ligand and copper centers, Cu-DBC electrode features superior capacitor performances with gravimetric capacitance up to 479 F g-1 at a discharge rate of 0.2 A g-1. Moreover, the sym. solid-state supercapacitor of Cu-DBC exhibits high areal (879 mF cm-2) and volumetric (22 F cm-3) capacitances, as well as good rate capability. These metrics are superior to most reported MOF-based supercapacitors, demonstrating promising applications in energy-storage devices.

Designing and constructing novel topol. all-solid-state polymer electrolyte (SPE) matrixes can improve the ionic conducting ability of the prepared SPEs compared with the linear ones. Here, we construct a novel topol. polymer electrolyte matrix using triphenylene as core and block poly(Me methacrylate)-poly(poly[ethylene glycol] Me ether methacrylate) as arm. Specifically, the arm is attached onto the core via sequential atom transfer radical polymerization The mol. weight of the polymers is well controlled via adjusting the inventory rating of monomers, the optimal SPE obtained via solution casting has an ambient temperature ionic conductivity of 3.69 × 10-5 S cm-1, which is higher than typical linear poly(ethylene oxide)-based SPE (usually 10-6-10-8 S cm-1). The electrochem. performance is further improved through adding given contents of graphene-oxide into the SPE. Thus, we believe, through mol. designing and the widely used composite tactics, new class of electrolytes with high-electrochem. performance for all-solid-state Li-ion batteries can be developed.

A new design strategy for high-performance organic cathode active materials for lithium-ion batteries is presented, which involves the assembly of redox-active organic mols. with a crystalline porous structure using mixed-stacked charge-transfer (CT) complexes. Hexahydroxytriphenylene was used as a donor mol. and 1,4,5,8,9,12-hexaazatriphenylene-2,3,6,7,10,11-hexacarbonitrile as an acceptor mol. to give a new porous CT complex (PCT-1) with a pseudo-hexagonal mixed columnar structure. X-ray diffraction measurements and sorption experiments demonstrated that the intercolumnar spaces in PCT-1 can incorporate various mols. accompanied by lattice expansion. A lithium metal battery containing PCT-1 as a cathode active material exhibited a high capacity of 288 mA h g-1 at 500 mA g-1, and this performance was attributed to a combination of the redox-active units and the porous structure of PCT-1.
