Zeng, Xu; Akiyama, Takuya; Yokoyama, Tomoya; Matsumoto, Yuji published an article in 2020, the title of the article was Contribution of the γ-hydroxy group to the β-O-4 bond cleavage of lignin model compounds in a basic system using tert-butoxide.HPLC of Formula: 91-16-7 And the article contains the following content:

The most common non-phenolic β-O-4-type lignin model compounds with or without the γ-hydroxymethyl group (C6-C3- or C6-C2-type, resp.) were treated in a 0.5 mol/L potassium tert-butoxide in DMSO solution at 30°C to examine the effects of presence of the group. The β-O-4 bond of the C6-C3-type cleaved more rapidly than the C6-C2-type, indicating that the γ-hydroxy group contributes to the cleavage, in contrast to their reactions in alk. pulping processes. Furthermore, the β-O-4 bond of the threo isomer of the C6-C3-type cleaved more rapidly than that of the erythro isomer. This result can be attributed to the fact that the erythro isomer has the hydrogen bond between a generated alkoxide and the other hydroxy group at its α- and γ-positions in its most-preferential conformer, interfering with the β-O-4 bond cleavage. It was also suggested in treatments of their methyl-etherified derivatives at the α- or γ-hydroxy group that the contribution of the γ-hydroxy group of the threo isomer is greater than that of the erythro isomer. Detailed examination of the distribution profile of reaction products supported this greater contribution of the γ-hydroxy group of the threo isomer. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).HPLC of Formula: 91-16-7

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. And the article contained the following:

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. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Quality Control of 2-Methylanisole

On May 9, 2022, Kim, Seulgi; Park, In-Hyeok; Lee, Eunji; Jung, Jong Hwa; Lee, Shim Sung published an article.COA of Formula: C8H10O2 The title of the article was Metallosupramolecules of Pillar[5]arene with Two Flexible Thiopyridyl Arms: A Heterochiral Cyclic Dimer and Organic Guest-Assisted Homochiral Poly-Pseudo-Rotaxanes. And the article contained the following:

The formation of a cyclic dimer complex (1) and a poly-pseudo-rotaxane (2) of a racemic A1/A2-thiopyridyl pillar[5]arene (rac-L) with different chirality is reported. A one-pot reaction of rac-L with HgCl2 afforded a heterochiral cyclic dimer complex, [Hg2(pR-L)(pS-L)Cl4]·8CH2Cl2 (1), in which two Hg2+ atoms and one (pR-L)/(pS-L) enantiomeric pair form a [2:2] metallacycle via a metal coordination-based cyclization. Interestingly, the same reaction in the presence of the linear dinitrile guest, CN(CH2)8CN (G), yielded a one-dimensional poly-pseudo-rotaxane, {[Hg(G@pR-L)Cl2][Hg(G@pS-L)Cl2]}n (2), probably due to the rigidified ligand structure resulting from the dinitrile guest (G) threading. In 2, pR-L and pS-L generate two separated homochiral poly-pseudo-rotaxanes in a crystal. Both products are new members of the pillararene-derivative family. This study improves our understanding of self-assembly in nature and leads to this approach being an engineering tool for the construction of mech. interlocked supramols.

On July 15, 2009, Voepel, Jens; Edlund, Ulrica; Albertsson, Ann-Christine published an article.Computed Properties of 929-37-3 The title of the article was Alkenyl-functionalized precursors for renewable hydrogels design. And the article contained the following:

A library of crosslinking chemistries for the hydrogel synthesis based on the hemicellulose acetylated galactoglucomannan (AcGGM) has been developed, demonstrated, and evaluated. A three-step route was elaborated including (1) the carbonyldiimidazole activation of primary hydroxylated vinylic mols. such as acrylates, vinyl alcs., and vinyl ethers, (2) the covalent coupling of the alkenyl precursors to the polysaccharide backbone hydroxyls, and (3) the radical crosslinking of pendant vinyl functionalities affording a hydrophilic network. Crosslinking strategies explored include redox initiation and photo initiation, with an effort to adapt the suggested synthesis routes to benign conditions. The different functionalization strategies were shown to influence the resulting gel’s properties. Varying the crosslinking media was found to be a strong tool to tune the properties of the gels. Modifications were in all cases verified by means of NMR and FTIR, and the gels were characterized with respect to swelling capacity and rheol. parameters. It was shown that by adjusting the synthesis parameters, the resulting properties of the AcGGM gels could be custom-made for a given performance. © 2009 Wiley Periodicals, Inc.

On August 1, 2022, Li, Zhen; Fu, Teng; Lu, Jia-Hui; He, Jie-Hao; Li, Wen-Da; Liu, Bo-Wen; Chen, Li; Wang, Yu-Zhong published an article.COA of Formula: C11H10O The title of the article was Ultra-high fire-safety unsaturated polyesters enabled by self-assembled micro/nano rod from Schiff base, diphenylphosphinyl group and nickel (II) metal. And the article contained the following:

As one of the most flammable common com. resins, high flammability and heat/smoke release characteristics of unsaturated polyesters (UP) lead to severe casualties and irreparable property loss. To solve these problem, a flame-retardant approach via the multiple synergic effects of promoting char-ability, phys. shielding heat/mass transfer, and quenching small mol. fragments in burning is proposed. Herein, a novel micro/nano rod flame retardant SDPPNi, composed of diphenylphosphinyl groups, Schiff base and Nickel (II), are synthesized by self-assembly based on the coordination reactions. The UP with 25 wt% SDPPNi (UP/SDPPNi25), shows quite excellent fire-safety performance, and its limiting oxygen index is as high as 38.0%, showing extremely high flame retardant efficiency. Meanwhile, its peak heat release rate, total heat release, fire growth rate, and maximum smoke d. (Dsmax) values are significantly reduced by 69%, 40%, 72%, and 42%, resp. During burning, the SDPPNi promotes UP to form compact char layers composed of pyridine derivatives, phosphoric-oxygenic compounds, and nickel-oxides, inhibiting the heat and mass transfer. Meanwhile, the SDPPNi also releases phosphoros-containing volatiles that can capture some small mol. fragments and break off the chain reaction of combustion. Therefore, a state-of-art strategy is proposed to endow UP resins with ultra-high fire-safety performance.

On June 1, 2001, Ram, M. K.; Sarkar, N.; Bertoncello, P.; Sarkar, A.; Narizzano, R.; Nicolini, C. published an article.HPLC of Formula: 146370-51-6 The title of the article was Fabrication and characterization of poly[(2-methoxy-5-(2′-ethyl-hexyloxy)phenylene vinylene] (MEH-PPV) Langmuir-Schaefer films and their application as photoelectrochemical cells. And the article contained the following:

The Langmuir monolayer behavior of poly[2-methoxy-5-(2′-ethyl-hexyloxy)phenylenevinylene] (MEH-PPV) conducting polymer in a subphase containing various anions was investigated at the air-water interface. The Langmuir-Schaefer (LS) films were prepared in deionized water that showed the min. area per mol., and were found to be essential for the formation of Langmuir monolayer at the air-water interface of MEH-PPV conjugated polymer. The LS films of MEH-PPV were investigated by using UV-VIS absorption, electrochem. and at. force microscopic techniques. A uniform deposition of monolayers was shown by optical technique, whereas a higher number of monolayers resulted in the tiny island morphol. in MEH-PPV LS films. The influence of concentration of anions on the redox properties of the LS films was studied by cyclic voltammetric measurements. The nature of anions in electrochem. investigation revealed the significant changes in the redox properties of the MEH-PPV LS films. The photoelectrochem. current transient of MEH-PPV LS films was compared with those obtained by the solution cast technique. This work also focused on the influence of the nature of the electrolytes, the applied potential, the type of the film and the presence of dissolved oxygen on the photoelectrochem. properties of MEH-PPV conducting polymer.

On June 26, 2012, Liang, Siwei; Choi, U. Hyeok; Liu, Wenjuan; Runt, James; Colby, Ralph H. published an article.Quality Control of 2-(2-(Vinyloxy)ethoxy)ethanol The title of the article was Synthesis and Lithium Ion Conduction of Polysiloxane Single-Ion Conductors Containing Novel Weak-Binding Borates. And the article contained the following:

Three borate monomers: lithium triphenylstyryl borate (B1), a variant with three ethylene oxides between the vinyl and the borate (B2) and a third with perfluorinated Ph rings (B3) were synthesized and used to prepare polysiloxane ionomers based on cyclic carbonates via hydrosilylation. B1 ion content variations show maximum 25 °C conductivity at 8 mol %, reflecting a trade-off between carrier d. and glass transition temperature (Tg) increase. Ethylene oxide spacers (B2) lower Tg, and increase the dielec. constant, both raising conductivity Perfluorinating the four Ph rings (B3) lowers the ion association energy, as anticipated by ab initio estimations This increases conductivity, a direct result of 3 times higher measured carrier d. The � kJ/mol activation energy of simultaneously conducting ions is less than half that of ionomers with either sulfonate or bis(trifluoromethanesulfonyl) imide anions, suggesting that ionomers with weak-binding borate anions may provide a pathway to useful single-ion Li+ conductors, if their Tg can be lowered.
