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

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.

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. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).COA of Formula: C11H10O

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 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. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).COA of Formula: C8H10O2
