In this research, series of PVDF microporous films with various polymer concentrations and thickness were prepared through thermally-induced phase separation in air condition with di-Ph carbonate as the diluent. Effects of polymer concentration and film thickness on the formation kinetics of microporous structure of PVDF thin films were in situ investigated via TII technique. The instantaneous heat conduction inside the films during film formation was also evaluated. Two types of parameter models were adopted in order to disclose the time and location dependence of TIPS film solidification kinetics, resp. Hierarchical microstructures, crystallization behavior and thermal properties of the TIPS films were also characterized by SEM, DSC, and TGA, resp. The current study could supply an insight into the fabrication of PVDF microporous films with target microstructure and desirable performance. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Application In Synthesis of Diphenyl carbonate).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Application In Synthesis of Diphenyl carbonate

Well-defined Cp*Co(III)-catalyzed Hydrogenation of Carbonates and Polycarbonates was written by Dahiya, Pardeep;Gangwar, Manoj Kumar;Sundararaju, Basker. And the article was included in ChemCatChem in 2021.Computed Properties of C13H10O3 The following contents are mentioned in the article:

The authors herein report the catalytic hydrogenation of carbonates and polycarbonates into their corresponding diols/alcs. using well-defined, air-stable, high-valent cobalt complexes. Several novel Cp*Co(III) complexes bearing N,O-chelation were isolated for the first time and structurally characterized by various spectroscopic techniques including single crystal X-ray crystallog. These novel Co(III) complexes have shown excellent catalytic activity to produce value added diols/alcs. from carbonate and polycarbonates through hydrogenation using mol. hydrogen as sole reductant or i-PrOH as transfer hydrogenation source. To demonstrate the developed methodol.’s practical applicability, the authors have recycled the bisphenol A monomer from compact disk (CD) through hydrogenation under the established reaction conditions using phosphine-free, earth-abundant, air- and moisture-stable high-valent cobalt catalysts.

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Computed Properties of C13H10O3

Lipase-catalyzed ring-opening copolymerization of macrocycles for diselenide-functionalized long-chain polycarbonate: Synthesis, kinetic process and ROS responsiveness was written by Li, Siqi;Ma, Xiaotong;Li, Ruizhi;Sun, Chuanhao;Hu, Jieni;Zhang, Yan. And the article was included in Reactive & Functional Polymers in 2022.Reference of 102-09-0 The following contents are mentioned in the article:

Herein, the lipase-catalyzed ring-opening copolymerization of the diethylene diselenide carbonate dimer (SeC) with its analog macrocycle (1,3,12,14-Tetraoxacyclodocosane-2,13-dione, TDC) was explored, and the small-ring carbonate (TMC) was used as control. The structure and composition of the diselenide-functionalized long-chain polycarbonates were confirmed by NMR and FTIR. The ¹³C NMR and ⁷⁷Se NMR showed that the copolymers observed random sequence. Moreover, the kinetic process of TDC + SeC copolymerization demonstrated a faster polymerization rate and higher conversion of SeC in comparison with TMC + SeC. Besides, the copolymers exhibited ROS-responsive behaviors when exposed to the oxidizing environment owing to the diselenide groups, which was confirmed by UV-vis, DLS and TEM. Therefore, the ROS responsiveness facilitated potential application for the diselenide-functionalized copolymers. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Reference of 102-09-0).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Reference of 102-09-0

Dielectric enhancement over a broad temperature by nanofiller at ultra-low volume content in poly(ether methyl ether urea) was written by Zhang, Tian;Chen, Xin;Zhang, Qiyan;Zhang, Q. M.. And the article was included in Applied Physics Letters in 2020.Computed Properties of C13H10O3 The following contents are mentioned in the article:

This Letter studies the dielec. responses of nanocomposites of poly(ether Me ether urea) (PEMEU) with alumina nanofillers at less than 0.7% volume loading (0.7 volume %). The results show that the dielec. constant K of PEMEU nanocomposites is enhanced by the nanofillers. The enhancement peaks at 0.33 volume % nanofiller loading, from K = 3.9 of neat polymer to K = 5.5 of nanocomposites from room temperature to 200°C, above the glass transition (âˆ?50°C) of the polymer. Except for an enhanced dielec. constant, the nanocomposite maintains a low dielec. loss and a high breakdown strength of 500 MV/m at room temperature and 300 MV/m at 150°C, resp. Thus, the nanocomposite with 0.33 volume % nanofillers delivers discharged energy densities of 6.5 J/cm³ at room temperature and 2 J/cm³ at 150°C with better than 90% charge/discharge efficiency, 40% higher than the neat polymer.

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Computed Properties of C13H10O3

And the article was included in ACS Applied Materials & Interfaces in 2021.Application In Synthesis of Diphenyl carbonate The following contents are mentioned in the article:

A new kind of biobased material named lignin-containing polyhydroxyurethane (LPHU) is prepared from bis(6-membered cyclic carbonate) (BCC), dimer fatty diamine, and lignin for the first time. The preparation strategy is isocyanate-free, solvent-free, and catalyst-free, representing a green and environmentally friendly method to access polyurethane (PU)/lignin composites. The resultant LPHUs possess dual networks: a dynamic covalent network and a hydrogen bonding network, exhibiting superior mech. strength, high thermal stability, excellent reprocessability/recyclability, and smart properties such as shape memory and self-healing. Potential application investigations indicate that the resultant LPHUs can be not only used for smart packaging label fabrication for heat-sensitive commodities but also further combined with natural cellulose paper to prepare paper-based electromagnetic shielding materials with high mech. performance.

Application of a novel cavity nucleating agent based on cyclodextrin in polymer foaming materials and in situ visual injection moulding study was written by Zhou, Yuhui;He, Li;Gong, Wei. And the article was included in Journal of Materials Science in 2021.Formula: C13H10O3 The following contents are mentioned in the article:

In this study, β-cyclodextrin nanosponges were synthesized using organic carbonates, namely gelatinous β-cyclodextrin nanosponges (NJ) and vitreous β-cyclodextrin nanosponges (BL). The ‘constructed’ porous structures were characterized by SEM. NJ and BL with different cavity structures as heterogeneous nucleation agents were selected for the polypropylene and polylactic acid foaming injection molding processes. The obtained exptl. results showed that NJ significantly reduced nucleation energy barrier and thus exhibited the highest nucleation efficacy. The nucleation mechanism was explored via a combination of the classical nucleation theory and in situ visual injection molding anal. In a word, the current work provided an insight into the structure-nucleating efficiency relationship for porous particles and highlighted the importance of the construction of porous structures in the organic nucleating agents to improve the polymeric foaming performances. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Formula: C13H10O3).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Formula: C13H10O3

Anionic ring-opening polymerization behavior of trans-cyclohexene carbonate using metal tert-butoxides: Construction of living anionic ring-opening polymerization by lithium tert-butoxide was written by Kawamoto, Masato;Mori, Yasuyuki;Tsuge, Akihiko;Endo, Takeshi. And the article was included in Journal of Polymer Science (Hoboken, NJ, United States) in 2022.Recommanded Product: 102-09-0 The following contents are mentioned in the article:

Anionic ring-opening polymerization (ROP) behavior of trans-cyclohexene carbonate (CHC) using metal alkoxides as initiators was investigated. As a result, lithium tert-butoxide-initiated ROP of CHC with a high-monomer concentration (10 M) at low temperature (-15 to -10°C) proceeded to afford a poly(trans-cyclohexene carbonate) (PCHC) without undesired side reactions such as mainly backbiting. The suppression of side reactions enables the control of the mol. weight (M_n = 2400-6100) of PCHC with low molar-mass dispersity values (M_w/M_n = 1.16-1.22). Furthermore, by increasing the feed ratio of the monomer to the initiator, the mol. weight increases proportionally, indicating a controllable polymerization The results of a matrix-assisted laser desorption/ionization time-of-flight mass spectrometry anal., a kinetic study, and a chain extension experiment suggested a living nature of this ROP using lithium tert-butoxide. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Recommanded Product: 102-09-0).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

FGF19 signaling through the FGFR4/β-klotho receptor complex has been shown to be a key driver of growth and survival in a subset of hepatocellular carcinomas, making selective FGFR4 inhibition an attractive treatment opportunity. A kinome-wide sequence alignment highlighted a poorly conserved cysteine residue within the FGFR4 ATP-binding site at position 552, two positions beyond the gate-keeper residue. Several strategies for targeting this cysteine to identify FGFR4 selective inhibitor starting points are summarized which made use of both rational and unbiased screening approaches. The optimization of a 2-formylquinoline amide hit series is described in which the aldehyde makes a hemithioacetal reversible-covalent interaction with cysteine 552. Key challenges addressed during the optimization are improving the FGFR4 potency, metabolic stability, and solubility leading ultimately to the highly selective first-in-class clin. candidate roblitinib.

A review. This review is dedicated to the state-of-the art routes used for the synthesis of CO₂-based (a)cyclic carbonates and polycarbonates from alc. substrates, with an emphasis on their resp. main advantages and limitations. The first section reviews the synthesis of organic carbonates such as dialkyl carbonates or cyclic carbonates from the carbonation of alcs. Many different synthetic strategies have been reported (dehydrative condensation, the alkylation route, the “leaving group” strategy, the carbodiimide route, the protected alcs. route, etc.) with various substrates (mono-alcs., diols, allyl alcs., halohydrins, propargylic alcs., etc.). The second section reviews the formation of polycarbonates via the direct copolymerization of CO₂ with diols, as well as the ring-opening polymerization route. Finally, polycondensation processes involving CO₂-based di-Me and di-Ph carbonates with aliphatic and aromatic diols are described. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Synthetic Route of C13H10O3).

Preparation and characterization of β-cyclodextrin nanosponges and study on enhancing the solubility of insoluble nicosulfuron was written by Liu, Xiaofang;Li, Wei;Xuan, Guangshan. And the article was included in IOP Conference Series: Materials Science and Engineering in 2020.Safety of Diphenyl carbonate The following contents are mentioned in the article:

Nicosulfuron (NSF) is a water-insoluble and unstable sulfonylurea herbicide, which is mainly used in the treatment of stems and leaves after the corn seedling stage. Nanosponges (NS) have more interaction sites and higher drug encapsulation capabilities. In this paper, three kinds of β-cyclodextrin nanosponges (CDNS) were prepared by crosslinking β-cyclodextrin with di-Ph carbonate (DPC), pyromellitic dianhydride (PMDA) and epichlorohydrin (EP), resp. The NSF-loaded CDNS were characterized by TEM, FTIR, DSC, TGA and XRD. The solubility, stability and biol. activity of NSF were studied. The results showed NSFEP-CDNS could significantly enhance the solubility of NSF. In vitro release test, the cumulative release of NSF-EP-CDNS was 90.11%. Compared with pure NSF and NSF oil suspension, NSF-EP-CDNS had the strongest inhibitory effect on acetolactate synthase (ALS). In conclusion, CDNS have beneficial effects on the solubility, stability and biol. activity of NSF.

Polyesters are important plastics, with monomers linked by ester moieties. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Safety of Diphenyl carbonate
