Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 401566-79-8, Name is 1-(3-Methyl-1-phenyl-1H-pyrazol-5-yl)piperazine, SMILES is CC1=NN(C2=CC=CC=C2)C(N3CCNCC3)=C1, belongs to piperidines compound. In a document, author is Lu, Chuanrui, introduce the new discover, SDS of cas: 401566-79-8.
Chemically stable poly(meta-terphenyl piperidinium) with highly conductive side chain for alkaline fuel cell membranes
Poly(arylene piperidine)s (PAPs) backbones, which do not contain unstable ether bonds, was synthesized by one-pot, metal-free superacid-catalyzed polymerization for anion exchange membranes (AEMs) preparation. Meta-terphenyl as a monomer of polymer to regulate the morphology and properties of AEM was also used due to its spatially torsional configuration instead of the recently reported linear structure of peta-terphenyl. Long flexible hydrophilic chains were grafted onto poly(meta terphenyl piperidinium) (m-PTP) backbone to form four cationic functionalized side chains, promoting efficient transfer of OH- and optimizing the hydrophilic/hydrophobic microphase separation structure. The resulting AEM shows a high ion conductivity of 164 mS/cm (mPTP-TFPE-21) at 80 degrees C. Furthermore, stable piperidine cation and long alkyl spacer chain contributed to the excellent alkali stability of m-PTP-TFPE-TQA membrane which shows only 11.67% and 12.73% degradation in ion conductivity and IEC, respectively, after soaking in 2 M NaOH at 80 degrees C for 1500 h. The peak power density of the H-2/O-2 single cell using m-PTP-TFPE-14 is 269 mW/cm(2) at a current density of 540 mA/cm(2) at 80 degrees C.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 401566-79-8 is helpful to your research. SDS of cas: 401566-79-8.
