Author is Duan, Xiaoling; Wang, Cun-Wen; Wang, Tielin; Xie, Xiaolin; Zhou, Xingping; Ye, Yunsheng.

There are numerous metallic impurities in wet H3PO4, which causes striking neg. effects on industrial H3PO4 production The purification behavior of metallic impurities (Fe, Mg, Ca) from a wet H3PO4 solution employing the electroelectrodialysis (EED) technol. was studied. The cross-linked polysulfone anion-exchange membranes (AEMs) for EED were prepared using N,N,N’,N’-tetramethyl-1,6-hexanediamine (TMHDA) to achieve simultaneous crosslinking and quaternization without any cross-linkers or catalysts. The performance of the resulting membranes can be determined using quaternization reagents. When the molar ratio of trimethylamine/TMHDA/chloromethylated polysulfone is 3:1:1, the cross-linked membrane CQAPSU-3-1 exhibits lower H2O swelling and membrane area resistance than the noncross-linked membrane. The low membrane area resistance of CQAPSU-3-1 with long alkyl chains was obtained due to the hydrophilic-hydrophobic microphase separation structure formed by TMHDA. EED experiments with different initial H3PO4 concentrations of 0.52 and 1.07M were conducted to evaluate the H3PO4 purification of different AEMs. The EED experiments were more suitable for the purification of wet H3PO4 solution at low concentrations The H3PO4 concentration in the anode compartment could be increased from 0.52 to 1.04M. Through optimization, with an initial acid concentration of 0.52M, CQAPSU-3-1 exhibits an enhanced metallic impurity removal ratio of >72.0%, the current efficiency of >90%, and energy consumption of 0.48 kWh/kg. Therefore, CQAPSU-3-1 exhibits much higher purification efficiency than other membranes at a low initial H3PO4 concentration, suggesting its potential in H3PO4 purification application.

Synthetic Route of C10H24N2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine, is researched, Molecular C10H24N2, CAS is 111-18-2, about Synergistically integrated phosphonated poly(pentafluorostyrene) for fuel cells. Author is Atanasov, Vladimir; Lee, Albert S.; Park, Eun Joo; Maurya, Sandip; Baca, Ehren D.; Fujimoto, Cy; Hibbs, Michael; Matanovic, Ivana; Kerres, Jochen; Kim, Yu Seung.

Modern electrochem. energy conversion devices require more advanced proton conductors for their broad applications. Phosphonated polymers have been proposed as anhydrous proton conductors for fuel cells. However, the anhydride formation of phosphonic acid functional groups lowers proton conductivity and this prevents the use of phosphonated polymers in fuel cell applications. Here, we report a poly(2,3,5,6-tetrafluorostyrene-4-phosphonic acid) that does not undergo anhydride formation and thus maintains protonic conductivity above 200°C. We use the phosphonated polymer in fuel cell electrodes with an ion-pair coordinated membrane in a membrane electrode assembly. This synergistically integrated fuel cell reached peak power densities of 1,130 mW cm-2 at 160°C and 1,740 mW cm-2 at 240°C under H2/O2 conditions, substantially outperforming polybenzimidazole- and metal phosphate-based fuel cells. Our result indicates a pathway towards using phosphonated polymers in high-performance fuel cells under hot and dry operating conditions.

Preparation of CuO-BaTiO3 mixed oxide thin film by the decomposition of a self-assembled multibilayer film as a mol. template was studied. Also, CO2 sensing property of the resultant thin film was studied as a capacitive type sensor. The self-assembled bilayer film of few 1000 layers thickness can be obtained easily by casting an aqueous suspension consisting of dimethyldihexadecylammonium bromide (DC1-16), Cu(ClO4)2, Ba(TiO(C2O4)2), 2,6-dimethyl-3,5-heptadione (DHP), and polyvinyl alc. Divalent copper ion (Cu2+) which is associated with 2 DHP mols. was incorporated into the mol. bilayer film and BaTiO3 precursor exists at the interspace of mol. bilayer film by coordinating with polyvinyl alc. Upquenching the organic-inorganic film at 1173 K leads to the uniform film of CuO-BaTiO3 oxide mixture Although operating temperature shifted to higher temperature, the resultant film exhibits the capacitance change upon exposure to CO2. Consequently, the mixed oxide film of CuO-BaTiO3 prepared by the decomposition of multibilayer film was also an appropriate capacitive type CO2 sensor.
