Computed Properties of C10H24N2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine, is researched, Molecular C10H24N2, CAS is 111-18-2, about Partially fluorinated, multication cross-linked poly(arylene piperidinium) membranes with improved conductivity and reduced swelling for fuel cell application.

As an important component in alk. membrane fuel cells, anion exchange membrane (AEM) often suffers from the tradeoff between ionic conductivity and chem./dimensional stability. We herein report a partially fluorinated poly(arylene piperidinium) AEM with multication cross-links, which was synthesized by copolymerizing 1,1,1-trifluoroacetone, N-methyl-4-piperidone, biphenyl, and subsequent crosslinking with N1, N6-bis(6-bromohexyl)-N1, N1, N6, N6-tetramethylhexane-1,6-diammonium bromide. The resultant AEM exhibited an excellent OH- conductivity of 148.7 mS cm-1 at 80 °C (IEC = 2.9 mmol g-1) due to the multication structure, which may promote microphase separation to produce wide ion-conducting channels. Compared with those without partial fluorination, the fluorinated AEM showed lower swelling ratio (33% vs. 58% at 80 °C). The ionic conductivity of the AEM remained by 85% after it was treated 1700 h in 1 M NaOH at 80 °C. In addition, the H2/O2 fuel cell assembled with the AEM yielded a peak power d. of 208 mW cm-2 at 60 °C. Our work successfully demonstrates the synergistic effect of partially fluorinated backbone and multication cross-linked structure to inhibit membrane swelling while keeping high conductivity; it is beneficial for better balancing AEM conductivity and robustness. Partially fluorinated poly(arylene piperidinium) AEM with multication cross-links. The fabricated membrane showed higher conductivity and much lower swelling compared with its non-fluorinated counterpart. [graphic not available: see fulltext]

HPLC of Formula: 111-18-2. 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 Ionomer optimization for water uptake and swelling in anion exchange membrane electrolyzer: oxygen evolution electrode. Author is Huang, Garrett; Mandal, Mrinmay; Hassan, Noor Ul; Groenhout, Katelyn; Dobbs, Alexandra; Mustain, William E.; Kohl, Paul A..

H2O electrolysis using an anion conductive, solid polymer electrolyte is an attractive method for point-of-use H production Recent advances in catalysts and anion exchange membranes (AEM) have made alk. devices increasingly competitive with their acidic counterparts. However, less attention was paid to the anion conductive ionomers (ACI) used in the fabrication of electrodes for AEM electrolyzers. The ACI contributes to ion conduction between the catalyst and bulk electrolyte and serves as a binder for adhering the catalyst to the gas diffusion layer and AEM. Ionic conductivity, H2O uptake and ionomer swelling are critical properties for electrode performance. High ion exchange capacity (IEC) in the ionomer is desired for reduced electrode resistance, however, it can lead to excess H2O uptake (WU) and disruptive ACI swelling. Poly(norbornene)-based ionomers were synthesized, characterized and used to fabricate O evolving anodes for low-temperature AEM H2O electrolysis. The IEC of the ionomers (0 to 4.73 meq g-1) was adjusted by controlling the ratio of ion conducting to nonion conducting norbornene monomers in the ACI tetrablock copolymers. Low conductivity ionomers yield the best-performing O evolution electrodes, in the absence of ACI polymer crosslinking because they do not experience excessive H2O swelling. Light crosslinking within the anode ACI was used as a means to independently lower WU of the ionomer without compromising ionic conductivity This control over H2O swelling allows higher ionic conductivity within the ACI to be used in H2O-fed electrolyzer applications. Other methods of H2O management were compared including the use of hydrophobic additives and adjustment of the ionomer concentration in the electrode. The cell performance greatly benefits from a highly conductive ionomer in the O evolution reaction electrode if the WU is managed.

Keywords: manganese oxide modified nanosheet ZSM5 zeolite nanosheet catalyst; methanol reaction propylene synthesis manganese oxide modified ZSM5 zeolite.They researched the compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine( cas:111-18-2 ).Formula: C10H24N2.

In addition, there is a lot of other information about this compound (cas:111-18-2) here.

Hydrothermally modified nanosheet ZSM-5 zeolite by directly using MnOx nanoparticles was carried out and this substantially offered a high performance catalyst for methanol to propylene (MTP) reaction. The properties of as synthesized ZSM-5 nanosheets with different MnOx amounts (NS-x) were compared with ZSM-5 nanosheets modified by impregnation method (IM-0.5) and phys. mixed method (PM-0.5), resp. The initial state of MnOx nanoparticles was close to Mn2O3 with 20 nm in size. XRD, H2-TPR and XAFS results confirmed under high temperature hydrothermal condition, the Mn2O3 nanoparticles disaggregated into Mn2O3 clusters and entered the framework defects of nanosheet zeolite with high dispersion. IR spectra of hydroxyl groups (OH-IR) showed that the Mn2O3 clusters were bonded with silanol defects both on the surface and inside zeolite, which substantially increased the stability of Mn2O3 clusters and healed the framework defects. In contrast, the Mn species in the impregnated sample was close to the co-existence of Mn2+ ions and MnO2 nanoparticles with 2-3 nm, no interaction between Mn species and Si-OH group was determined Notably, the typical sample (NS-0.5) with MnOx cluster modification performed much higher propylene selectivity and catalytic stability (∼52%, 240 h, WHSV = 3 h-1), while the conventional IM-0.5 and PM-0.5 showed poor propylene selectivity (48, 46%) and catalytic stability (166 h, 133 h) in MTP reaction. The excellent result should be attributed to the subtle control of external strong acid and the less structural defects, due to specific existence of bonded Mn2O3 clusters.

In addition, there is a lot of other information about this compound (cas:111-18-2) here.

As a key component of anion exchange membrane fuel cells (AEMFCs), anion exchange membranes (AEMs) have been investigated in the last decades. Herein, a series of multication cross-linkers were introduced into side-chain-type poly(p-terphenyl isatin) to develop high-performance and long-term stable AEMs. Addnl., the effects of the hydrophilic cross-linker length on the membrane performance were systematically investigated. The resulting cross-linked membranes possess a low swelling ratio (<18% at 80 °C) and high tensile strength (51.1-58.3 MPa). Notably, the cross-linker length influences the AEM internal morphol. With hexyl as the spacer between backbones and cation groups in the cross-linker, 0.9q-PTI-6C exhibits the highest hydroxide ion conductivity of 118.5 mS/cm at 80 °C, which is ascribed to well-developed ion channels. Furthermore, alkyl spacer chains and cross-linked networks contribute to the excellent alkali stability of membranes. After immersion in 2 M NaOH for 1200 h at 80 °C, 0.9q-PTI-8C only shows 11 and 12.7% losses in ion conductivity and ion exchange capacity (IEC), resp. The fuel cell fabricated using 0.9q-PTI-6C can achieve the maximum power d. of 310 mW/cm2 at 80 °C.
