The “”trade-off”” effect between hydroxide conductivity and dimensional stability is challenging issue for anion exchange membrane fuel cells (AEMFCs). In this study, the framework of UiO-66-NH2 is for the first time applied to anion exchange membranes (AEMs). The robust pore walls of UiO-66-NH2 with mech. and structural durabilities protect the membrane from the excessive swelling effects (a swelling ratio of 7%). In addition, the framework of UiO-66-NH2 is directly modified into (UiO-66-NH2)+Cl- as hydroxide conduction channels by anion stripping for the first time. A well-organized ion nanochannels is constructed by the in-situ self-assembly of N,N,N’,N’-tetramethyl-1,6-hexanediamine (TMHDA) and allyl bromide within the highly ordered pores of (UiO-66-NH2)+Cl-. The obtained QA@(UiO-66-NH2)+Cl- then incorporated into pristine membrane (QAPPO) to fabricate the novel multi-channel AEMs. The hydroxide conductivity of QA@(UiO-66-NH2)+Cl-/PPO is up to 123 mS·cm-1 at 80°, which is greatly improved compared to QAPPO pristine membrane.

The article 《Preparation of Silicalite-1 Nanosheets and its Application in Vapor-Phase Beckmann Rearrangement of Cyclohexanone Oxime》 in relation to this compound, is published in Integrated Ferroelectrics. Let’s take a look at the latest research on this compound (cas:111-18-2).

Silicalite-1 nanosheets catalyst with a hierarchical architecture was hydrothermally synthesized using [C18H37-N+(CH3)2-C6H12-N+(CH3)2-C6H13](Br)-2 as template. It has been studied systematically by investigating the influence of different synthesis parameters and crystallization kinetics under tumbling conditions. Highly crystalline silicalite-1 nanosheets with large external surface was obtained by regulating the crystallization time and the amount of water, template and the alkalinity It was examined as catalyst for vapor-phase Beckmann rearrangement of cyclohexanone oxime to caprolactam and exhibited an excellent catalytic performance and long catalytic lifetime. This can be attributed to nest silanol groups located on the large external surface of the nanosheets. Furthermore, the high mesoporosity of nanosheets shorten the diffusion path length and reduce coking deposition, which remarkably improve catalyst stability.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Direct Synthesis of Nanosheet-Stacked Hierarchical “”Honey Stick-like”” MFI Zeolites by an Aromatic Heterocyclic Dual-Functional Organic Structure-Directing Agent, published in 2021-06-16, which mentions a compound: 111-18-2, Name is N1,N1,N6,N6-Tetramethylhexane-1,6-diamine, Molecular C10H24N2, Formula: C10H24N2.

Soft template designing is the most promising strategy for the synthesis of zeolite nanosheets. MFI nanosheets directed by soft templates (containing long-chain alkyl groups or aromatic groups as hydrophobic component) can be found frequently. However, so far, MFI nanosheets synthesized by soft templates with aromatic heterocycle groups (e. g., s-triazine groups) are rare. Herein, a nanosheet-stacked hierarchical MFI zeolite (NSHM) has been synthesized by using a triply branched s-triazine-based surfactant as a bifunctional organic structure-directing agent. On the basis of a geometrical match relationship, a formation model has been proposed. Synthesized NSHM had abundant mesopores stacked by nanosheets and exhibited a high surface area (430 m2 · g-1). The 1 wt% Pd/NSHM attained a significant increase in yield of cyclohexanol/cyclohexanone mixture (from 66 to 85 %) in the oxidation of cyclohexane compared with Silicalite-1 and SBA-15 as supports.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Electrochemical performance and enhanced nitrate removal of homogeneous polysulfone-based anion exchange membrane applied in membrane capacitive deionization cell, published in 2020-12-15, which mentions a compound: 111-18-2, Name is N1,N1,N6,N6-Tetramethylhexane-1,6-diamine, Molecular C10H24N2, Safety of N1,N1,N6,N6-Tetramethylhexane-1,6-diamine.

This paper aims to investigate different strategies toward the enhancement of nitrate removal in a membrane capacitive deionization cell using different membrane functionalizing agents such as trimethylamine, triethylamine, and N,N,N’,N’-tetramethyl-1,6-hexanediamine as well as a double-layer, novel homogeneous polysulfone-based anion exchange membrane. The prepared membranes exhibited nitrate vs. chloride transport number ratio in the range of 0.96-1.52. The salt adsorption capacity for the NaNO3 feed was about 1.4-fold compared to that of using NaCl in case of triethylamine functionalized membrane under individual feeding solutions of 30 mL NaCl or NaNO3 during 30 min, and adsorption/desorption voltages of 1.6/0.0 V process conditions. At the same time, this parameter was about 1.2-fold weaker for the cell with a double-layer membrane. Based on the experiments, it can be inferred that the affinity toward nitrate could be promoted as the chain length of the alkyl group increases (i.e., increasing hydrophobicity of the groups). However, due to decrement in water uptake, the overall electrochem. performance of the membranes tended to weaken as the affinity toward nitrate increased. Results showed that the prepared membranes are suitable substitutions to conventional polystyrene-based ones utilized in membrane capacitive deionization cells.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called TEOS-modified Ni/ZSM-5 nanosheet catalysts for hydroconversion of oleic acid to high-performance aviation fuel: Effect of acid spatial distribution, published in 2020-01-01, which mentions a compound: 111-18-2, mainly applied to tetraethoxysilane nickel ZSM5 nanosheet catalyst; hydroconversion oleic acid aviation fuel spatial distribution, Application of 111-18-2.

Ni/ZSM-5 nanosheet catalysts with different Si/Al ratios were modified by chem. liquid deposition (CLD) of tetraethoxysilane (TEOS) to tailor their acid spatial distribution. Their catalytic performance was evaluated with the hydroconversion of oleic acid to aviation-fuel-range-alkanes (AFRAs) at different reaction temperatures and H pressures. The modified catalysts inherit the nanosheet structure with decreased external Bronsted acid concentration, especially the strong one. External Bronsted acid sites mainly favor the cracking of the deoxygenated products (C17/C18). Internal Bronsted acid sites mainly enhance the isomerization of the linear AFRAs. The catalytic activity of the external Bronsted acid sites was more sensitive to reaction temperature than that of the internal ones. The deoxygenation and cracking reactions were also more sensitive to H pressure compared to the isomerization reaction. High AFRA selectivity of 51.4% as well as high iso/n-alkanes ratio of 1.7 were achieved at 250° and 10 bar over NS200(1).

Author is Zhao, Tuo; Long, Chuan; Wang, Zhiqian; Zhu, Hong.

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.

Synthetic Route of C10H24N2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate.

Author is Sung, Seounghwa; Mayadevi, T. S.; Min, Kyungwhan; Lee, Junghwa; Chae, Ji Eon; Kim, Tae-Hyun.

Crosslinked poly (2,6-dimethyl-1,4-phenylene oxide) (PPO) using hydrophilic crosslinkers that contain ethylene oxide (EO) were prepared as novel anion exchange membranes (AEMs), and the effect of crosslinker EO length was systematically investigated. The physicochem., morphol. and electrochem. properties of the corresponding AEMs were also compared against the membrane prepared from a typical hydrophobic alkyl-type crosslinker. The ethylene oxide crosslinker helped to form ion clusters and to enhance the water-holding capacity of the corresponding AEMs, which promoted high conductivity both in water and in 95% room humidity conditions, while maintaining high physicochem. stability. However, it was also found that the presence of a long ethylene oxide as a crosslinker may induce polymer crystallinity, which reduces both conductivity and the alk. stability of the corresponding crosslinked membranes. The effect of ethylene oxide chain length on the morphol., electrochem. and physicochem. properties, were also investigated. The xBEO-PPO membrane, having bis(ethylene oxide) (BEO) as a crosslinker, showed the highest conductivity of 131.96 mS/cm in water at 80 °C, and 55.21 mS/cm in 95% RH at 80 °C; this was owing to its crystalline nature. The single-cell performance of 444 mW/cm2 peak power d., was also obtained from the xBEO-PPO membrane.
