Catalytic amination of diols with dimethylamine is a promising approach for the preparation of tetra-Me diamines. In this work, a series of Cu/ZnO/γ-Al2O3 catalysts were developed by co-precipitation and employed in the amination of 1,6-hexanediol (HDO) with dimethylamine (DMA) to N,N,N’,N’-tetramethyl-1,6-hexanediamine (TMHDA) in a fixed-bed reactor. Cu/ZnO/γ-Al2O3-20 exhibited remarkable catalytic performance. Nearly complete conversion of HDO was reached and 93% selectivity of TMHDA was obtained at 180°C. The excellent catalytic performance was attributed to the highly dispersion of Cu, which was promoted by doped ZnO. The results of characterizations (TEM, H2-TPR, XRD, XPS, etc.) indicated that doped ZnO could efficiently decrease the average particle size and improve the dispersion of Cu. The promoting effect could be ascribed to strong interaction between Cu and ZnO. The availability and effectiveness of Cu/ZnO/γ-Al2O3 catalyst offer a prospective way for the industrial production of tertiary diamines through amination of diols.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine(SMILESS: CN(C)CCCCCCN(C)C,cas:111-18-2) is researched.Recommanded Product: 2-Chloropyridine 1-oxide. The article 《Ionomer optimization for water uptake and swelling in anion exchange membrane electrolyzer: oxygen evolution electrode》 in relation to this compound, is published in Journal of the Electrochemical Society. Let’s take a look at the latest research on this compound (cas:111-18-2).

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.

Hierarchical aluminosilicate zeolites with uniform mesoporosity were successfully synthesized by one-stage crystallization under constant temperature with a novel single-head quaternary ammonium salt ([C18H37-N+(CH3)2-C6H12-N(CH3)2]Br-) as mesoporogen and structure-directing agent (SDA). Through precisely controlling the molar ratio of Si/Al and synthetic time, the mesoporous 3D wormhole framework (MCM-48) and crystalline microporous MFI structure were simultaneously constructed, revealed by a series of in-depth characteristic studies. Combining the advantages of the significantly improved diffusion from the mesoporous MCM-48 and the strong framework acidity of the crystalline microporous MFI zeolite, the hierarchical aluminosilicate zeolites exhibited outstanding catalytic activity with good reusability towards bulky aldol condensation compared with the conventional meso- or microporous zeolites.

Hierarchical titanium silicalite-1 nanosheets (HTS-1) were hydrothermally synthesized by using a bolaform surfactant [C6H13-N+(CH3)2-C6H12-N+(CH3)2-(CH2)12-O-(p-C6H4)2-O-(CH2)12-N+(CH3)2-C6H12-N+(CH3)2-C6H13] [OH-]4 as the structure-directing agent. The resultant zeolite particles possessed not only a superior interlayer stability but also a unique house-of-cards-like structure by the 90° rotational boundary connectivity of TS-1 nanosheets directed by the π-π stacking interaction from the biphenyl group in the bolaform surfactant as well as content controllability of coordinated Ti species in the zeolite framework. The obtained HTS-1 samples were used as catalysts for the epoxidation of bulky cyclic olefins (cyclohexene and cyclooctene) and exhibited improved performance and superior recyclability in comparison with the conventional solely microporous TS-1 (CTS-1) catalyst as well as the mesoporous TS-1 (MTS-1) catalyst directed by the com. organosilane surfactant TPOAC, due to their exoteric interlayered mesopores and enlarged external surface areas providing more accessible Ti active sites for the bulky mol. reactants. Moreover, the optimized Ti content for the HTS-1 catalysts was proposed by fully taking into account the conversion and turnover frequency (TOF) values. In addition, the recyclability and stability of the HTS-1 catalysts in the epoxidation reaction and the post fluoride treatment to enhance their hydrophobicity as well as epoxidation activity were further discussed.

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 Using a switchable water to improve sustainable extraction for oil sands by low-concentration surfactant solution. Author is Li, Xiaojiang; Wang, Li; Lu, Hongsheng; Wang, Na; Wang, Baogang; Huang, Zhiyu.

Surfactant extraction is the common method for treating oil sands. However, the recovery of traditional surfactant is difficult, and the oil emulsification phenomenon and generation of tailings are also caused easily. To develop the cleaner and sustainable approach for treating oil sands, a switchable water N, N, N’, N””-tetramethylhexanediamine (TMHDA) was used to improve extraction by surfactant sodium dodecyl benzene sulfonate (SDBS) solution with low concentration Here, the TMHDA-containing SDBS solution has CO2 switchability because of the electrostatic interaction between SDBS solution and TMHDA with CO2 response, and can be also emulsify reversibly n-heptane, diesel oil, even crude oil, providing the possibility for separating oil from oil sands. The effective extraction of oil sands is performed by 1 mM (less than critical micelle concentration (CMC)) SDBS solution combined with TMHDA, which was also demonstrated by thermogravimetric analyzer, scanning electron microscope and elemental anal. The residual oil content of oil sands is reduced to 0.515 wt% and 90.8% oil is removed by adding 0.15 g/mL TMHDA. Interestingly, oil is separated and fine sands is separated by introducing CO2, and the TMHDA-containing SDBS is recycled upon N2/65°C. According to the detection of interfacial tension and Fourier Transform IR Spectroscopy (FTIR), it is demonstrated that the improved oil removal is ascribed to the adsorption of SDBS on solid surface and the reduced oil-water interface tension by the addition of TMHDA. Based on the evaluation of economic and environmental value, this sustainable approach exhibits potential application for treating oil sands in practical industry.

Keywords: polyionene antimicrobial surface grafting; antimicrobial surfaces; grafted polymers; polyionenes; proadhesive surfaces; surface-polymerization. We’ll tell you more about this compound (cas:111-18-2).

Polyionenes (PI) with stable pos. charges and tunable hydrophobic spacers in the polymer backbone, are shown to be particularly efficient regarding antimicrobial properties. This effect can be modulated since it increases with the length of hydrophobic spacers, i.e., the number of methylene groups between quaternary ammoniums. Now, to further explore these properties and provide efficient antimicrobial surfaces, polyionenes should be grafted onto materials. Here a robust grafting strategy to covalently attach polyionenes is described. The method consisted in a sequential surface chem. procedure combining polydopamine coating, diazonium-induced polymerization, and polyaddition To the best of knowledge, grafting of PI onto surfaces is not reported earlier. All chem. steps are characterized in detail via various surface anal. techniques (FTIR, XPS, contact angle, and surface energy measurements). The antibacterial properties of polyionene-grafted surfaces are then studied through bacterial adhesion experiments consisting in enumeration of adherent bacteria (total and viable cultivable cells). PI-grafted surfaces are showed to display effective and versatile bacteriostatic/bactericidal properties associated with a proadhesive effect.

The article 《Task-specific deep eutectic solvents for the highly efficient and selective separation of H2S》 in relation to this compound, is published in Separation and Purification Technology. Let’s take a look at the latest research on this compound (cas:111-18-2).

Developing environmental benign and efficient solvents for the natural gas sweetening is of great significance to the development of green chem. However, there is no task-specific deep eutectic solvents (DESs) for H2S absorption so far. Herein, we have for the first time developed a series of task-specific DESs for the selective separation of H2S, in which quaternary ammonium salts with free tertiary amine groups are designed as hydrogen bond acceptors (HBAs) and azoles as hydrogen bond donors (HBDs). D., viscosity, and thermal decomposition temperature, as well as the solubility of H2S (0-1.0 bar), CO2 (0-1.0 bar), and CH4 (0-5.0 bar) were systematically determined NMR paired with theor. calculations are applied to characterize the interaction mechanism of H2S and DESs. A reaction equilibrium thermodn. model (RETM) with a 1:2 stoichiometric reaction mechanism was screened to correlate H2S solubility data. It is found that [C4-TMHDA][Cl]-Im could achieve up to 0.996 mol H2S per mol DES at 303.2 K and 1.0 bar. Moreover, the captured H2S can be easily stripped out at elevated temperature and reduced pressure, with negligible loss in H2S capacities during four absorption-desorption cycles. The results obtained in this work indicate that these DESs are promising candidates for efficient and selective separation of H2S and CO2 from natural gas. This work provides novel insights into the future design of high-performance task-specific DESs for the capture of H2S.

Synthetic Route of C10H24N2. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms.

Author is Zhong, Weiqiang; Chang, Yaoyao; Lin, Yaling; Zhang, Anqiang.

A series of linear hydrophilic cationic polymers with different charge d. and mol. weights were synthesized by one-step polymerization process. The effect of the hydrophobicity and mol. weights on the antifungal activity against Rhizoctonia solani (R. solani) and Fusarium oxysporum f. sp. cubense race 4 (Foc4) was assessed. The biotoxicity of the cationic polymers were evaluated based on their median lethal concentration (LC50) for zebrafish and silkworm and median LD (LD50) for Kunming mice. The results indicated that the balance between antifungal activity and biotoxicity could be well tuned by controlling the hydrophobic-hydrophilic balance. The min. inhibitory concentration (MIC) of PEPB10 and PEPB25 against R. solani were 160μg/mL and 80μg/mL, resp. And the LD50 for Kunming mice of PEPB10 and PEPB25 were more than 5000 mg/kg, which mean that PEPB10 and PEPB25 with high hydrophilicity show low toxicity and better selectivity for R. solani. The cationic polymers can kill the R. solani by damaging their membranes and exchanging the Ca2+ or/and Mg2+ cations of their membranes or cell wall. These results help to understand the antifungal mechanism of low-toxic polymeric quaternary ammonium salts and highlight their potential application as highly selective fungicidal agents for controlling plant diseases.

HPLC of Formula: 111-18-2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine, is researched, Molecular C10H24N2, CAS is 111-18-2, about Organisation of clay nanoplatelets in a polyelectrolyte-based hydrogel. Author is Hotton, Claire; Sirieix-Plenet, Juliette; Ducouret, Guylaine; Bizien, Thomas; Chenneviere, Alexis; Porcar, Lionel; Michot, Laurent; Malikova, Natalie.

We investigate the organization of clay nanoplatelets within a hydrogel based on modified ionenes, cationic polyelectrolytes forming phys. crosslinked hydrogels induced by hydrogen bonding and π-π stacking. Combination of small angle X-ray and neutron scattering (SAXS, SANS) reveals the structure of the polyelectrolyte network as well as the organization of the clay additives. The clay-free hydrogel network features a characteristic mesh-size between 20 and 30 nm, depending on the polyelectrolyte concentration Clay nanoplatelets inside the hydrogel organize in a regular face-to-face stacking manner, with a large repeat distance, following rather closely the hydrogel mesh-size. The presence of the nanoplatelets does not modify the hydrogel mesh size. Further, the clay-compensating counterions (Na+, Ca2+ or La3+) and the clay type (montmorillonite, beidellite) both have a significant influence on nanoplatelet organization. The degree of nanoplatelet ordering in the hydrogel is very sensitive to the neg. charge location on the clay platelet (different for each clay type). Increased nanoplatelet ordering leads to an improvement of the elastic properties of the hydrogel. On the contrary, the presence of dense clay aggregates (tactoids), induced by multi-valent clay counterions, destroys the hydrogel network as seen by the reduction of the elastic modulus of the hydrogel.
