NEXAR (TM)-coated hollow fibers for air dehumidification

Air conditioning is one of the essential requirements for households as well as work stations. Dehumidification in air conditioning is the highest energy-consuming component, where membranes could play a crucial role. In this work, we propose the coating of NEXAR (TM), a commercial pentablock copolymer in tetrahydrofuran on polyetherimide hollow fiber support for separation of water vapor from humidified air. The block copolymer in tetrahydmfuran forms a lamellar/parallel cylindrical structure separated by equidistance during the morphological transformation process giving its unique characteristics with higher water vapor transfer efficiency. Both vacuum and sweep gas modes of membrane dehumidification strategies are investigated along with the detailed study of the morphological transformation process under a controlled environment, which is supported by comprehensive scanning electron microscopic and atomic force microscopic imaging. The membrane has shown water vapor permeance up to 9089 GPU with water vapor to nitrogen selectivity up to 3870. The membrane can reduce the relative humidity from 80% to 41% proving one of the competitive materials for membrane dehumidification.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 104-61-0. Computed Properties of C9H16O2.

Determination of the molecular size from measurements of vapour pressure of binary liquid mixtures. Theory, experiments and quantum chemical calculations

In the present work we focus on some fundamental organic solvents. The total and partial vapour pressure of 30 binary systems made of hexane, cyclohexane, and benzene with 10 organic molecules, namely chloroform (Chl), chlorobenzene (Cl-Ben), tetrahydrofuran (THF), dichloromethane (DCM), acetone (Ac), ethanol (Et0H), N, N-dimethylformamide own, methanol (MeOH), acetonitrile (MeCN) and dimethylsulphoxide (DMSO), were measured using the method developed by Sameshima. A simple electrostatic model was derived to express the change of the Helmholtz free energy as a function of dielectric properties of the binary mixtures, as well as the dielectric constant, dipole moment, dipole polarizability, and radius of a spherical cavity hosting the aforementioned 10 organic molecules. Through measurements of the partial vapour pressure of these 10 organic liquids, the size of the cavity was extracted, which approximates their molecular size. The molecular size obtained from the experiments exhibits a good agreement with the results as obtained from the cavity size calculated using the Polarizable Continuum Model (PCM). The partial vapour pressure of some compounds such as Ac, DMF, DMSO, and MeCN presented severe deviation from the Raoult law. The intermolecular interaction among the molecules of each compound was believed to take responsibility for their exceptional behaviours in vapour pressure. (C) 2020 Elsevier B.V.

STRUCTURE OF A Pd-ORGANIC PARAMAGNETIC

By the interaction of 2-bromo-4,4,5,5-tetramethyl-2-imidazoline-3-oxide-1-oxyl (NN-Br) with tetrakis(triphenylphosphine)palladium(0) a new paramagnetic palladium-organic compound [Pd(NN)(PPh3)(2)Br] is synthesized. The crystal structure of its tetrahydrofuran solvate is determined by X-ray diffraction. The obtained data allow us to expect that the effective Pd-C bond eclipsing by phenyl rings deactivates the compound in a cross-coupling reaction with aryl halides and provides its high kinetic stability under normal conditions. Magnetochemical studies show the presence of weak antiferromagnetic exchange interactions between spins of paramagnetic [Pd(NN)(PPh3)(2)Br].

Effective Utilization of Coal Processing Waste: Separation of Low Ash Clean Coal from Washery Rejects by Hydrothermal Treatment

Handling and disposal of high volume of fine coal tailings is a biggest challenge for coal washeries. Separation of clean coal by density separation and flotation shows limited yields of 23-28% and 13-14% respectively. Chemical leaching process has a challenge with the formation of insoluble salts. The present investigation aimed to separate clean coal by a combination of chemical-physical separation technique, i.e. alkaline hydrothermal process followed by density separation. Hydrothermal extraction of humic substance causes dissociation of coal aggregated structure (Mineral-Maceral-Pore structure), thus improves the separation. Experiments performed as per design of experiments and reduced design of experiments, where 100 mu particle size, 50% (w/w) pulp density, 4.5% KOH (w/w), and 140 degrees C reaction temperature found to be optimum, at which 16.2% ash clean coal at 40.7% yield and humic acid by-product at 18.3% yield were obtained. Use of swelling agent such as tetrahydrofuran shown negative impact on clean coal recovery. Material balance and cost data were presented to show the techno-commercial viability of this technology.

Evaluation of halogen chain-end functionality in 2-bromo-2-methylpropanoate esters of poly(oxyalkylene) polymers by MALDI-TOF spectroscopy

Esters of 2-bromo-2-methylpropanoate of poly(oxyalkylene) polymers such as poly(ethylene glycol) or alpha-methyl poly(ethylene glycol) were prepared in high yields and characterized by spectroscopic and chromatographic methods (NMR, FT-IR, mass spectroscopy and SEC). The halogen chain-end group in the poly(oxyalkylene) bromine-terminated esters was characterized by MALDI-TOF MS. The effect of the solvents (methanol or tetrahydrofuran) and the cationic agents such as silver trifluoroacetate (AgTFA), silver trifluoromethanesulfonate (AgTFS) and sodium trifluoroacetate (NaTFA) on the mass spectra was studied. Analysis of the mass spectra demonstrated that the analyte was transformed to unsaturated (elimination), alkoxy or hydroxyl end-groups (substitution) molecules when silver cationic agents were used; these results were also supported by 1H NMR study. When sodium salt was used as a cationic agent, well-defined bromine-terminated macromolecules were successfully determined through MALDI-TOF MS. Well-characterized esters of 2-bromo-2-methylpropanoate of poly(oxyalkylene) polymers could be used as ATRP macroinitiators for the synthesis of a variety of polymeric architectures of interest as drug delivery bioconjugates.

Investigation of poly(alpha-methyl styrene) tacticity synthesized by photo-polymerization

In this work, poly(alpha-methyl styrene) (PAS) was synthesized by free radical photo-polymerization. The tacticity and microstructure of PAS were studied by(13)C nuclear magnetic resonance spectroscopy (C-13 NMR). Assignments of all stereo sequences were carried out at pentad and hexad levels of quaternary aliphatic, quaternary aromatic, and methylene carbons using(13)C NMR in deuterated chloroform at 20 degrees C and 50 degrees C, respectively. It was found that by increasing the NMR acquisition temperature, higher resolution and higher splitting of the peaks were achieved for all mentioned carbons. Bernoullian and first-order Markov statistics were used for all carbons and the results were compared with experimental data by statistical method. It was shown that Bernoullian statics model fit slightly better than first-order Markov statics model for the assigned sequences. The results indicated that corresponding values of probability (P-m) was equal to 0.234, suggesting that the racemic addition was almost higher than the meso-one. The effect of the deuterated solvent on the peak resolution and the splitting of syndiotactic and isotactic sequences was investigated by replacing deuterated tetrahydrofuran with deuterated chloroform. It was observed that the peak resolution and the splitting in deuterated chloroform are much more than deuterated tetrahydrofuran.

Effect of Small Cage Guests on Dissociation Properties of Tetrahydrofuran Hydrates

It is well understood that tetrahydrofuran (THF) molecules are able to stabilize the large cages (5(12)6(4)) of structure II to form the THF hydrate with empty small cages even at atmospheric pressure. This leaves the small cages to store gas molecules at relatively lower pressures and higher temperatures. The dissociation enthalpy and temperature strongly depend on the size of gas molecules enclathrated in the small cages of structure II THF hydrate. A high-pressure microdifferential scanning calo- rimeter was applied to measure the dissociation enthalpies and temperatures of THF hydrates pressurized by helium and methane under a constant pressure ranging from 0.10 to 35.00 MPa and a wide THF concentration ranging from 0.25 to 8.11 mol %. The dissociation temperature of binary He + THF and methane + THF hydrates increases along with an increase in the THF concentration in the liquid phase at a fixed pressure (e.g., 30 MPa), reaching a maximum value of 280.8 and 312.8 K, respectively, at stoichiometric concentration (5.56 mol % THF), and then remains nearly constant for even higher THF concentrations (>5.56 mol %). The effect of gas occupancy in the small cages on the dissociation enthalpy of He + THF and methane + THF mixed hydrates was further examined by using molecular dynamics (MD) simulations. The dissociation enthalpy of the He-THF mixed hydrates is independent of pressure with an average of 5.68 kJ/mol H2O over the pressure ranging from 0.10 to 30.0 MPa, consistent with the MD results of the He-THF mixed hydrates with low single occupancy (<23%) of helium molecules in the small cages. Consequently, the heat of adsorption of helium molecules in the small cages of the He-THF mixed hydrates is rather too weak to be identified. On the other hand, the dissociation enthalpy of the methane-THF hydrates increases from 9.11 to 10.01 kJ/mol H2O along with an increase in methane pressure over the pressure ranging from 5.0 to 30.0 MPa, consistent with the MD results of the methane-THF mixed hydrates with full occupancy of methane molecules in the small cages. These findings provide important information for the design of a potential medium of gas storage and transportation. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Synthesis of 1,6-Dihydropyridine-3-carbonitrile Derivatives via Lewis Acid-Catalyzed Annulation of Propargylic Alcohols with (E)-3-Amino-3-phenylacrylonitriles

A novel Lewis acid-catalyzed, highly efficient, practical, and atom-economical protocol for the synthesis of functionalized 1,2-dihydropyridine-3-carbonitrile derivatives in the presence of Bi(OTI)(3) (10 mol %) in tetrahydrofuran (2.0 mL) at 80 degrees C for 8 h in air is described, starting from readily accessed propargylic alcohols and (E)-3-amino-3-phenylacrylonitriles. This cycloaddition protocol, which is scalable and proceeds under mild conditions, is amenable to the gram-scale construction of valuable 1,2-dihydropyridine-3-carbonitriles. Furthermore, the good functional group compatibility and broad scope of this strategy were demonstrated by a broad range of propargylic alcohols and (E)-3-amino-3-phenylacrylonitriles, with yields ranging from 34 to 96%.

Effect Of Magnesium Perchlorate Content on the Mechanical, Thermal Stability, and Dielectric Properties of Plasticized PMMA/PVC-g-PMMA Electrolytes

In this study, new types of gel polymer blend electrolytes (GPBEs) were prepared with the synthesized PVC-g-PMMA graft copolymer, PMMA, plasticizers (propylene carbonate (PC), dioctyl phthalate (DOP)), and different loadings of Mg(ClO4)(2) via the solution casting method using tetrahydrofuran as solvent. Fourier transform infrared (FTIR) spectra of the electrolytes showed mutual molecular interactions between Mg(ClO4)(2) and organic moieties. The scanning electron microscopy images of the GPBEs showed their wrinkled surface morphology due to their low elastic modulus and high flexibility. Energy-dispersive X-ray (EDX) spectroscopy and mapping technique revealed the regular distributions of all atomic elements such as Cl, Mg, O, and C in the doped GPBEs. With increasing the Mg salt concentration, Young’s modulus and tensile strength of the GPBEs strongly decreased. Interestingly, the elongation at break of the GPBEs was higher than that of neat (undoped) GPBE and achieved the highest value of 215% at the salt content of 20 wt.%. The AC conductivity and ionic conductivity, as well as dielectric permittivity of plasticized PMMA/PVC-g-PMMA/Mg(ClO4)(2) GPBE,s increased with frequency and Mg(ClO4)(2) doping content. Ionic conductivity of the doped GPBEs can be achieved from 5.51×10(-5) to 4.42×10(-4) (S.cm(-1)) using Mg(ClO4)(2) contents in the range from 10 to 40 wt.%. The doped GPBEs are thermally stable up to 100 degrees C with very low weight losses. The GPBE doped with 20 wt.% of Mg(ClO4)(2) can be used as a new type of electrolyte for developing Mg batteries.
