Synthesis and characterization of polypropylene glycol-based novel organogels as effective materials for the recovery of organic solvents

In this study, novel hydrophobic organogels were successfully prepared via the aza-Michael addition reaction method using diamino terminated polypropylene glycol and diphenylmethane bismaleimide as monomers, in the presence of a tri-amino functional polypropylene glycol as a crosslinking agent. The chemical structures, surface morphology, and thermal stability of the synthesized organogels were analyzed using Fourier transform infrared spectroscopy and solid-state CPMAS(13)C-NMR, scanning electron microscope, and thermal gravimetric analysis technique, respectively. The effects of various parameters, such as the monomer ratio, amount of crosslinker, and as well as swelling properties of organogels by solvent absorption tests were studied. According to obtained results, the solvent uptake capacity increased with decreasing crosslinker ratio up to 30 wt%. The maximum solvent absorbency of the synthesized organogels were determined as 730%, 504%, 271%, 224%, 95%, and 17% for dichloromethane, tetrahydrofuran, benzene, acetone, gasoline and diesel oil, under optimum conditions, respectively. In addition, reusability of the organogels was evaluated for 10 cycles, depicting no significant loss in absorbance capacity. The fabricated organogels showed high solvent absorption efficiency with prospects as suitable material for the recovery of a wide range of organic solvents.

Circularly Polarized Luminescence from Chiral Supramolecular Polymer and Seeding Effect

H-bonding driven J-type aggregation and cooperative supramolecular polymerization of a sulfur-substituted chiral naphthalene-diimide (NDI)-derivative (S,S)-NDI-2 in decane leads to remarkable enhancement of fluorescence quantum yield (43.3 % from 0.5 % in the monomeric state) and intense CPL signal in the aggregated state with a high luminescence dissymmetry factor (g(lum)) of 4.6×10(-2). A mixture of NDI-2 with a structurally similar NDI-derivative NDI-1 (mixture of racemic (S,S)- and (R,R)- isomers and the achiral derivative) in 1:9 (NDI-2/NDI-1) ratio, when heated and slowly cooled to room temperature, showed no enhanced CD band, indicating lack of any preferential helicity. However, when a monomeric solution of the NDI-1 in tetrahydrofuran (THF) was injected to preformed seed of NDI-2 in decane, a prominent CD signal appeared, indicating chiral amplification resulting in induced CPL with highg(lum)value of 2.0×10(-2)from mostly (>98.5 %) diastereomeric mixture.

Solid-liquid equilibrium solubility, thermodynamic properties and solvent effect of 3,4-dinitro-1H-pyrazole in different pure solvents

Knowledge of solubility and thermodynamic properties of 3,4-dinitro-1H-pyrazole (DNP) within different solvents are essential in the processes of crystallization and further theoretical studies. In this study, the solubility of DNP in 12 pure solvents (i.e., water, n-propanol, isobutyl alcohol, n-pentanol, isoamyl alcohol, xylene, ethyl acetate, epichlorohydrin, chloroform, acetonitrile, tetrahydrofuran and 2-butanone) has been determined by using gravimetric method within the temperature range of (283.15-323.15) K under atmospheric pressure. Good dissolution ability was found for DNP in the organic solvents we studied. The sequence of the mole fraction solubility is tetrahydrofuran >2-butanone > n-propanol > n-pentanol > isobutyl alcohol > isoamyl alcohol > acetonitrile > ethyl acetate > epichlorohydrin > xylene > water > chloroform. Solubility of DNP increased with the increasing temperature in each pure solvent. In addition, solubility data was correlated by four models including the modified Apelblat equation, NRTL model, Wilson model and Two-Suffix Margules model. The maximum rootmean-square deviation (10(4)RMSD) was 715.47. Basically speaking, values of R-2 and 10(4)RMSD between experimental and calculated solubility showed that NRTL model provided most satisfactory fitting results in this work. Moreover, Hansen solubility parameters (delta(d), delta(p), delta(h), delta(t), delta(v) and Delta delta(t)) were used to describe the dissolution characteristics of solid in different solvents. Then, the Kamlet-Taft parameters (alpha, beta and pi*) were explained to investigate the solvent effect on DNP solubility. Furthermore, other parameters, including mixing enthalpy (Delta H-mix) mixing entropy (Delta S-mix) and mixing Gibbs energy (Delta(mix)G) were calculated according to the Wilson model, and their results have been discussed on the basis of experimental data. It has been found that all mixing Gibbs energy are less than zero, hence, the dissolution of DNP is a spontaneous process. (C) 2020 Elsevier B.V. All rights reserved.

Facile synthesis and characterization of macromolecular Eu(III) complexes with beta-diketone ligands and poly(4-vinyl pyridine-co-methyl methacrylate)

Poly(4-vinyl pyridine-co-methyl methacrylate), PVM, was synthesized by radical copolymerization of 4-vinyl pyridine with methyl methacrylate. Afterward, the macromolecular Eu(III) complexes of general formula [Eu(beta-diketonate)(3)(PVM)(H2O)], where beta-diketonate = benzoylacetonate (BA),1; dibenzoylmethanate (DBM),2; thenoyltrifluoroacetonate (TTA),3, were prepared and fully characterized by means of element analysis, thermal analysis, SEM,H-1 NMR,C-13 NMR, FT-IR, and UV-vis spectra. The macromolecular complexes can dissolve in many ordinary organic solvents (e.g. dimethylformamide, dimethylsulfoxide, and tetrahydrofuran), as well as emit strong red luminescence under ultraviolet light excitation. The room-temperature(5)D(0)lifetime and fluorescence quantum yield of3are 391 mu s and 37%, respectively, which are far more than those of1(194 mu s, 16%),2(160 mu s, 18%), and Eu(TTA)(3)(H2O)(2)(224 mu s, 22%). The CIE coordinates of1-3are calculated as (0.49, 0.33), (0.62, 0.33) and (0.65, 0.34), respectively, demonstrating the promising utilization future of these complexes, especially the latter two, as luminescent functional materials used in large-area optical display.

Selection of calibration compounds for selectivity evaluation of siloxane-bonded silica columns for reversed-phase liquid chromatography by the solvation parameter model

For the faster evaluation of selectivity in reversed-phase liquid chromatography of siloxane-bonded silica columns using the solvation parameter model a minimal set of calibration compounds is described suit-able for mobile phase composition from 20-70% (v/v) methanol-, acetonitrile-, or tetrahydrofuran-water. The Kennard-Stone uniform mapping algorithm is used to select the calibration compounds from a larger database of compounds with known retention properties used earlier for column selectivity evaluation. Thirty-five compounds are shown to be necessary to minimize the standard deviation of the system constants and to minimize the difference between the system constants determined by conventional calibration and the values obtained for the reduced calibration compounds. The models for SunFire C-18 with methanol-, acetonitrileand tetrahydrofuran-water mobile phase compositions and XBridge Shield RP18, XBridge C-8 , XBridge Phenyl and Discovery HS F5 with methanoland acetonitrile-water mobile phase compositions had an average coefficient of determination of 0.996 (standard deviation = 0.003, n = 11) and average standard error of the estimate 0.025 (standard deviation = 0.005, n = 11) for the reduced calibration compounds. Some octadecylsiloxane-bonded silica stationary phases with a high bonding density and methanol-water mobile phase compositions containing <= 30% (v/v) methanol exhibit extreme retention factors (log k > 2.5) for the low-polarity, two-ring aromatic compounds in the thirty-five compound calibration set. Alternative calibration compounds with more favorable retention properties are suggested as replacements in these cases. The predictive capability of the calibration models is validated using external test sets characterized by the average error, average absolute error and root mean square error of prediction . For the thirty-five calibration compounds sets the average absolute error 0.026 (standard deviation = 0.009, n = 11) and root mean square error of prediction 0.032 (standard deviation = 0.010, n = 11) confirm the suitability of the calibration models for column selectivity evaluation. System maps for XBridge Shield RP18 for 20-70% (v/v) methanol-water and Synergi Hydro-RP and 50% (v/v) methanol water at temperatures from 25-65 degrees C together with a correlation diagram for XBridge Shield RP18 and SunFire C-18 are presented as representative applications of the reduced calibration compounds for column selectivity evaluation.

Self-aggregation of zinc bacteriochlorophyll-d analog bearing B-ring reduced chlorin and 17-acrylate residue

As a model of bacteriochlorophyll(BChl)-d specifically found in major light-harvesting antennae (chlorosomes) of photosynthetic green bacteria, zinc methyl 7,8-dihydro-17,18,17(1),17(2)-tetradehydro-bacteriopheophorbide-d was prepared from naturally occurring BChl-a through the double dehydration of the cis-17,18-diol. The synthetic B-ring reduced Zn-BChl-d analog bearing the 17-acrylate residue in tetrahydrofuran exhibited a more bathochromically shifted Soret band in the monomeric state than its counterpart with the 17-propionate residue, while the former’s Qy band slightly moved to a longer wavelength and was somewhat broadened in comparison with the latter’s. Compared with the monomeric bands, the acrylated pigment self-aggregated in 1% tetrahydrofuran and hexane to give more red-shifted and broadened Soret and Qy bands at blue-to-green and far-red regions, respectively, which were similar to the J-aggregates of BChl-d in chlorosomes. By contrast, the propionated pigment remained monomeric under the same conditions. These spectral differences were owing to the 17-substitution effect including the pi-conjugating and electron-withdrawing 17-acrylate residue. (C) 2020 Elsevier Ltd. All rights reserved.

Functionalization Mechanism of Reduced Graphene Oxide Flakes with BF3 center dot THF and Its Influence on Interaction with Li+ Ions in Lithium-Ion Batteries

Doping of graphene and a controlled induction of disturbances in the graphene lattice allows the production of numerous active sites for lithium ions on the surface and edges of graphene nanolayers and improvement of the functionality of the material in lithium-ion batteries (LIBs). This work presents the process of introducing boron and fluorine atoms into the structure of the reduced graphene during hydrothermal reaction with boron fluoride tetrahydrofuran (BF3 center dot THF). The described process is a simple, one-step synthesis with little to no side products. The synthesized materials showed an irregular, porous structure, with an average pore size of 3.44-3.61 nm (total pore volume (BJH)) and a multi-layer structure and a developed specific surface area at the level of 586-660 m(2)/g (analysis of specific surface Area (BET)). On the external surfaces, the occurrence of irregular particles with a size of 0.5 to 10 mu m was observed, most probably the effect of doping the graphene structure and the formation of sp(3) hybridization defects. The obtained materials show the ability to store electric charge due to the development of the specific surface area. Based on cyclic voltammetry, the tested material showed a capacity of 450-550 mAh/g (charged up to 2.5 V).

Probing effects of thermal and chemical coupling method on decomposition of methane hydrate by molecular dynamics simulation

Methane hydrate, being a potential alternative energy source has attracted the attention of many researchers. Here, we investigated the decomposition of methane hydrate with and without alcohols at different temperatures. The results showed that the hydroxyl group of alcohol molecules close to methane hydrate tends to reorient toward methane hydrate. The formation of hydrogen bonds between alcohol and water in methane hydrate cages destabilises the (methane hydrate) structure, thus leading to its decomposition. We also studied the effects of temperature on alcohols used during methane hydrate decomposition by comparing the variations in total potential energy with temperature. We observed that 300 K is the turning point, when the temperature is lower than 300 K, the accelerating effect of alcohol on methane hydrate decomposition is more pronounced. Additionally, the effect of temperature was found to vary with alcohols. For methanol, temperature mainly affects the rate of diffusion; a high rate of diffusion accelerates the decomposition of methane hydrate. For glycerol, temperature mainly affects the interaction energy between glycerol and water, which can accelerate the decomposition of methane hydrate. Our work provides a theoretical basis for future researches into exploitation of methane hydrate by combining thermal stimulation and alcohol. (C) 2020 Published by Elsevier B.V.
