A comprehensive experimental study on the production of key platform chemicals from raw biomass

In recent years, the utilization of biomass resources in the production of industrial chemicals and fuels become more preferable when considering low cost, renewability and environmental concerns. In this study, 5-hydroxymethylfurfural and levulinic acid obtained from catalytic one-pot reaction of different feedstocks (microcrystalline cellulose, corn straw, sorghum and waste fluff) under the specified conditions (temperature, time, solvent ratio, catalyst loading) using different cosolvents (methanol, hexane, tetrahydrofuran (THF), acetone) in reaction medium. Over the Amberlyst-15 catalyst, significant increase in levulinic acid concentration was achieved using acetone as cosolvent thus 94.34 +/- 5.25 mg levulinic acid was obtained from 1 g sorghum at 180 degrees C for 30 min. The use of polar aprotic solvents such as THF and acetone promoted further hydrolysis of raw biomass materials in reaction medium.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 79-50-5, in my other articles.

Characterisation of Elastomers as Food Contact Materials-Part 1: Quantification of Extractable Compounds, Swelling of Elastomers in Food Simulants and Release of Elements

Elastomers are not a uniform class of materials but comprise a broad spectrum of chemically different polymers. Sealing gaskets, gloves, teats, conveyor belts and tubing are examples of elastomers being used as food contact materials (FCMs). Ten elastomer samples were evaluated with respect to the content of extractable compounds, migration of substances into ethanolic food simulants, swelling in food simulants and release of elements in different food simulants. The number of extractable substances <1000 Da was determined by comprehensive two-dimensional gas chromatography coupled with flame ionisation detection (GC x GC-FID) analysis of tetrahydrofuran (THF) extracts. The number of signals ranged from 61 (a thermoplastic elastomer (TPE)) to 690 (a natural rubber/styrene-butadiene-rubber blend (NR/SBR)). As for risk assessment, the decisive factor is which substances reach the food. The extent of substances that migrate into ethanolic food simulants was investigated. Elastomer FCMs can be the source of food contamination with heavy metals. Notably, contamination with lead was detected in some samples investigated in this study. It was shown that food simulants harbour the potential to morphologically alter or even disintegrate elastomeric materials. The results presented here highlight the importance to carefully choose the elastomer type for the intended use as FCMs as not every application may prove safe for consumers. Interested yet?

Electrochemical Signatures of Interface-Dominated Behavior in the Testing of Calcium Foil Anodes

Fundamental research and practical assembly of rechargeable calcium (Ca) batteries will benefit from an ability to use Ca foil anodes. Given that Ca electrochemistry is considered a surface-film-controlled process, understanding the interface’s role is paramount. This study examines electrochemical signatures of several Ca interfaces in a benchmark electrolyte, Ca(BH4)(2)/tetrahydrofuran (THF). Preparation methodologies of Ca foils are presented, along with Ca plating/stripping through either pre-existing, native calcium hydride (CaH2), or pre-formed calcium fluoride (CaF2) interfaces. In contrast to earlier work examining Ca foil in other electrolytes, Ca foils are accessible for reversible electrochemistry in Ca(BH4)(2)/THF. However, the first cyclic voltammetry (CV) cycle reflects persistent, history-dependent behavior from prior handling, which manifests as characteristic interface-derived features. This behavior diminishes as Ca is cycled, though formation of a native interface can return the CV to interface-dominated behavior. CaF2 modification enhances such interface-dominance; however, continued cycling suppresses such features, collectively indicating the dynamic nature of certain Ca interfaces. Cell configuration is also found to significantly influence electrochemistry. With appropriate preparation of Ca foils, the signature of interface-dominated behavior is still present during the first cycle in coin cells, but higher current density compared to three-electrode cells along with moderate cycle life are readily achievable.

Synthetic Route of 79-50-5, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 79-50-5 is helpful to your research.

Preparation of hydrophobic macroinimer-based novel hybrid sorbents for efficient removal of organic liquids from wastewater

Herein, the synthesis of hydrophobic macroinimer-based hybrid sorbents and their use in the removal of organic solvents from wastewater is explored. Polydimethylsiloxane (PDMS), 4,-4 ‘-azobis-4-cyanopentanoyl chloride (ACPC), and methacryloyl chloride were reacted via bulk condensation polymerization to synthesize the macroinimer. The organogel systems were then prepared with macroinimer using different acrylic monomers of methyl acrylate, ethyl acrylate, and butyl acrylate without any additional crosslinker and initiator. The structural properties of the obtained final products were characterized by FT-IR, H-1-NMR, and TGA. The effect of alkyl chain length and macroinimer moieties in the organogel networks, as well as the swelling capacities of the prepared gels, was evaluated for different organic solvents and oils. The maximum solvent absorbencies of macroinimer-based organogels were determined as 85.3%, 100.9%, 1422.1%, 1660.0%, 3809.3%, and 5032.2% for diesel oil, gasoline, acetone, benzene, tetrahydrofuran (THF), and dichloromethane (DCM), respectively. Furthermore, adsorption-desorption kinetics, selective absorption from oil/water mixtures, temperature effect on the absorption capacity, and reusability tests were investigated. Obtained results showed that the prepared organogels possessed high swelling, efficient absorption capacity, and good oil separation performance in the removal of organic solvents from wastewater. The temperature-dependent absorption study shows no significant change in absorption capacity. Thus, the prepared macroinimer-based organogels in the present study demonstrate potential as prospective sorbents for organic pollutant cleanup from wastewater.

Exergoenvironmental Analysis of Tetrahydrofuran/Ethanol Separation through Extractive and Pressure-Swing Distillation

Extractive distillation uses a high-boiling point solvent for changing the relative volatility of the azeotropic mixture, whereas pressure-swing distillation is based on the difference of operating pressures for such a purpose. In this paper, said separation technologies were applied to a tetrahydrofuran/ethanol mixture and compared with regard to their thermodynamic and environmental performances. The former was assessed by determining the total exergy destruction rate and rational efficiency of each configuration, while the latter was evaluated by estimating their respective indirect carbon emissions. The results showed that the pressure-swing process has not only the lowest exergy destruction rate (383.1 kW) but also the lowest CO2 emission rate (678.7 kg/h), which is mainly due to its lower thermal energy requirements. A sensitivity analysis was then carried out in order to determine how the carbon emissions respond to both the efficiency and the fuel type of the utility boiler.

Preparation of a Lanthanide-Titanium Oxo Cluster-Polymer Composite by Cu-I-Catalyzed Click Chemistry

Incorporating metal clusters within the skeleton of the organic polymers through a click reaction cannot only effectively prepare cluster-polymer composites, but also effectively avoid the cluster aggregation. Herein, an azide-containing lanthanide-titanium oxo cluster of Eu8Ti10-N-3 (Eu8Ti10-N-3=[Eu8Ti10(mu(3)-O)(14)(H2O)(4)(OAc)(2)(tbba)(30)(paza)(4)(THF)(2)].4 THF.8 H2O (1), Htbba=4-tert-butylbenzoic acid, Hpaza=4-azidobenzoate, HOAc=acetic acid, THF=tetrahydrofuran) through an in situ solvothermal reaction of 4-azidobenzoic acid and 4-tert-butylbenzoic acid. Reaction of 1 with PEG (PEG=methoxypoly(ethyleneglycol)alkyne, 2000 g mol(-1)) through Cu-I-catalyzed click chemistry generates a lanthanide-polymer composite of Eu8Ti10-N-3@PEG (2). Investigation with IR, H-1 NMR and ICP-OES of 2 indicates that the structural integrity of 1 is maintained in 2. Study of the luminescent properties of 1 and 2 reveals that the quantum yield of 1 itself basically remains unchanged in 2. Significantly, the formation of 2 cannot only effectively prevent the cluster 1 from aggregation, but also greatly enhance its solubility and adhesion to the substrate. Owing to the solubility and adhesion of luminescent materials being the key to their practical application, present work is thus of great significance for the development of metal cluster-polymer composite luminescent materials.

Studies of hydrogen isotope scrambling during the dehalogenation of aromatic chloro-compounds with deuterium gas over palladium catalysts

Catalytic dehalogenation of aromatic halides using isotopic hydrogen gas is an important strategy for labelling pharmaceuticals, biochemicals, environmental agents and so forth. To extend, improve and further understand this process, studies have been carried out on the scrambling of deuterium isotope with protium during the catalytic deuterodehalogenation of model aryl chlorides using deuterium gas and a palladium on carbon catalyst in tetrahydrofuran solution. The degree of scrambling was greatest with electron-rich chloroarene rings. The tetrahydrofuran solvent and the triethylamine base were not the source of the undesired protium; instead, it arose, substantially, from the water content of the catalyst, though other sources of protium may also be present on the catalyst. Replacement of the Pd/C catalyst with one preparedin situby reduction of palladium trifluoroacetate with deuterium gas and dispersed upon micronised polytetrafluoroethylene led to much reduced scrambling (typically 0-6% compared with up to 40% for palladium on carbon) and to high atom% abundance, regiospecific labelling. The improved catalytic system now enables efficient polydeuteration via the dehalogenation of polyhalogenated precursors, making the procedure viable for the preparation of MS internal standards and, potentially, for high specific activity tritium labelling.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 79-50-5, you can contact me at any time and look forward to more communication. Recommanded Product: 79-50-5.

Synthesis of Polycaprolactone Nanoparticles through Flow-Focusing Microfluidic-Assisted Nanoprecipitation

Polycaprolactone nanoparticles (PCL NPs) were produced by a liquid nonsolvent nanoprecipitation process in a flow-focusing microfluidic device and optimized in terms of particle size, polydispersity index (PDI), and zeta potential zeta. The effects of flow rate ratio (FRR), total flow rate (TFR), the organic solvents tetrahydrofuran and dimethylformamide (DMF), the surfactants polyvinyl alcohol and Tween 80, and polymer molecular weight on the size, PDI, and zeta of PCL NPs were investigated. A stability study was performed to compare the effect of the surfactants on the characteristics of PCL NPs over 7 d. The smallest particles are produced at the highest FRR, TFR, and polymer molecular weight and lowest polymer concentration in DMF. The presence of both surfactants results in smaller NPs.

A Rapid and reliable thin-layer chromatographic method for the simultaneous estimation of celecoxib and diacerein in their binary mixture using nanosilica gel plate

A novel, rapid, and sensitive stability-indicating high-performance thin-layer chromatography method was developed and validated for the simultaneous determination of celecoxib (CEL) and diacerein (DIA) in bulk and a capsule binary mixture. The complete separation was achieved by the proposed method on nanosilica gel F-254 plates using n-hexane-ethyl acetate-tetrahydrofuran-glacial acetic acid (7:3:1:0.8, V/V) as the mobile phase. The chromatographic bands were visualized using short-wave ultraviolet light, and the amount of CEL and DIA was determined by scanning densitometry at 254 nm using the peak area. The R-F values were 0.59 and 0.37 for CEL and DIA, respectively. From regression plots, it was found that good linearity was achieved in the concentration ranges of 20.00-320.00 ng/band and 5.00-80.00 ng/band with mean percentage recoveries 99.86 +/- 0.70 and 99.64 +/- 0.96 for CEL and DIA, respectively. The proposed method was validated according to the International Conference on Harmonisation guidelines. The statistical analysis of the results revealed high accuracy and precision, the suggested procedures could be used as a stability-indicating assay for the simultaneous determination of CEL and DIA in bulk drug and their capsule binary mixture in the presence of their degradation products.
