Low-Viscosity Ether-Functionalized Ionic Liquids as Solvents for the Enhancement of Lignocellulosic Biomass Dissolution

Due to the substantial usage of fossil fuels, the utilization of lignocellulosic biomass as renewable sources for fuels and chemical production has been widely explored. The dissolution of lignocellulosic biomass in proper solvents is vital prior to the extraction of its important constituents, and ionic liquids (ILs) have been found to be efficient solvents for biomass dissolution. However, the high viscosity of ILs limits the dissolution process. Therefore, with the aim to enhance the dissolution of lignocellulosic biomass, a series of new ether-functionalized ILs with low viscosity values were synthesized and characterized. Their properties, such as density, viscosity and thermal stability, were analyzed and discussed in comparison with a common commercial IL, namely 1-butyl-3-methylimidazolium chloride (BMIMCl). The presence of the ether group in the new ILs reduces the viscosity of the ILs to some appreciable extent in comparison to BMIMCl. 1-2(methoxyethyl)-3-methylimidazolium chloride (MOE-MImCl), which possesses the lowest viscosity value among the other ether-functionalized ILs, demonstrates an ability to be a powerful solvent in the application of biomass dissolution via the sonication method. In addition, an optimization study employing response surface methodology (RSM) was carried out in order to obtain the optimum conditions for maximum dissolution of biomass in the solvents. Results suggested that the maximum biomass dissolution can be achieved by using 3 weight% of initial biomass loading with 40% amplitude of sonication at 32.23 min of sonication period.

One-step sustainable synthesis of cationic high-swelling polymers obtained from starch-derived maltodextrins

The good water solubility displayed by most starch-derived maltodextrins has limited their use when specific mechanical properties are required, particularly when working in aqueous media. As a result, numerous attempts to cross-link such polysaccharides to obtain cross-linked polymers have been reported; in this context, non-toxic and biocompatible water-soluble diglycidyl ethers have performed well. Besides, amines are commonly used as curing agents in combination with diglycidyl ethers for the production of epoxy resins. For this reason, amine-mediated epoxy ring-opening reactions of 1,4-butanediol diglycidyl ether have been studied as approaches to obtain sustainable cross-linked polymers suitable for eco-friendly scaling-up, based upon commercial starch-derived maltodextrins, using water as a unique solvent.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2398-37-0 is helpful to your research. Application In Synthesis of 1-Bromo-3-methoxybenzene.

An Attempt to Formulate Non-Carbonate Electrolytes for Sodium-Ion Batteries

Non-aqueous carbonate solvents have been the main choice for the development of lithium-ion batteries, and similarly most research on sodium-ion batteries have been performed using carbonate-based solvents. However, the differences between sodium and lithium batteries – in term chemistry/electrochemistry properties as well as electrode materials used – open up opportunities to have a new look at solvents that have attracted little attention as electrolyte solvent. This work investigates properties of a wide range of different solvent classes in the context of sodium-ion battery electrolytes and compares them to the performance of propylene carbonate. The thirteen solvents studied here include one or several members of glymes, carbonates, lactones, esters, pyrrolidones, sulfones, and alkyl phosphates. Out of those, five outperforming solvents of gamma-butyrolactone (GBL), gamma-valerolactone (GVL), N-methyl-2-pyrrolidone (NMP), propylene carbonate (PC), and trimethyl phosphate (TMP) were further investigated using additives of ethylene sulfite (ES), vinylene carbonate (VC), fluoroethylene carbonate (FEC), prop-1-ene-1,3-sultone (PES), sulfolane (TMS), tris(trimethylsilyl) phosphite (TTSPI), and sodium bis(oxalato)borate (NaBOB). The solvents TMS and tetraethylene glycol dimethyl ether (TEGDME) were tested in 1 : 1 mixtures by volume with the co-solvents; NMP, dimethoxyethane (DME), and TMP. All electrolytes used NaPF6 as the salt. Primary evaluation relied on electrochemical cycling of full-cell sodium-ion batteries consisting of Prussian white cathodes and hard-carbon anodes. Galvanostatic cycling was performed using both two- and three-electrode cells, in addition, cyclic and linear sweep voltammetry was used to further evaluate the electrolyte formulations. Moreover, the resistance was measured on the anode and cathode, using Intermittent current interruption (ICI) technique.

High-temperature oxidation of propanol isomers in the mixtures with N2O at high Ar dilution conditions

This work provides, for the first time, new information regarding the kinetics interaction between N2O and propyl alcohol isomers. To this end, the formation and consumption of atomic oxygen were measured behind the reflected shock waves using Atomic Resonance Absorption Spectroscopy (ARAS) technique for 1-10 ppm n- i- propanol + 10 ppm N2O + Ar mixtures, at 2-3 bar and over a wide temperature range of 1700-3200 K. The Konnov and POLIMI detailed combustion mechanisms were assessed against experimental data and also employed to study the main reactions influencing the oxidation dynamics of fuel mixtures under the investigated conditions. The study highlighted a certain difficulty by the models tested in predicting the formation of atomic oxygen at T < 2000 K. The rate of production and the sensitivity analysis was performed with the attempt to identify the most important reactions involved in the process oxidation for future kinetic model refinements.

Influence of diethyl ether on engine performance and emissions characteristics of blends of butanol, pentanol or biodiesel (neem oil methyl ester) in a single cylinder diesel engine

Biodiesel has become a promising alternative biofuel that exhibits problems like high cost of feedstock, poor atomisation due to high viscosity, stability issues, poor flow properties and high NOx emissions as compared to conventional diesel. Alcohols have recently drawn much attention as a low cost biofuel that, exhibit problems like low cetane number and miscibility issues. Addition of fuel additives, for example, diethyl ether (DEE), may be effective to overcome the problems with biodiesel or alcohols. In this work, the influence of DEE on engine performance and emissions were investigated for diesel/biodiesel blends, diesel/butanol blends or diesel/pentanol blends. Fuel blends of biodiesel (B20), butanol (BU20), pentanol (PN20), biodiesel with DEE (B20D10), butanol with DEE (BU20D10) and pentanol with DEE (PN20D10) were prepared. Experiments were conducted on a single cylinder diesel engine for varying load conditions at constant speed. Engine performance and emission characteristics were determined and compared.

Synthesis, structure and property of two D-f heteronuclear Eu-TM (TM = Zn and Cd) complexes with open-chain ether Schiff base ligand

Two heteronuclear Zn-Eu and Cd-Eu complexes with open-chain ether Schiff base ligand (bis(5-bromine-3-methoxysalicylidene)-3-oxapentane-1,5-diamine (H2L) and isonicotinate (IN), with composition [ Zn2EuL2(OAc)(IN)](NO3)center dot(CH2Cl2) (1) and ([CdEuL(IN)(OAc)(NO3)(CH3OH)]center dot 3(CH2Cl2)}(n) (2), have been synthesized and characterized. The structure analysis reveals that the Zn-Eu complex is heterotrinuclear cluster and lanthanide ion acts as a joint bridging of two Zn-L coordination units, whereas the Cd-Eu complex is infinite 1D zigzag coordination polymer formed by Cd-Eu-L secondary units through bridging of isonicotinate. Fluorescence properties of complexes 1-2 in the solid state and DMF solution at room temperature were studied. It has been found that the emission spectra of complexes 1-2 do not exhibit corresponding Eu-III ion characteristic emission bands and the fluorescence properties of complexes 1-2 are different due to the introduction of different transition metal ions. Antioxidant properties of the ligand and complexes 1-2 were also studied, the results showed that the ligand and complexes 1-2 display high scavenging activity against hydroxyl (OH center dot) and superoxide (O-2(-)center dot) radicals, and the order of the activity is complex 2 > complex 1 > H2L. Therefore, the structures and properties of D-f heteronuclear complexes can be adjusted by selecting different transition metal ions such as Zn-II and Cd-II ions. (C) 2020 Elsevier B.V.

Vegetable fixed oils obtained from soursop agro-industrial waste: Extraction, characterization and preliminary evaluation of the functionality as pharmaceutical ingredients

This study was designed to evaluate the feasibility of using oils extracted from seeds of soursop industrial waste for use as pharmaceutical ingredients. For that, soursop seeds were subjected to different processes of extraction of fixed oil, by chemical and mechanical routes. After characterization of fixed oils, the feasibility of using them as pharmaceutical excipients was explored by preparing creams in which the oils were used as emollient and/or antioxidant excipient. The oil extracted from soursop seeds in a Soxhlet device and ethyl ether solvent (SFO) showed a yield of 30.72 +/- 0.09 % (w w(-1)) and, in a domestic extruder (MFO), 23.86 +/- 0.78 % (w w(-1)). These oils showed physicochemical attributes that indicative of good preservation. The major fatty acid was the oleic acid, with 42.94-43.73 % in relative area, followed by linoleic with 29.5%-30% in relative area. In the non-grease fraction, the SFO showed considerable levels of phenolics (194.5 +/- 31.1 mg kg(-1)) and tocopherols (608.2 +/- 36.7 mg kg(-1)), which gave it an antioxidant potential, confirmed by the 2,2-diphenyl-1-picrylhydrazyl test, with a concentration effective for 50% inhibition (IC50) of 2.8 mg mL(-1). Finally, the evaluation of the quality parameters of the creams, suggests that the use of fixed soursop oils to replace the synthetic ingredients usually incorporated (decyl oleate, liquid petrolatum and butylhydroxytoluene), originated formulations with adequate physical and chemical stability. These findings suggest that both oils obtained are possible candidates for use as emollients and antioxidant in pharmaceutical formulas. In addition, contributing to minimize the generation of waste from the fruit agribusiness and add economic value to a by-product generated in the production of fruit pulp. (C) 2021 Elsevier B.V.

Polybrominated diphenyl ethers exert genotoxic effects in pantropic spotted dolphin fibroblast cell lines

Cetaceans accumulate persistent and toxic substances such as polybrominated diphenyl ethers in their tissue. PBDEs are ubiquitous in marine environments, and their exposure to mammals is linked to numerous health effects such as endocrine disruption, neurotoxicity, carcinogenicity, and fetal toxicity. However, the toxicological effects and mechanism of toxicity in cetaceans remains poorly understood. The effects of BDE-47 (0.1-0.5 mu g mL(-1)), BDE-100 (0.1-0.5 mu g mL(-1)), and BDE-209 (0.25-1.0 mu g mL(-1)) exposure on cell viability, oxidative stress, mitochondrial structure, and apoptosis were evaluated using a recently established pantropical spotted dolphin (Stenella attenuata) skin fibroblast cell line (PSD-LWHT) as an in vitro model. However, the production of reactive oxygen species (ROS) increased following exposure to 1.0 mu g mL(-1) PBDE while superoxide anion, hydroxyl radicals, and inducible nitric oxide increased in a dose-dependent manner. At 0.5-1.0 mu g mL(-1), PBDEs significantly reduced the mitochondrial membrane potential. In addition, exposure to BDE-47 and -209 significantly affected mitochondrial structure as well as cell signaling and transduction compared to BDE-100. Although PBDE exposure did not affect cell viability, a significant increase in cell apoptosis markers (Bcl2 and caspase-9) was observed. This study demonstrated that BDE-47, -100, and -209 congeners might cause cytotoxic and genotoxic effects as they play a crucial role in the dysregulation of oxidative stress and alteration of mitochondrial and cell membrane structure and activity in the fibroblast cells. Hence, these results suggest that PBDEs might have adverse health effects on cetaceans inhabiting contaminated marine environments. (C) 2020 Elsevier Ltd. All rights reserved.

Contamination levels and temporal trends of legacy and current-use brominated flame retardants in a dated sediment core from Beppu Bay, southwestern Japan

Contamination levels and temporal trends of polybrominated diphenyl ethers (PBDEs) and some alternative brominated flame retardants (BFRs) were examined in a dated sediment core from the deepest part of the Beppu Bay, southwestern Japan. PBDEs were found in the upper layers of 0-15 cm depth at concentrations ranging from 5200 to 32,600 pg g(-1) with the peak estimated at 1995. Decabromodiphenyl ether (BDE-209) was the most abundant congener, accounting for 96% in average of total PBDEs. The vertical profile of BDE-209 observed in our sediment core generally agreed with the historical pattern of domestic demand of commercial deca-BDE mixtures in Japan, and perfectly matched with maximum stock of these products (i.e., 42,000 tons in 1995). Among alternative BFRs, only decabromodiphenyl ethane (DBDPE), a replacement of deca-BDE, was found at significant levels with concentrations of 69-850 pg g(-1) in sediment layers dated between 1991 and 2011. Ratios of DBDPE to BDE-209 gradually increased during this period, implying opposite trends of these two compounds and the role of DBDPE as a deca-BDE’s alternative. The occurrence of deca-BDE components in sediments may pose medium risk to benthic aquatic life, while the ecological risk of other PBDE homologs and DBDPE was negligible. (C) 2020 Elsevier Ltd.
