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.

Hydroconversion of Kraft lignin for biofuels production using bifunctional rhenium-molybdenum supported zeolitic imidazolate framework nanocatalyst

Non-noble bimetallic nanoparticles anchored on Zeolitic Imidazolate Frameworks, bifunctional ReMo@ZNB catalyst, has been demonstrated to promote Kraft lignin depolymerization. In this study, the catalytic activities under different heat treatment conditions are ranked as follows: ReMo@ZNB-700 (Air) > ReMo@ZNB-500 (Air) > ReMo@ZNB-700 (N-2). Particularly, bimetallic ReMo nanocatalyst with Re/Mo atomic ratio of 1/3 shows superior performance. Excellent yields of Ethyl acetate soluble products (92.18%) and Petroleum ether extracted biofuels (78%) are obtained at 300 degrees C and 24 h, and the calorific value is 32.33 MJ/kg. The ReMo@ZNB catalyst exhibits superior recyclability and regeneration after cycle experiment. Structural characterization results reveal that the incorporation of ReMo can engender the transformation of lattice morphology, the strength of hydrogenation and acid adsorption. The possible mechanism is based on the synergism of adsorption coupling and hydrogenation over ReMo@ZNB catalyst. The synergic action initiates potential perspectives for improving lignin hydroconversion.

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.

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.

Green solvent pretreatment for enhanced production of sugars and antioxidative lignin from poplar

A promising pretreatment mediated by biomass-derived deep eutectic solvent (DES) with choline chloride to lactic acid was implemented to overcome the recalcitrant structure of poplar sawdust for effective enzymatic hydrolysis and valorized lignin. Results showed the DES applied was strongly selective towards removal of lignin and xylan while preserving cellulose. Under the optimal pretreatment condition (DES ratio: 1:2, temperature: 130 degrees C, time:1.5 h), the glucose yield from enzymatic hydrolysis was 75.8%. Chemical and structure changes of recovered lignin were evaluated to gauge its valorization potential. It indicated that the recovered lignin possessed molecular weight (4000-6000 g/mol), low polydispersity (PDI < 2.0), low quantity of beta-aryl-ethers with no recondensation, and an abundance of phenolic OH groups. The excellent antioxidant capacity of lignin demonstrated its great value as a polyphenolic antioxidant. Overall, this work demonstrated an emerging biorefinery technology method for effective fractionation and valorization of lignocellulosic biomass. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 101-55-3, you can contact me at any time and look forward to more communication.

Determination and comparison of phospholipid profiles in eggs from seven different species using UHPLC-ESI-Triple TOF-MS

Egg yolk phospholipids from seven different species were purified (purity > 96%) using SPE columns, and subsequently the phospholipid profiles were identified and quantified by ultra-high-performance liquid chromatography-electrospray ionization-triple time-of flight mass spectrometry (UHPLC-ESI-Triple TOF-MS). Eight phospholipid classes and 87 molecular species were characterized. Principal component analysis showed that the molecular species and concentration of phospholipids in pigeon and hen egg yolks had a significant difference with other eggs. Hierarchical cluster analysis indicated that the phospholipid profiles of pigeon egg yolks were closest to hen egg yolks, followed by quail, duck, ostrich, emu and goose egg yolks. Different relative quantities of certain molecular species were different among egg yolk types; for instance, phosphatidylcholine (16:0/16:1) in goose egg yolks and phosphatidylethanolamine (16:0/18:3) in ostrich egg yolks. This study provides a basis for a better understanding of the phospholipid profiles of egg yolks, and better evaluation of the nutritional value of eggs.

Synthesis of three kinds of multi-armed cardanol-based acrylic resins based on different routes for UV/EB-cured coatings

In this work, we describe three kinds of multi-armed cardanol-based acrylic resins to fabricate UV/EB-cured coatings. Hydroxyethyl cardanol ether reacts with methyl etherified melamine formaldehyde resin to synthesize multi-arm cardanol-based oligomer (HF). HF was used to synthesize multi-arm cardanol-based epoxy acrylate (AEHF), cardanol acrylate (AHF), and cardanol-based polyurethane acrylate (ISHF) based on three different routes. The three synthetic routes were based on homogeneous catalytic system by peroxyacids through epoxidation and acrylate reactions, electrophilic addition reaction, and mercapto-olefin photo-click reaction. The structure and properties of AEHF, AHF, and ISHF were characterized by FR-IR, H-1-NMR and GPC. The three kinds of cardanol-based acrylic resins were used to prepare UV/EB-cured coatings, and the performance of the coatings was tested systematically. The hardness of AHF and ISHF coating has a high pencil hardness (3H), both adhesion of the three coatings can be improve to 0 grade after addition of phosphate resin. Compared with UV curing, EBcured was not require photo-initiators, the storage modulus and the pencil hardness of the coatings were higher. The three kinds of cardanol-based acrylic resins can be applied in UV/EB-cured coatings for metal protection and other fields.

Redox Instability of Copper(II) Complexes of a Triazine-Based PNP Pincer

The new Cu(I) complex [Cu(PNPNTPh-Ph)Cl] (1) containing the tridentate PNP pincer ligand N,N ‘-bis(diphenylphosphino)-2,6-diamino-4-phenyl-1,3,5-triazine was obtained from the reaction of [Cu(SMe2)Cl](n) with the ligand as ether solvate 1(.)0.5Et(2)O. 1 was independently obtained from a reaction mixture containing the ligand and the Cu(II) precursor CuCl(2)(.)2H(2)O in 50 % yield alongside with the Cu(II) coordination polymer [Cu(O2PPh2)(2)](n) (2). From the reaction of Cu(NO3)(2) . 3H(2)O with PNPNTPh-Ph in the presence of pyridine the complexes [Cu(O2PPh2)(2)(Py)(2)(H2O)] (3), [Cu(O2PPh2)(Py)(2)(NO3)](2) (4), and [Cu(Py)(4)(NO3)(2)]Py-. (5), were obtained, 2, 3, and 4 contain diphenyl-phosphinate ligands. The underlying redox reaction of the ligand and Cu(II) yielding the oxidised ligands observed in the by-products and the Cu(I) product complex was further studied using electrochemistry and UV-vis spectroelectrochemistry. Attempts to synthesise the Cu(II) complex [Cu(PNPNTPh-Ph)(NO3)(2)] (6) in a mechanochemical experiment gave evidence for this unprecedented species from ESI-MS(+) and EPR spectroscopy but also revealed its very high sensitivity to air and moisture. The catalytic activity of 1 was investigated in the azide-alkyne cycloaddition yielding various 1-benzyl-4-phenyl-1H-1,2,3-triazoles. The environmentally benign (green) and cheap EtOH/H2O solvent mixture turned out to be very suitable. Melting points, FT-IR, and NMR spectra of the triazole products were analysed.

Determination of 3-monochloropropanediol esters and glycidyl esters in fatty matrices by ultra-high performance liquid chromatography-tandem mass spectrometry

The development and validation of a method for the analysis of traces of 3-monochloropropanediol (3-MCPD) esters (19) and glycidyl esters (7) of fatty acids in vegetable oils, margarine, biscuits and croissants was performed. An extraction method based on the use of solvents (tert-butyl methyl ether (20% ethyl acetate, v/v)) was carried out and cleaning of the extract with a mixture of sorbents (Si-SAX, PSA and Z-sep+) was optimized for the elimination of fatty interferents. The analysis of the targeted compounds was carried out by ultra-high-performance liquid chromatography coupled to tandem mass spectrometry, using a triple quadrupole analyzer (UHPLC-MS/MS-QqQ). The validation of the method provided trueness values between 72 and 118% and precision lower than 20%. The limits of quantification ranged from 0.01 to 0.1 mg kg(-1), which were below the current legal limits. Twenty samples of vegetable oils as well of 4 samples of margarine, biscuits and croissants were analyzed. Six out of the 24 samples (25%) exceeded the limits set by European legislation, and a maximum contamination of 3-MCPD esters at 2.52 mg kg(-1) was obtained in a sample of corn oil (being 1-myristoyl-3-MCPD the compound detected at the highest concentration). A maximum concentration of glycidyl esters at 7.84 mg kg(-1) was determined in a soybean oil sample (glycidyl linoleate as the main compound). Only one sample of olive oil exceeded the maximum allowable limit for 3-MCPD esters with a value of 1.72 mg kg(-1), expressed as 3-MCPD. (C) 2021 Elsevier B.V. All rights reserved.

Inhibiting and promoting effects of NO on dimethyl ether and dimethoxymethane oxidation in a plug-flow reactor

The effects of NO addition (1000, 2000 ppm) on the low-temperature oxidation of dimethyl ether (DME) and dimethoxymethane (DMM), as particular cases of oxymethylene ethers (OMEn) with n = 0 and 1, have been investigated in a plug-flow reactor at near-atmospheric pressure in a temperature range of 400-1000 K. An in-situ electron ionization molecular-beam mass spectrometer (EI-MBMS) was used to measure the reactants, intermediates, and products, with particular attention on nitrogenous species that were scarcely detected previously. Explorative modeling with published mechanisms was performed, indicating the necessity of further model development. Potential kinetic fuel/NO interactions are discussed based on the experimental observations. The results reveal an overall inhibiting effect of NO addition on DME reactivity in the low-temperature regime, but a pronounced promoting effect at higher temperatures. For DMM, a similar temperature-dependent effect of NO was observed, but only for high NO concentration (2000 ppm). NO addition significantly suppresses the formation of hydrocarbon intermediates for both DME and DMM, but remarkably promotes the formation of methyl formate and methanol for DME. Several nitrogenous species were detected upon NO addition. The interactions of NO + HO2 and NO + OH, together with the regeneration routes of NO, are thought to be influential for both DME and DMM oxidation, while the significance of the NO + RO2 (R, fuel radical) reaction depends on the reactivity of the respective RO2 radical of DME and DMM. These results contribute to the understanding of OMEn/NO interactions and serve as a basis for further model development by providing new and detailed speciation data for DME/NO and DMM/NO oxidation.
