Chen, Shuang published the artcileSynthesis of T-Type low-viscosity hydrocarbon bio-lubricant from fatty acid methyl esters and coconut oil, Recommanded Product: Methyl decanoate, the main research area is fatty acid methyl ester coconut oil viscosity hydrocarbon biolubricant.

Biomass-derived long-chain alkanes with highly sym. branches, which show comparable properties to traditional petrochem.-based poly-α-olefin (PAO), have great potential economic value for industrial application. In this work, we developed a new strategy to prepare T-type low-viscosity bio-lubricant base oil using inexpensive lipid-derived fatty acid Me esters (FAMEs) as raw materials with a total carbon yield of around 67.3%. The fatty acid Me ester compounds (R1-COOCH3) were converted to fatty alcs. using methanol as the solvent and hydrogen donor over the Cu/SiO2 catalyst. Subsequently, fatty alc. was further brominated to the Bromo-Grignard reagents (R1-CH2-MgBr). In the next step, a T-type synthetic bio-lubricant base oil (R1-C(R2)-R1) was formed by the hydrodeoxygenation of sym. tertiary alc. precursors over Pd/C, where sym. tertiary alc. precursors were obtained via the nucleophilic addition of Bromo-Grignard reagents with fatty acid Me ester (R2-COOCH3). The specific properties of the branched representative bio-lubricant C32 (12’10’10’) are comparable to those of the com. lubricant PAO 3.6. This strategy offered a new promising route for synthesizing high-quality bio-lubricant base oil.

Li, Guangchen published the artcileHighly Chemoselective, Transition-Metal-Free Transamidation of Unactivated Amides and Direct Amidation of Alkyl Esters by N-C/O-C Cleavage, Category: esters-buliding-blocks, the main research area is chemoselective transamidation unactivated amide amidation alkyl ester.

The amide bond is one of the most fundamental functional groups in chem. and biol. and plays a central role in numerous processes harnessed to streamline the synthesis of key pharmaceutical and industrial mols. Although the synthesis of amides is one of the most frequently performed reactions by academic and industrial scientists, the direct transamidation of tertiary amides is challenging due to unfavorable kinetic and thermodn. contributions of the process. Herein, we report the first general, mild, and highly chemoselective method for transamidation of unactivated tertiary amides by a direct acyl N-C bond cleavage with non-nucleophilic amines. This operationally simple method is performed in the absence of transition metals and operates under unusually mild reaction conditions. In this context, we further describe the direct amidation of abundant alkyl esters to afford amide bonds with exquisite selectivity by acyl C-O bond cleavage. The utility of this process is showcased by a broad scope of the method, including various sensitive functional groups, late-stage modification, and the synthesis of drug mols. (>80 examples). Remarkable selectivity toward different functional groups and within different amide and ester electrophiles that is not feasible using existing methods was observed Extensive exptl. and computational studies were conducted to provide insight into the mechanism and the origins of high selectivity. We further present a series of guidelines to predict the reactivity of amides and esters in the synthesis of valuable amide bonds by this user-friendly process. In light of the importance of the amide bond in organic synthesis and major practical advantages of this method, the study opens up new opportunities in the synthesis of pivotal amide bonds in a broad range of chem. contexts.

Magnotti, Gina M. published the artcileAssessing fuel property effects on cavitation and erosion propensity using a computational fuel screening tool, Name: Methyl decanoate, the main research area is computational fuel screening tool erosion propensity.

To advance compression ignition combustion strategies, researchers have evaluated fuel property effects and their impact on achieving higher efficiencies and lower emissions levels relative to current capabilities. Within the Department of Energy′s Co-Optima initiative, there has been a recent focus on understanding the influence of fuel properties on fuel injection performance. To help identify candidate fuels that can meet desired injector performance metrics, a computational fuel screening tool is under development that can link fuel properties with the tendency of a given fuel to cavitate and lead to cavitationinduced erosion. In the initial development of this tool, five liquid fuel properties were selected to represent candidate fuels, namely, d., viscosity, vapor pressure, surface tension, and heat of vaporization. A design of experiments methodol. was used to generate a set of pseudofuel cases, which can represent the main effects and interactions among the fuel properties and be related to cavitation erosion predictions. Large eddy simulations were performed using a mixture modeling approach to predict the cavitation and erosion propensity of these pseudofuels in terms of the mean fuel vapor mole fraction and stored impact energy from repeated cloud collapse events. The low-order regression models generated from this study revealed the importance of liquid fuel d. on cavitation formation, whereas liquid viscosity was found to have a strong neg. correlation with erosion severity. The surrogate models were then used in the fuel screening tool to rank the cavitation and erosion tendency of four candidate single-component fuels: Me decanoate, iso-octane, ethanol, and n-dodecane. While the fuel screening tool was not able to quant. predict the cavitation and erosion response metrics, the tool was able to accurately rank the relative cavitation and erosion propensity of the four fuels. Overall, ethanol and iso-octane were observed to produce the highest levels of cavitation and erosion, resp.

Matrisciano, Andrea published the artcileAn a priori thermodynamic data analysis based chemical lumping method for the reduction of large and multi-component chemical kinetic mechanisms, Category: esters-buliding-blocks, the main research area is decane methylnaphthalene combustion mechanism kinetics.

A chem. species lumping approach for reduction of large hydrocarbons and oxygenated fuels is presented. The methodol. is based on an a priori anal. of the Gibbs free energy of the isomer species which is then used as main criteria for the evaluation of lumped group. Isomers with similar Gibbs free energy are lumped assuming they present equal concentrations when applied to standard reactor conditions. Unlike several lumping approaches found in literature, no calculation results from the primary mechanism have been employed prior to the application of our chem. lumping strategy. An 807 species and 7807 individual reactions detailed mechanism comprising n-decane, α-methylnaphthalene and Me decanoate has been used. The thermodn. data have been analyzed and 74 isomer groups have been identified within the oxidation of n-decane and Me decanoate. The mechanism reduction has led to a mechanism size of 463 species and 7600 reactions. Thereafter the lumped mechanism has been checked under several reactor conditions and over a broad range of temperature, pressure, and equivalence ratio in order to quantify the accuracy of the proposed approach. In all cases, very good agreement between the predictions obtained using the lumped and the detailed mechanism has been observed with an overall absolute error below 12%. Effects of the lumping procedure on sensitivities and on isomer concentrations were considered to further demonstrate the validity of the proposed approach.

Fang, Jun published the artcileSooting tendency analysis of oxygenate-diesel blended fuels by the affecting indicators of carbon number, oxygen content and H/C ratio, Product Details of C11H22O2, the main research area is oxygenate diesel blended fuel sooting tendency analysis.

This study exptl. assessed the sooting tendencies of the diesel fuel blended with typical oxygenated additives. Based on the known influential factors of oxygenated functional group, oxygen content, carbon number, and saturation degree, the functional numbers of carbon and oxygen atoms of the mols. were determined by considering the actual bonding ratio of carbon and oxygen producing CO and CO2 during the combustion of blends. The affecting indicators along with a calculation algorithm were proposed, taking into account the actual effect of each factor on sooting tendency. So-called indicators were termed the affecting oxygen content, carbon number and H/C ratio. Normalized Oxygen Extended Sooting Index (OESI) values incorporating the smoke point values were established to decrease with increasing blending percentage of the oxygenated additives in blends, following an exponential fitting relationship. The resulting exponents quantified the soot inhibition ability of the oxygenated additives, which decreased in the order: ethanol (EA) > n-butanol (NBA) > Me tertiary-Bu ether (MTBE) > dimethoxy methane (DMM) > Me decanoate (MD) > Me butanoate (MB) > di-Bu maleate (DBM) > di-Me carbonate (DMC). A combination of the absolute affecting indicator values generated by the suggested algorithm and their relative weights obtained by Relative Weight Anal. (RWA) could interpret the sooting tendency of most of the blended fuels very well. It was found that the sooting tendency was mainly determined by the absolute values of the affecting indicators, and the priority should follow the results by RWA, that decreased in the order of affecting carbon number > affecting oxygen content > affecting H/C ratio. This study could benefit the evaluation of the sooting tendency of the oxygenate-diesel blended fuels.

Gonzalez-Rodriguez, Jorge published the artcilePolymeric ionic liquids derived from L-valine for the preparation of highly selective silica-supported stationary phases in gas chromatography, SDS of cas: 110-42-9, the main research area is valine polymeric ionic liquid silica gas chromatog stationary phase; cross-linked stationary phases; gas chromatography; ionic liquids; solvation parameter model.

A series of silica-supported polymeric ionic liquid (PIL)-based stationary phases derived from a vinylic L-valine ionic liquid monomer and divinylbenzene (DVB) as the crosslinking agent have been prepared and studied as gas chromatog. stationary phases. These coated gas chromatog. columns exhibited good thermal stabilities (230-300 °C) and high efficiencies (1700-2700 plates/m), and were characterized using a linear solvation parameter model in order to understand the effects of the amount of DVB on the features of the resulting composite systems. Their retention behavior and separation efficiencies were demonstrated using the Grob test. By tuning the crosslinking degree for the IL-derived stationary phase, the separation selectivity and resolution of different compounds were improved. The different retention behaviors observed for many analytes indicate that these stationary phases may be applicable as new types of GC stationary phases.

Ma, Pan published the artcileMARS 2: A computational tool to resolve and extract features from large-scale GC-MS datasets, Related Products of esters-buliding-blocks, the main research area is MARS computational tool resolve extract GC MS dataset.

MARS (MS-Assisted Resolution of Signal) is a computational tool for feature extraction using multivariate curve resolution approaches. However, it is time-consuming for large-scale GC-MS datasets and sensitive to the component number estimation Here we introduce MARS 2 with substantial improvements to overcome these limitations. Reverse matching (RM) and principal component optimization-iterative transformation target factor anal. (PCO-ITTFA) are developed to reduce the time for locating peak regions and determine the correct component number for resolving optimal features. The greatest strength of MARS 2 is “”resolve once, extract anywhere””. It means that mass spectra of each component were needed to resolve from only one profile. Then, chromatog. features can be extracted automatically from hundreds of other profiles with the assistance from the resolved mass spectra. To evaluate its performance, plasma datasets and fatty acid standard mixtures were processed by MARS 2, AMDIS, ADAP-GC 3.0, eRah and MS-DIAL. Amino acid standard mixtures were analyzed by MARS 2 for calibration. Results show that MARS 2 can achieve better performance in both qual. and quant. anal.

Yang, Peng published the artcileMetagenomic and metabolomic profiling reveals the correlation between the microbiota and flavor compounds and nutrients in fermented sausages, Computed Properties of 110-42-9, the main research area is metagenomics metabolomics microbiota flavor compound nutrient fermented sausage; Fermented sausages; Flavor compounds; Metabolic pathways; Microbiota; Nutrients.

Understanding the interrelationships between the differentially abundant microorganisms and metabolites of traditional Fuet fermented sausages (FSs) and inoculated fermented sausages (IFSs) can help us identify key species that are missing from com. starter cultures to reproduce the flavor compounds and nutrients of traditional Fuet FSs. IFSs, inoculated with P. pentosaceus, P. acidilactici, S. xylosus, S. carnosus (SBM-52) or P. pentosaceus, and S. xylosus (THM-17), were deficient in reproducing the volatilome profile (in particular esters, Me aldehydes, and Me ketones) of traditional Fuet FSs because of the lack of diverse Staphylococci (S. carnosus, S. xylosus, S. equorum, and S. saprophyticus). Moreover, the combination of Pediococcus and Staphylococcus were pos. associated with amino acid, fatty acid, L-anserine, and L-carnosine levels. Pyridoxal and indolelactic acid levels were significantly increased in IFSs with the addition of P. acidilactici and S. carnosus, which were pos. associated with vitamin B6 and tryptophan metabolic pathways.

Zhang, Hailong published the artcileStructure-reactivity study of model and Biodiesel soot in model DPF regeneration conditions, Application In Synthesis of 110-42-9, the main research area is biodiesel soot catalytic oxidation diesel engine particulate filter.

The aim of the present work is to investigate and compare the non-catalytic and catalytic reactivities of real and model soot samples through temperature-programmed oxidation (TPO). Such reactivity was furthermore correlated with soot structural properties, determined by laser granulometry, XRD, Raman and HRTEM. Biodiesel soot samples were obtained through the combustion of different fuels in a real engine, whereas model soot samples were produced in a laminar burner. TPO evidenced that the soot generated with 100% Biodiesel (Me ester) was more reactive than real soot generated with 7% Biodiesel (7% Me ester). The model soot from the diesel surrogate (Aref) containing 7% oxygenate additive (C11H22O2) exhibited higher reactivity than the model soot containing 30% additive, whereas a carbon black (Degussa Printex U) showed the poorest reactivity of this series. The presence of NO2 promoted the non-catalytic oxidation of real soot. In the presence of the MnOx-CeO2 catalyst, soot reactivity depended both on reactant gas composition and on soot-catalyst contact.
