Hedayati Marzbali, Mojtaba published the artcileHydrothermal carbonisation of raw and dewatered paunch waste: Experimental observations, process modelling and techno-economic analysis, SDS of cas: 110-42-9, the main research area is cellulose glucose xylose dewatered paunch waste hydrothermal carbonization.

In this study, dewatered and raw paunch waste, with 15 and 3 wt% total solids resp., generated at abattoirs was hydrothermally carbonized under subcritical water conditions. Higher solids content was found to produce higher hydrochar yield (i.e. 53% for 15 wt% compared to 33.5% for 3 wt%) at similar operating conditions of 10 bar and 240°C for 5 min. The morphol. differences were noted via SEM (SEM) in the hydrochar samples, and the surface area for processing raw paunch waste was found to be 68.1 m2 g-1 compared to 10.8 m2 g-1 in the case of dewatered paunch waste. The light bio-oil was mostly composed of phenolic compounds while the heavy bio-oil mainly contained long-chain fatty acids and their esters. Following the exptl. work, a full-scale ASPEN Plus process model was developed for a typical abattoir generating 27-tonne dry paunch waste per day. Pre-heater and hydrochar dryer contributed to 73% and 57% of the total energy for processing raw and dewatered paunch waste, resp., because of the high moisture content of the feedstock and hydrochar. After the equipment sizing and estimation of capital and operating costs, the discounted cash flow anal. was performed using the Nth-Plant financing assumptions. It was concluded that treating dewatered paunch waste is preferable as it: needed a smaller reactor i.e. lower overall initial investment, was less sensitive to bio-oil price, and improved the net present value over a period of 30 years to .8 MM. Besides the liquid hourly speed velocity, its com. viability is highly sensitive to the internal rate of return and existence of hydrochar dryer.

Le, Linh published the artcileUnexpected CNN-to-CC Ligand Rearrangement in Pincer-Ruthenium Precatalysts Leads to a Base-Free Catalyst for Ester Hydrogenation, Formula: C11H22O2, the main research area is bidentate pyridylbenzimidazolylidene ruthenacycle preparation catalyst ester hydrogenation; crystal structure bidentate pyridylbenzimidazolylidene ruthenacycle; mol structure bidentate pyridylbenzimidazolylidene ruthenacycle.

The authors report the conversion of CNN-pincer-Ru complexes Ru(CNN)HCl(CO) to a CC-chelated form Ru(CC)(PR3)2H(CO) on reaction with Na tert-butoxide and monodentate phosphines. When the phosphine is PPh3, cis-phosphine complexes form at room temperature, which convert to the trans isomer at elevated temperatures When the phosphine is tricyclohexylphosphine, only the trans-phosphine isomer is observed The CC-chelated complexes are active catalysts for the hydrogenation of esters, without the need for added base. The ligand structure-activity relation in CC-chelated complexes mirrors that in the precursor CNN-Ru complexes, potentially indicating a common catalytic mechanism. D. functional theory calculations establish a plausible mechanism for the CNN-to-CC rearrangement and demonstrate that this rearrangement is potentially reversible under the conditions of ester hydrogenation catalysis.

Lubinska-Szczygel, Martyna published the artcileInfluence of steam cooking on pro-health properties of Small and Large variety of Momordica charantia, Quality Control of 110-42-9, the main research area is Momordica fruit steam cooking methanol extract octanal antioxidant.

Steam cooking is one of the most common preparations of Momordica charantia dishes. This method improved the tastiness of the fruits but at the same time, some changes occurred in the volatile and non-volatile parts of their food matrixes. In this study, for the first time these properties were correlated with the found substances affecting the bioactivity of this fruit. Two varieties of Momordica charantia were analyzed and compared. It was possible to differentiate both types of fruits using two-dimensional gas chromatog. and time-of-flight mass spectrometry (GC×GC-TOF-MS) as well as to assess botanical and geog. origin. In the case of volatiles, 212 chem. compounds were tentatively identified, which can be classified into seven chem. classes, such as aldehydes, alcs., esters, ketones, terpenes, hydrocarbons. Furthermore, 16 of them were quantified and calculated in terms of OAV and ROC values. Bioactive substances (polyphenols, flavonoids, tannins and flavanols) and the values of antioxidant capacities by four radical scavenging assays (DPPH, CUPRAC FRAP, ABTS) were determined and compared in water and methanol extracts of Chinese and Indian varieties. It was proven that steam cooked Chinese variety has greater value due to its flavor than Indian variety and consists more volatile, non-volatile and bioactive constituents with high antioxidant effect. The binding properties of polyphenols to HSA were relatively high in comparison with other plants. A strong pos. correlation of binding properties and bioactivity of Momordica charantia was estimated One of the volatiles, namely citronellol, has key importance in respect of antidiabetic effect of Momordicacharantia Chinese variety. This study indicates pro-health preponderance of Chinese variety over Indian variety and confirms that steam cooking is in lines with the canons of safe food preparation

Li, Ang published the artcilePredictions of oxidation and autoignition of large methyl ester with small molecule fuels, Category: esters-buliding-blocks, the main research area is methyl ester surrogate fuel autoignition oxidation laminar flow reactor.

Biodiesel contains large Me esters including Me palmitate (MP), Me oleate (MO), Me linoleate (ML), etc. Long alkyl chains and asym. structures of these large Me esters lead to complexity in development of kinetic models. In this paper, surrogate fuels for large Me esters were proposed and developed. Surrogate models can be used to replace the detailed mechanisms of large Me esters in prediction of oxidation and autoignition properties. Key characteristics in combustion have non-linear relationships with fuel components in a neural network diagram, which indicates that surrogates with the same functional groups can exhibit similar combustion properties as large Me esters. In formulation of surrogate fuels, candidates consist of small species such as Me decanoate, n-hexadecane, Me trans-3-hexenoate, and 1, 4-hexadiene. To compare the oxidation properties, point-to-point exptl. validations were conducted in laminar flow reactor. Oxidation properties of surrogate and target fuels were in satisfactory agreements. Surrogate fuels not only successfully captured the discrepancies in reactivity of different Me esters, but also reproduced species concentrations of intermediate and products at various equivalence ratios. To test the performance in predicting autoignition characteristics, simulations based on surrogate models were compared with previous exptl. data. Surrogate models not only predicted ignition delay times at various pressure and equivalence ratios, but also reproduced the trends of apparent activated energy under different conditions. To sum up, oxidation and autoignition characteristics of large Me esters can be predicted by the combined kinetic model of small mol. compounds, which will have great potentials in the development of kinetic models for fuels with complicated mol. structures.

Stevenson, Keisean A. J. M. published the artcileThermodynamics-based modelling of gas chromatography separations across column geometries and systems, including the prediction of peak widths, Recommanded Product: Methyl decanoate, the main research area is thermodn modeling gas chromatog separation across column geometries system; peak width prediction; retention prediction; thermodynamic modeling.

Thermodn.-based models have been demonstrated to be useful for predicting retention time and peak widths in gas chromatog. and two-dimensional gas chromatog. separations However, the collection of data to train the models can be time consuming, which lessens the practical utility of the method. In this contribution, a method for obtaining thermodn.-based data to predict peak widths in temperature-programmed gas chromatog. is presented. Exptl. work to collect data for peak width prediction is identical to that required to collect data for retention time prediction using approaches that we have presented previously. Using this combined approach, chromatograms including retention times and peak widths are predicted with very high accuracy. Typical errors in retention time are < 0.5%, while errors in peak width are typically < 5% as demonstrated using polycycic aromatic hydrocarbons and a mixture containing compounds with aldehyde, ketone, alkene, alkane, alc., and ester functionalities.

Khatun, Habiba published the artcileCharacterization of freeze-dried, oven-dried and blanched house crickets (Acheta domesticus) and Jamaican field crickets (Gryllus assimilis) by means of their physicochemical properties and volatile compounds, Computed Properties of 110-42-9, the main research area is volatile compound Achete Gryllus freeze oven drying blanching.

Edible insects are repeatedly being considered as underutilized food candidate due to their high nutritional value. Although frequent acceptance of whole insects to consumer is still challenging, incorporation of insects in food as powder or paste has been suggested to increase their acceptability. Hence, Acheta domesticus and Gryllus assimilis were subjected to freeze drying, oven drying, and blanching to acquire a clear insight on the impact of the processing methods on the nutritional and phys. properties of both species. Result showed that these three methods had limited effects on the proximate composition, fatty acid and amino acid profile but had significant impact on other parameters for both species. Vitamin B12 in A. domesticus did not change but G. assimilis changed due to the treatment. Freeze drying showed better lightness (L* value) and lower browning index for both cricket species. Oven drying and blanching resulted in lower lipid oxidation values than freeze drying for both cricket species; though lipid oxidation was in all cases well below the rejection limit. Esters were the predominant group of volatile compound in freeze and oven-dried cricket while least amount of volatiles were found in blanched cricket. The volatiles resulted from fatty acid oxidation were higher in freeze-dried crickets, while Maillard reaction products were found in oven-dried samples. Although freeze drying showed higher color quality, oven drying exerted superior effect in terms of nutritional and flavor characteristics followed by blanching treatment.

European Food Research and Technology published new progress about Acheta domesticus. 110-42-9 belongs to class esters-buliding-blocks, name is Methyl decanoate, and the molecular formula is C11H22O2, Computed Properties of 110-42-9.
