Zhong, Yiliu published the artcileCombustion characteristics of aromatic-enriched oil droplets produced by pyrolyzing unrecyclable waste tire rubber, Product Details of C11H22O2, the main research area is aromatic oil droplet combustion pyrolyzing unrecyclable waste tire rubber.

The purpose of this work is to study the combustion characteristics of aromatic-enriched tire pyrolysis oil (TPO) produced from typical small vehicles and truck tires. Pyrolysis oils (NRTO: natural rubber tire oil and SRTO: synthetic rubber tire oil) from two raw radial tire materials were produced and condensed at 25 °C and 130 °C in a three-stage auger pyrolysis reactor under neg. pressure. Combustion particularities were acquired using a single-droplet suspension combustion device and evaluated by five different indicators: kinetics, flame shape, burning rates, flame stand-off ratio (FSR) and mass transfer parameters. It was found that TPO was a potential fuel with higher calorific value (40-44 MJ/kg) and lower combustion apparent activation energy (10-40 MJ/mol) than that of bio-oil and solid fuels. Oil produced from synthetic rubber and condensed at 25 °C exhibited higher stable burning rate (1.93 ± 0.03 mm2/s) than that of nature rubber pyrolysis oil. Comparing with traditional fuels, tire oil droplets displayed higher surface local heat transfer coefficient, but the mass transfer number (B â‰?2.5) and FSR (<3.1) under stable combustion conditions were much lower. The combustion behavior of TPO has partial similarity with unsaturated hydrocarbons and ester biofuels. The reported results support the well-characterized TPO condensates for subsequent atomized combustion in realistic industrial burners.

Shirshin, Konstantin K. published the artcileSpecific Organocatalysis in Amidation Reaction of Fatty Acid Methyl Esters with 3-(Dimethylamino)-1-propylamine, Safety of Methyl decanoate, the main research area is dimethylaminopropyl amine FAME organo catalytic amidation potential energy surface.

Comparison of various organic compounds such as glycols, amines and alkanolamines as organocatalysts in amidation of fatty acid Me esters with 3-(dimethylamino)-1-propylamine was made for the first time. It was exptl. detected that catalysts containing OH-groups (alcs., glycols, glycerol and aminoalcs.) influence the reaction rate. Moreover, catalytic effect is depending on the catalysts geometry significantly. 1,5-diols (e. g. diethylene glycol and diethanolamine) were found to accelerate the reaction more than other OH-groups containing additives. It was supposed, that this catalytic effect is caused by specific associative interactions between reactants and 1,5-diols, what was confirmed by quantum mechanics calculations Catalysts concentration effects on the reaction rate were also investigated.

Huang, Rui published the artcilePhysicochemical characterizations of microalgal methyl esters extracted with hexane and refined by vacuum distillation at different temperatures, Recommanded Product: Methyl decanoate, the main research area is hexane microalgal methyl ester vacuum distillation.

To prepare quality biodiesel from microalgal lipids in pilot-scale reactors, Me esters from microalgal cells were extracted with hexane after direct transesterification and then refined by vacuum distillation The refined Me esters were comprehensively characterized via gas chromatog.-mass spectrometry, Fourier transform IR spectroscopy, NMR, and thermogravimetric anal. The Me ester refined at 255°C-259°C was found to be the ideal fuel with a high fatty acid Me ester content of 94.6%, a low combustion activation energy of 42.1 kJ/mol, and a proper carbon-chain length distributed in C14-C18. Impurities extracted with hexane, such as alkanes and short-chain esters, were separated at 105°C-254°C owing to their low polarity and mol. weight Highly unsaturated Me esters with a long carbon-chain were collected at 260°C-280°C owing to their high b.p. Separation of alkanes, short-chain esters, and highly unsaturated Me esters through vacuum distillation effectively improved the properties of the Me esters extracted with hexane as a fuel and enhanced the economic feasibility of microalgal lipids.

Meng, Qinghui published the artcileA theoretical investigation on Bell-Evans-Polanyi correlations for hydrogen abstraction reactions of large biodiesel molecules by H and OH radicals, Application of Methyl decanoate, the main research area is hydrogen hydroxide biodiesel combustion activation energy enthalpy rate constant.

High-accuracy prediction of activation energies and enthalpies of reaction is theor. important while computationally challenging for accurately determining the kinetic para. of chem. reactions in biodiesel combustion. In practice, the Bell-Evans-Polanyi (BEP) correlations between the activation energy and the enthalpy of reaction play an important role in fast estimation with acceptable accuracy. In the present study, the BEP correlations for hydrogen abstraction reactions of biodiesel surrogates by H and OH radicals were theor. investigated by using high-level orbital-based and ONIOM-based methods. Reaction classes for these reactions were defined based on distinctive ele. inter. due to the complex characteristics of esters. Linear BEP correlations were established for each reaction class and validated by the high-level calculations, with deviations being less than 0.90 kcal/mol. The rate constants of some representative hydrogen abstraction reactions were calculated by using the BEP correlations and other approx. theories. These rate constants validate the BEP assumpn. of similar pre-exptl. factors for the reactions in the same group, and they are found to agree reasonably well with the available data in literature. Furthermore, improved predictn. to exptl. data were obtained by using an existing kinetic model of Me decanoate oxidation updated with the calculated rate constants The present BEP correlations are believed to provide effective solutions to some kinetic issues of real biodiesel combustion.

Jeon, Woo-Young published the artcileMicrobial production of sebacic acid from a renewable source: production, purification, and polymerization, SDS of cas: 110-42-9, the main research area is sebacate production plant oil engineering omega oxidation Candida; nylon 610 synthesis sebacate production C10 FAME biotransformation Candida.

Sebacic acid (SA) is an aliphatic ten-carbon dicarboxylic acid (1,10-decanedioic acid) with a variety of industrial applications, including the production of plasticizers, lubricants, cosmetics, and plastics. Currently, SA is produced exclusively from alk. pyrolysis of castor oil. Herein, we present an environmentally friendly green route of SA production from plant oil-derived sources by microbial ω-oxidation We genetically engineered β-oxidation-blocked diploid yeast Candida tropicalis, and created an effective microbial cell factory with an increase of 46% in SA production by overexpression of genes involved in ω-oxidation of hydrocarbons compared to the original strain. A biotransformation process of SA production from decanoic acid Me ester was developed to overcome the challenges of high-d. cell culture, substrate feed, substrate/intermediate toxicity, and foam generation. Fed-batch production of engineered C. tropicalis resulted in a molar yield of above 98%, a productivity of 0.57 g L-1 h-1, and a final titer of 98.3 g L-1 in a 5-L fermenter and the results were successfully reproduced using a larger scale 50-L fermenter. The produced SAs were successfully purified to >99.8% using acid precipitation and recrystallization Finally, bio-nylon 610 was successfully synthesized by polymerization of the purified SA with hexamethylenediamine and showed thermal properties very similar to those of com. available nylon 610. The processes developed and described in this study can be employed to produce and isolate SA for the synthesis of bio-nylons, using environmentally friendly procedures based on microbial biotransformation with potential industrial applications.

Wei, Zheng published the artcileVolatile aroma compounds in wines from Chinese wild/hybrid species, Safety of Methyl decanoate, the main research area is volatile aroma compound wine; Chinese wild/hybrid species; HS-SPME/GC-MS; PCA; volatile compounds; wines.

The volatile aroma compounds in wines produced from Chinese wild/hybrid species were investigated in comparison to wines from European grapes. Volatiles were extracted by headspace solid-phase micro-extraction and identified by gas-chromatog./mass-spectrometry. The identification of analyte was performed by a combination of the linear retention index approach with the comparison of the obtained mass spectra. A total of 98 peaks were tentatively assigned as wine aroma components, and 15 odorants can be found at concentrations above their odor threshold among the odor activity values (OAVs) of 46 compounds evaluated in all of the wines. The “”OAVsâ€?aroma wheels”” showed that the classes of aromatic series are first fruity, next herbaceous and roasty and no spicy and caramelized notes. Via principal component anal., all the grape germplasm studied could be divided into four groups: “”Jingsheng-1,”” “”Cabernet Gernischt,”” “”Beibinghong,”” and others, which exhibited distinctive aroma features, resp. Practical applications Chinese wild grape species have many desirable properties for wine grape breeding such as possessing strong resistant genes to fungal diseases and cold condition, especially after hybridization with European grapes. As an emerging wine country, wines from Chinese wild/hybrid species have achieved much success in the last few years. The chem. content and biol. properties have been studied extensively in many but there are a few studies in our knowledge about the wine tastes of these species. In this paper, the key odorants in wines produced from the Chinese grape species of V. amurensisRupr., V. davidiiFoex., and V. quinquangularisRehd. and its hybrids were characterized in comparison to wines produced from European grapes (V. vinifera). The findings will help to the further understanding of the key aroma components in the different Chinese grapevine germplasm, and make further efforts to enrich the wine types in the marketplace.

Demling, Philipp published the artcileSelection of a recyclable in situ liquid-liquid extraction solvent for foam-free synthesis of rhamnolipids in a two-phase fermentation, Application In Synthesis of 110-42-9, the main research area is liquid extraction solvent rhamnolipids two phase fermentation.

Excessive foaming causes instabilities in fermentation processes, particularly when producing biosurfactants, which can be overcome by intensifying the fermentation via insitu product recovery. A reductive, multi-step approach for selecting organic solvents for an in situ liquid-liquid extraction of rhamnolipids produced by recombinant Pseudomonas putida KT2440 was developed. (1) A database consisting of physicochem. parameters for 183 solvents was composed, allowing a pre-selection by setting resp. thresholds. (2) The number of solvents was reduced by evaluating their extraction efficiencies regarding rhamnolipids in cell-free cultivation broth and their impact on the growth of P. putida KT2440. (3) The most promising solvent was characterized regarding phase separation, pH-dependency of the extraction, and applicability of back-extraction for product recovery and solvent regeneration. The overall performance was assessed in two-phase (fed-)batch fermentations in lab-scale stirred-tank reactors. The solvent selection approach revealed Et decanoate to be a highly suitable and sustainable solvent for the in situ liquid-liquid extraction of rhamnolipids. During the final two-phase fed-batch fermentation, 30 g L-1 of produced rhamnolipids accumulated in the organic phase. Integrating extraction and increasing the partition coefficient by moderately lowering the pH prevented foaming during fermentation, thus resolving the initial process instability. Rapid phase separation and back-extractability allowed product recovery and solvent recycling. The here presented reductive, multi-step solvent selection approach was successfully applied to establish a two-phase fermentation producing rhamnolipids by engineered P. putida KT2440, resolving the foaming challenge. The approach can serve as a blueprint for selecting solvents for in situ liquid-liquid extractions in bioprocesses.

Park, Min Kyung published the artcileComparison of volatile profiles in Fagopyrum esculentum (buckwheat) soksungjang prepared with different starter cultures during fermentation, HPLC of Formula: 110-42-9, the main research area is Fagopyrum pentanoic acid dimethyl carbonate Bacillus Lactobacillus food fermentation; Fermentation; Partial least squares-discriminant analysis; Soksungjang; Soybean koji; Volatile profiles.

This study investigated the differences and changes in the volatile profiles of buckwheat soksungjang (BS) inoculated with multiple microbial starters (Lactobacillus brevis + Aspergillus oryzae, BS-LA vs. Lactobacillus brevis + Bacillus amyloliquefaciens, BS-LB) during fermentation using SPME coupled with GC-MS and partial least square-discriminant anal. BS samples fermented for 5 wk could be differentiated from other BS samples with shorter fermentation periods, and the BS-LA and BS-LB samples fermented for 5 wk were separated Acids, benzenes, and esters were main volatile compounds in both BS samples, however, their differences and changes were varied. The increase of 3-methylbutanoic acid was bigger in BS-LB than BS-LA, while the contents of 2- and 3-methylbutanal were relatively higher in BS-LA than BS-LB. Furthermore, the contents of esters of BS-LA significantly increased during fermentation These results indicate that the volatile profiles of BS samples depend on the fermentation periods and the combination of microbial starters.

Dandajeh, Hamisu Adamu published the artcileInfluence of combustion characteristics and fuel composition on exhaust PAHs in a compression ignition engine, COA of Formula: C11H22O2, the main research area is polycyclic aromatic hydrocarbon combustion compression ignition engine.

This paper reports an exptl. investigation into the effects of fuel composition on the exhaust emission of toxic polycyclic aromatic hydrocarbons (PAHs) from a diesel engine, operated at both constant fuel injection and constant fuel ignition modes. The paper quantifies the US EPA (United State Environmental Protection Agency) 16 priority PAHs produced from combustion of fossil diesel fuel and several model fuel blends of n-heptane, toluene and Me decanoate in a single-cylinder diesel research engine based on a com. light duty automotive engine. It was found that the level of total PAHs emitted by the various fuel blends decreased with increasing fuel ignition delay and premixed burn fraction, however, where the ignition delay of a fuel blend was decreased with use of an ignition improving additive the level of particulate phase PAH also decreased. Increasing the level of toluene present in the fuel blends decreased levels of low toxicity of two to four ring PAH, while displacing n-heptane with Me decanoate increased particulate phase adsorbed PAH. Overall, the composition of the fuels investigated was found to have more influence on the concentration of exhaust PAHs formed than that of combustion characteristics, including ignition delay, peak heat release rate and the extent of the premixed burn fractions.

Tharmasothirajan, Apilaasha published the artcileMicrobial Polyphenol Production in a Biphasic Process, HPLC of Formula: 110-42-9, the main research area is microbial polyphenol biphasic fermentation.

Microbial synthesis of aromatic compounds is generally limited by inherent product toxicity toward the producing cells. Here, in situ extractive strategies represent an efficient approach to avoid such toxic effects and to increase the overall process performance. We conducted a solvent screening to identify suitable organic solvents to develop a biphasic extractive strategy for microbial plant polyphenol production using Corynebacterium glutamicum. From 10 pre-selected organic solvents, tributyrin (TB) showed the best biocompatibility and was chosen for the biphasic extraction process due to its beneficial effect on partitioning and solubility of the plant polyphenol resveratrol. In bioreactors, biphasic cultivation with TB allowed for a product titer of 7.5 mM (1.71 g L-1) resveratrol with a volumetric productivity of 0.26 mM h-1 and a product yield of 0.92 mol mol-1. This biphasic cultivation procedure can be directly employed for the synthesis of other aromatics with similar properties using C. glutamicum.
