Murti, Rihastiwi Setiya published the artcileThe effect of palm oil sulfatation time on fatliquor quality and finished leather product, Application of Methyl decanoate, the main research area is palm oil sulfatation fatliquor finished leather product quality.

Fatliquoring process is an important process in leather manufacturing as the process affects the properties of leather such as softness, oil content, tensile strength, elongation at break and tear strength. In this study, sulfated oil was made from palm oil by sulfatation process using 25% sulfuric acid (98% content) with variation of sulfatation times (0, 1, 2, 3, and 4 h). The study aimed to know the influence of sulfatation time on the production of sulfated oil to the quality of oil and finish leather produced. The results showed the sulfatation time affected the quality of sulfated oil and tanned leather. The optimum time for sulfatation process of palm oil was three hours. The quality of sulfated oil had water content of 6.47%, pH of 8, oil content of 81.28%, saponification number of 192.74%, total alkalinity of 0.25%, ash content of 2.77% and SO3 levels bond of 7.68%. The quality of finished leather were tensile strength of 286.50 N/mm2, elongation at break of 63.33%, softness of 3.92 mm and oil content of 10.15%.

Araujo, Maria Flavia Rodrigues Starling published the artcileSimultaneous thermal liquefaction of sugarcane bagasse and esterification with ethanol and fusel oil: One-Step process for biofuel production, Category: esters-buliding-blocks, the main research area is ethanol fusel oil biofuel thermal liquefaction sugarcane bagasse esterification.

Sugarcane bagasse is an abundant residue from the ethanol/sugar industries and its liquefaction can be a low-cost process for the production of liquid biofuels. However, the resulting biocrude has high acidity, which requires an upgrading before being used. In this study, ethanol and fusel oil, which is the heavy residue of ethanol distillation made up of higher alcs., were used as solvents for the liquefaction of bagasse. The 1:10 biomass:solvent ratio mixture was used at 300 °C for 30 min and (10 bar) N2 atmosphere. A mixture of both solvents was also tested to make a comparative study. The process with ethanol showed 72% bagasse conversion, but the best result showed 91% with fusel oil, producing a low biochar content (9%). After the distillation of the liquid product, a biocrude with high combustion heat (30.6 MJ.kg-1) and rich in esters was obtained. The results of GC/MS revealed the greater presence of esters with substituted isoamyl groups (51.2%) and, to a lesser extent, phenolic compounds (2.5%). The biochar has a higher heating value of 30 MJ.kg-1 and special thermal stability, suitable for application as a solid fuel. The biocrude was mixed with marine diesel (5%) and the properties of the mixture were evaluated, without relevant modifications. This innovative process showed the use of two residues, bagasse, and fusel oil, to produce a biofuel to be used with different types of diesel, with economic and environmental gains in a cycle economy for the ethanol industry.

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, Jianghua published the artcileEfficient production of medium-chain structured phospholipids over mesoporous organosulfonic acid-functionalized SBA-15 catalysts, Synthetic Route of 110-42-9, the main research area is phospholipid mesoporous organosulfonic acid silica functionalized catalyst.

It is highly desirable that efficient recoverable heterogeneous catalysts should be developed to replace the costly biocatalysts used in producing structured phospholipids (SPLs) with medium-chain fatty acids (MCFAs). Thus, mesoporous Pr and Ph sulfonic acid-functionalized SBA-15 materials synthesized via surface modification methods were investigated for the soybean lecithin interesterification with Me caprate or caprylate. The physicochem. properties of the synthesized solid acids were deeply studied by small-angle X-ray diffraction, SEM, transmission electron microscopy, Fourier transform IR and pyridine adsorption, etc. to build the possible structure-performance relationships. The results revealed that amounts of organosulfonic acid groups were successfully grafted onto the SBA-15 support, and most of the surface acid sites contained in the as-prepared organic-inorganic hybrid samples were assigned as strong Brönsted acid sites. Notably, the functionalized SBA-15 materials exhibited promising catalytic behaviors in producing MCFA-enriched SPLs under mild conditions (40°C, 6 h) when compared with com. Amberlyst-15 and typical phospholipases or lipases, mostly due to their high surface area, ordered structure and adequate Brönsted acid sites. Besides, the as-prepared materials could be easily recycled five times without obvious deactivation. This work might shed light on alternative catalysts for SPL production instead of the costly enzymes.

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.

Xu, Dan published the artcileSelective oxidation of alcohols to high value-added carbonyl compounds using air over Co-Co3O4@NC catalysts, HPLC of Formula: 110-42-9, the main research area is alc carbonyl compound cobalt tetraoxide carbon catalyst selective oxidation.

The sustainable catalytic transformation of alcs. to high value-added fine chems. is a significant and challenging research topic. Herein, a set of nitrogen-doped carbon encapsulated Co-based catalysts (Co-Co3O4@NC-T) were prepared by using low-cost dicyandiamide, glyoxal and cobalt nitrate as precursors. The obtained catalysts were utilized for the selective oxidation of alcs. to high value-added esters and carboxylic acids with air as the oxygen source and displayed wide applicability for the oxidation of both aromatic and aliphatic alcs. Based on the controlled experiments, the protective effect of N-doped carbon structure and the synergistic effect between Co core and Co3O4 species guaranteed the high reaction conversion and selectivity. Benefitting from heterogeneity and magnetism of the catalyst, it can be easily recycled and reused for long-term stability. Reasonable mechanisms of selective oxidation reaction were proposed through EPR anal. and controlled experiments The present work provides a facile strategy for potential large-scale preparation of heterogeneous catalyst for sustainable and green catalytic transformations.

Soudagar, Manzoore Elahi. M. published the artcileThe effects of graphene oxide nanoparticle additive stably dispersed in dairy scum oil biodiesel-diesel fuel blend on CI engine: performance, emission and combustion characteristics, Synthetic Route of 110-42-9, the main research area is graphene oxide nanoparticle biodiesel diesel blend engine combustion emission.

In the present investigation, the effects of graphene oxide nanoparticles on performance and emissions of a CI engine fueled with dairy scum oil biodiesel was studied. Nanofuel blend was prepared by dispersing graphene oxide in varying quantities in dairy scum oil Me ester (DSOME)-diesel blend. Sodium dodecyl sulfate (SDS) was used as a surfactant for a steady dispersion of graphene oxide nanoparticles in the fuel blends. The dispersion and homogeneity were characterized by UV-visible spectrometry. An ideal graphene-to-surfactant ratio was defined, highest absolute value UV-absorbency was seen for a mass fraction of 1:4. The concentration of surfactant above or below this ratio resulted in reduction in the stability of dispersion. Graphene oxide nanoparticles were amalgamated with dairy scum oil biodiesel at proportions of 20, 40 and 60 ppm using ultrasonication technique. Experiments were performed at a constant speed and varying the brake power and load condtions. The results were notable enhancements in the performance and emissions characteristics, the brake thermal efficiency improved by 11.56%, a reduction in brake specific fuel consumption by 8.34%, unburnt hydrocarbon by 21.68%, smoke by 24.88%, carbon monoxide by 38.662% for the nanofuel blend DSOME2040 and oxides of nitrogen emission by 5.62% for fuel DSOME(B20). Similarly, the addition of graphene nanoparticles in DSOME fuel blends resulted in significant reduction in the combustion duration, ignition delay period, improvement in the peak pressure and heat release rate at maximum load condition. Finally, it is concluded that nano-graphene oxide nanoparticles can be introduced as a suitable substitute fuel additive for dairy scum oil biodiesel blends to enhance the overall engine performance and emissions characteristics.

Tchouakeu Betnga, Prudence Fleur published the artcileImpact of closure material on the chemical and sensory profiles of grappa during storage in bottle, COA of Formula: C11H22O2, the main research area is grappa bottle storage closure material chem sensory profile.

The effects of different closure materials for stoppers were evaluated on the volatile and non-volatile composition and sensory profile of an Italian grappa (a fermented grape pomace brandy) stored in bottles for 12 mo. With respect to tech. stoppers, common micro-granulated cork stoppers increasingly absorbed the distillate over storage and released more intense non-volatile compounds determining the browning of grappa. Higher alcs. and esters were the main compounds contributing to the volatile profile of grappa and were correlated to pungent and floral/fruity aromas, resp. Esters and alcs. from C3 to C8 (Et acetate, Et hexanoate, 3-methyl-1-butanol acetate, 2-methyl-1-propanol, 3-methyl-1-butanol and 1-hexanol) decreased from three to six months of storage and further increased. Instead, the esters Me decanoate, Et decanoate and Et dodecanoate increased from three to six months and then decreased. The sensory profile of grappa was also affected by the common micro-granulated cork stopper after one-year of storage in bottle as determined by the trained panel.

Keshala, K. Kasuni published the artcileBioactivities and GC-MS profiling of Malewana Madhumeha Choorna polyherbal hot infusion, Category: esters-buliding-blocks, the main research area is Malewana madhumeha choorna phytochem hypoglycemia gas chromatog mass spectrometry.

Although traditional practitioners prescribe Malewana Madhumeha Choorna hot infusion (MMCHI) in Sri Lanka to combat diabetes, its antidiabetic properties have yet to be explored. We examined the in vitro hypoglycemic activity of MMCHI using α-amylase, α-glucosidase enzymes, and glucose uptake assays. Further, in vitro antioxidant activity was determined using DPPH (2,2 diphenyl-1-picrylhdrazyl) and H2O2 free radical scavenging activities. To identify the phytochems. present in the hot infusion, we conducted solvent-solvent fractionation (hexane, chloroform, Et acetate, methanol) procedures and subjected them to gas chromatog.-mass spectrometry (GC-MS). Both MMCHI and fractions exhibited a dose-dependent inhibition of glucose uptake and the enzymes α-amylase and α-glucosidase. The hot infusion exhibited enzyme inhibitory activities more or less similar to the standard drug acarbose. Enzyme inhibition was especially pronounced with α-amylase. Glucose uptake by MMCHI was more potent than that of the standard drug, especially at the 125μg/mL dose. Strong antioxidant scavenging activity, comparable to that of the standard drug, was observed in the MMCHI, further indicating its antidiabetic potential. The presence of organic compounds and essential oils in the extract was responsible for potent antidiabetic activities via inhibition of α-amylase enzyme. Also, MMICH exhibited strong free radical scavenging abilities. The current study justifies the use of MMCHI to manage diabetes.

Li, Song published the artcileOne-pot hydrodeoxygenation of biomass furan derivatives into decane under mild conditions over Pd/C combined with phosphotungstic acid, Safety of Methyl decanoate, the main research area is furan hydrodeoxygenation decane production palladium carbon combined phosphotungstic acid.

One-pot hydrodeoxygenation (HDO) of biomass furan derivatives into long-chain alkanes remains unclear owing to the complicated reactions at high temperatures Here, Pd/C combined with phosphotungstic acid (HPW), a strong Bronsted solid acid promoter, was developed to produce decane under mild conditions through the one-pot HDO of δ-furfurylidenelevulinic acid (FDLA). A 93.16% sum yield of alkanes including 89.53% yield of decane was obtained under 3 MPa H2 at 170°C for 4 h. The ring-opening and HDO of furans are accomplished at preheating stage, which enable to clarify the complicated reaction pathway. In addition, exptl. validations and catalytic characterizations confirm that the synergistic effect of active acid-metal sites plays a critical role in the generation of alkanes via the formation and hydrogenolysis of lactone intermediates to aldehyde/alc. This work provides guidance for the one-pot HDO of biomass furan derivatives via the combination of metal catalyst and strong Bronsted solid acid under mild conditions.
