This work studied the fractionation of sugarcane bagasse via Organosolv treatment using isopropanol/water in the presence of Raney-Ni and molybdenum carbide catalysts (Bulk Mo2C and Mo2C supported on activated carbon (AC) or Al2O3). The degree of delignification, the bio-oil and solid residue composition depended on the type of catalyst. A partial extraction of hemicellulose occurred followed by depolymerization, resulting in a product distribution that depended on the catalyst. Raney-Ni catalyst promoted the formation of diols and triols, while xylose, furfural, and furan were mainly produced by Mo2C based-catalysts. The Organosolv treatment without catalyst and in the presence of bulk Mo2C produced a bio-oil containing mainly 2,3-dihydrobenzofuran. Mo2C/AC and Mo2C/Al2O3 are promising catalysts for the fractionation of sugarcane bagasse that produced a bio-oil with higher yield to substituted methoxyphenols and a solid residue more easily hydrolyzed by cellulases, producing higher yield to glucose than Raney-Ni catalyst.

Secondary compounds in higher plants have great diversity in terms of biol. activity. Most of them are used for the defense by plants. This study aims to investigate the effects of benzoic acid, salicylic acid, and Persica vulgaris Mill. (Peach) on the germination of the seeds of cultivated plants such as Triticum aestivum L. (wheat), Zea mays L. (corn), Cicer arietinum L. (chickpea), as well as weeds such as Lepidium campestre (L.) R.Br. and Convolvulus arvensis L. Method 1, in which benzoic acid, salicylic acid, and Persica vulgaris Mill. are added to the germination environment at different doses, and Method 2, in which they are mixed with the irrigation water at the specified doses, have been employed in this study. As a result of this study, it has been determined that the leaf extract of P. vulgaris Mill., Benzoic acid, and salicylic acid prevent the growth of the root and stem in all seeds at high doses in both methods, and they increase the growth at low doses. According to the GC-MS results of the leaf extract of P. vulgaris Mill., benzoic acid has been determined to be at the highest rate. No difference has been found between months as a result of the HPLC anal. of the amounts of benzoic acid. The determination of neg. effects of benzoic acid, salicylic acid, and peach leaf extract both on cultivated plants and weeds at high doses will repress the development of cultivated plants as well as weeds. Growing cultivated plants in places with peach trees may decrease the yield. The leaves should not be let decompose on the soil in defoliation season, and fallen leaves should be collected. Not collecting all of the leaves and leaving some of them may increase the development of weeds in the surrounding area since it may cause a low dose effect.

Sorbitol is a highly available and functionalized polyalc., with vast industrial usages and with great potential for fuel cells application. However, few studies were done regarding its electrochem. oxidation Monometallic Au, Pt and PtAu with different compositions from Pt-rich (such as Pt85Au15) to Au-rich (Pt10Au90) nanomaterials were synthesized. Several parameters like sorbitol and KOH concentration, scan rate, charge-transfer resistance, and temperature were tested. According with the physicochem. characterization, average particle sizes from 5.6 to 6.5 nm were found for all electrocatalysts, while Pt at. percentages of 85, 60, 40, and 10% were obtained. XPS revealed shifts in Pt 4f and Au 4f core-levels related to electron d. changes by the interaction between these elements and as a result, the electrocatalytic properties for the sorbitol electrooxidation reaction (SOR) were modified. The PtAu nanomaterials presented an increase of the c.d. with the raise of the KOH and sorbitol concentrations, being Pt40Au60/C the most active electrocatalyst displaying 40 mA mg-1 at 0.1M sorbitol in 2 M KOH with an onset potential of -0.50 V vs. normal H electrode. This onset potential value was more neg. to that typically reported for other polyols like glycerol and ethylene glycol. The reaction pathway of Pt/C, Au/C and Pt40Au60/C was followed by chromatog. and spectroscopic techniques, finding that the complex surfaces of these electrocatalysts were capable to carry the SOR via several electrons (from 2 to 24 e). In this manner, the high electrocatalytic activity of Pt40Au60/C was attributed to the electron d. changes that promote a higher electron transfer forming shorter-chain byproducts.

We investigated the mechanism of a cascade coupling reaction between 1,3-dihydroxyacetone (DHA) and formaldehyde using d. functional theory (DFT) calculations Based on our exptl. results, and in contrast to the previously proposed reaction pathway, we propose the following pathway: (i) the isomerization and dehydration of DHA to an enolate, (ii) an aldol reaction between the enolate and formaldehyde, (iii) the formation of a five-membered ring, and (iv) a proton transfer to form α-hydroxy-γ-butyrolactone (HBL). Consideration of the thermodn. stability of each substrate enabled us to suggest the most likely pathway, and the construction of a transition state model helped us to clarify the origin of the observed product selectivity.

Abstract: The leaves and petioles of Paulownia elongata x fortunei are residual fractions from the tree plantations com. destined to the production of wood and their valorization could contribute to the rational utilization of this resource. The saccharidic fraction is the most abundant in both parts of the plant and the sugar profile is very similar, but the ethanol extractives are more abundant in leaves. Non isothermal processing was selected since it provided better results than isothermal extraction with shorter times. For this reason, optimization of autohydrolysis under non isothermal operation (140-240°C) was performed for both materials: leaves and petioles. The final autohydrolysis temperature highly influenced the saccharidic, proteic, phenolic and volatile composition of the extracts Operating under selected conditions leaves provided extracts with more antioxidant compounds than petioles. The proposed technol. provides a variety of com. valuable components, which could contribute to the integral use of this energetic crop following a biorefinery approach.

Because it is undisputable that lignin depolymerization is a must to make the biorefinery concept economically feasible, several efforts are put toward it; however, a lot of catalyst designing is required to achieve efficient depolymerization activities. In this work, we show a systematic approach in the synthesis and characterization of ionic liquids (ILs) with varying combinations of cations (imidazole, benzimidazole, phosphonium, and ammonium) and anions (HSO4, PTS (p-toluenesulfonate), Cl, H2PO4, SnCl3, FeCl4, and CuCl3) for the depolymerization of lignin into low-mol. weight aromatic fractions (<220 g/mol) under mild reaction conditions (120 °C, 1 h, ambient pressure). In a methodical approach, effects of various reaction parameters such as temperature (70-170 °C), time (15-360 min), pressure (N2, 0.5-3 MPa), solvents and substrate, and so forth were studied to achieve best activity. Among all the catalysts, IL with the imidazolium cation and HSO4 as the anion showed best activity (78% yield). Subsequent to depolymerization, three aromatic monomers (5 wt % pure vanillin) were isolated using flash column chromatog. These aromatic monomers were characterized using gas chromatog. (GC), GC-mass spectrometry, and NMR techniques for their purity. Hammett acidity functions (H0) of ILs were measured using UV-vis photo-spectroscopy, and values are correlated with lignin depolymerization results. Lignin and tetrahydrofuran-soluble products were thoroughly characterized using assorted physicochem. techniques such as NMR (1H and 13C), gel permittivity chromatog., thermogravimetric anal., and so forth. The catalyst was recycled up to six runs and showed similar results in consecutive reactions.

Designing of efficient catalyst for the valorization of lignin is a topic of long neglect due to intrinsic properties of lignin. We show designing of an efficient, stable and recyclable Immobilized-Bronsted acidic ionic liquid (I-BAIL), which was further used as a solid acid catalyst for the depolymerization of lignin. The synthesized I-BAIL catalyst with sulfonic acid (-SO3H) groups was found to be stable until 250°C and has 42.2 weight% loading of BAIL anchored on silica framework. The detailed characterization (elemental, Thermogravimetric anal., Fourier transformation-IR, NMR) of catalyst disclosed formation of strong covalent bond between Si and carbon of BAIL, which in turn is responsible for achieving a stable catalyst. The catalyst could successfully depolymerize range of lignin substrates with high mol. weight (60000 Dalton) at 200°C in 1 h to achieve 90% yield of THF soluble products with good mass balance. The formation of products and correlation of products with lignin was achieved with the help of NMR, gel permeation chromatog., gas chromatog., gas chromatog.mass spectrometry, high performance liquid chromatog. etc.

Abstract: A suite of untargeted methods has been applied for the characterization of aerosol from the Tobacco Heating System 2.2 (THS2.2), a heated tobacco product developed by Philip Morris Products S.A. and commercialized under the brand name IQOS. A total of 529 chem. constituents, excluding water, glycerin, and nicotine, were present in the mainstream aerosol of THS2.2, generated by following the Health Canada intense smoking regimen, at concentrations ≥ 100 ng/item. The majority were present in the particulate phase (n = 402), representing more than 80% of the total mass determined by untargeted screening; a proportion were present in both particulate and gas-vapor phases (39 compounds). The identities for 80% of all chem. constituents (representing > 96% of the total determined mass) were confirmed by the use of authentic anal. reference materials. Despite the uncertainties that are recognized to be associated with aerosol-based untargeted approaches, the reported data remain indicative that the uncharacterized fraction of TPM generated by THS2.2 has been evaluated to the fullest practicable extent. To the best of our knowledge, this work represents the most comprehensive chem. characterization of a heated tobacco aerosol to date.

The aim of this paper was to characterize the complete volatile profile of Conciato Romano cheese, a traditional Italian product aged in a mixture of olive oil, wine, and spices, and its modification during ripening, by using SPME sampling and GC/MS anal. of volatiles and considering the rind and body parts sep. Seventy-six volatile compounds were identified, belonging to chem. classes of acids (8), aldehydes (3), alcs. (14), esters (36), ketones (9), hydrocarbons (1), and terpenes (5). Acids and esters represented the most important chem. classes and are originated from lipolysis and hydrolysis of triglycerides. Aging caused dramatic changes in volatile compounds, particularly on the cheese rind, where the amount of esters, acids, alcs., and ketones was found particularly abundant at 8 mo of aging. Interesting differences were found in volatile headspace composition depending on the external or inner parts. The higher complexity in volatile profile of aged cheese was attributed both to the aging process and tanning mixture Sensory anal. resulted in higher perception of “sweet” and “stickiness” and significantly lower olfactory persistence in fresh product, while higher values for “salty,” “spicy,” and “persistent” were found in aged ones. Practical applications: The results of our research can be useful to deepen knowledge of cheese volatile compounds and for a better understanding of the interactions between cheese aging and the use of a particular tanning mixture (olive oil, red wine, and spices), used in the Conciato Romano cheese. It can be used for a chem. characterization of the peculiarity found from sensory assessment of this cheese, as well as for control organisms, if further research would confirm the presence of volatile compounds as mol. markers. Finally, industry can take advantage of our research for possible future certifications of Conciato Romano as a Protected Designation of Origin. Conciato Romano, a typical and traditional Italian cheese, was studied to report its complete volatile profile by using the SPME-GC-MS technique. The volatile compounds were studied both in fresh and in 6- and 8 mo-aged cheese, by sep. analyzing the rind and body of the product.
