Hydrothermal liquefaction (HTL) of spruce wood was performed without and with the use of a potassium fluoride-doped alumina catalyst (KF/Al₂O₃) in a bench-top reactor. HTL runs were performed at 250, 300, and 350°C with residence times of 15, 30, and 60 min. The effects of the catalyst at different catalyst loadings (in concentrations from 10 to 40 wt % of the lignocellulosic biomass) on the bio-oil and solid residue yields as well as their properties were investigated. The use of the catalyst increased the bio-oil yields over twofold and reduced char yields. Gas chromatog.-mass spectrometry anal. revealed that the bio-oil from the noncatalytic and catalytic runs consisted of aldehydes, ketones, phenols, acids, and esters. Among these components, phenolic compounds were dominant in both the noncatalytic and catalytic runs. The relative yields of phenolic compounds increased with catalyst use. The highest heating value was estimated to be approx. 29 MJ/kg. The b.p. distributions of the bio-oils from both runs revealed that the total naphtha fraction (light and heavy) was comparable to that of crude oil. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Related Products of 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Production of phenolic chemicals from hydrolysis lignin via catalytic fast pyrolysis was written by Paysepar, Hooman;Venkateswara Rao, Kasanneni Tirumala;Yuan, Zhongshun;Shui, Hengfu;Xu, Chunbao. And the article was included in Journal of Analytical and Applied Pyrolysis in 2020.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

Catalytic fast pyrolysis of hydrolysis lignin was investigated in a drop-tube fixed bed reactor at different temperatures ranging between 400-800°C using zeolite X as a catalyst for the production of phenolic chems. The yield of low mol. weight monomeric phenolics increased considerably while increasing the pyrolysis temperature from 400°C to 450°C, but decreased with further increasing the pyrolysis temperature Zeolite X remarkably increased the yield of monomeric phenolic compounds in the catalytic fast pyrolysis of hydrolysis lignin at all temperatures (400-800°C) compared to fast pyrolysis. No significant changes were observed in the catalyst properties (crystallinity and textural structure) during fast pyrolysis of lignin. The superb activity of the zeolite X catalyst might be owing to its strong acidity and low pore volume Under the best reaction conditions tested in this study (450°C, with zeolite X catalyst), the bio-oil yield was 50.5% in relation to the dry lignin, and the content of monomeric phenolics (mainly guaiacol, syringol, 4-methoxy-3-(methoxymethyl) phenol and metoxyeugenol) was 146.2 mg/g of bio-oil.

Phenolic profile of oils obtained from “horchata” by-products assisted by supercritical-CO₂ and its relationship with antioxidant and lipid oxidation parameters: Triple TOF-LC-MS-MS characterization was written by Rosello-Soto, Elena;Barba, Francisco J.;Lorenzo, Jose M.;Munekata, Paulo E. S.;Gomez, Belen;Molto, Juan Carlos. And the article was included in Food Chemistry in 2019.Formula: C9H12O3 The following contents are mentioned in the article:

In this study, the effect of different supercritical CO₂ (SC-CO₂) pressures (10-40 MPa) on phenolic compounds extraction in oils obtained from “horchata” byproducts was evaluated, and the results were compared to those obtained after conventional oil extraction (CE). Moreover, the relationship between the individual phenolic compounds and the total antioxidant capacity as well as oil oxidative quality parameters was compared. The phenolic profile and contents were largely influenced by extracting conditions. The main phenolic compound obtained by SC-CO₂ was the isohydroxymatairesinol, particularly at 30 and 40 MPa, while 3-vinylphenol was the predominant compound in oils extracted by CE procedure. Increasing SC-CO₂ extraction pressures enhanced the extraction of phenolic compounds, along with improving the antioxidant capacity and oxidative quality of extracted oil. The principal component anal. indicated that the main phenolic compounds associated with TEAC values were those extracted by SC-CO₂, which were inversely correlated to oxidative indexes.

Increased intestinal permeability in older subjects impacts the beneficial effects of dietary polyphenols by modulating their bioavailability was written by Hidalgo-Liberona, Nicole;Gonzalez-Dominguez, Raul;Vegas, Esteban;Riso, Patrizia;Del Bo, Cristian;Bernardi, Stefano;Peron, Gregorio;Guglielmetti, Simone;Gargari, Giorgio;Kroon, Paul Antony;Cherubini, Antonio;Andres-Lacueva, Cristina. And the article was included in Journal of Agricultural and Food Chemistry in 2020.Formula: C9H12O3 The following contents are mentioned in the article:

Polyphenols have great potential in regulating intestinal health and ameliorating pathol. conditions related to increased intestinal permeability (IP). However, the efficacy of dietary interventions with these phytochems. may significantly be influenced by interindividual variability factors affecting their bioavailability and consequent biol. activity. In the present study, urine samples collected from older subjects undergoing a crossover intervention trial with polyphenol-rich foods were subjected to metabolomics anal. for investigating the impact of increased IP on the bioavailability of polyphenols. Interestingly, urinary levels of phase II and microbiota-derived metabolites were significantly different between subjects with healthier intestinal barrier integrity and those with increased IP disruption. Our results support that this IP-dependent impaired bioavailability of polyphenols could be attributed to disturbances in the gut microbial metabolism and phase II methylation processes. Furthermore, we also observed that microbiota-derived metabolites could be largely responsible for the biol. activity elicited by dietary polyphenols against age-related disrupted IP. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Formula: C9H12O3).

Rapid biosynthesis of phenolic glycosides and their derivatives from biomass-derived hydroxycinnamates was written by Zhao, Mingtao;Hong, Xulin;Abdullah;Yao, Ruilian;Xiao, Yi. And the article was included in Green Chemistry in 2021.HPLC of Formula: 2380-78-1 The following contents are mentioned in the article:

Biomass-derived hydroxycinnamates (mainly including p-coumaric acid and ferulic acid), which are natural sources of aromatic compounds, are highly underutilized resources. There is a need to upgrade them to make them economically feasible. Value-added phenolic glycosides and their derivatives, both belonging to a class of plant aromatic natural products, are widely used in the nutraceutical, pharmaceutical, and cosmetic industries. However, their complex aromatic structures make their efficient biosynthesis a challenging process. To overcome this issue, we created three novel synthetic cascades for the biosynthesis of phenolic glycosides (gastrodin, arbutin, and salidroside) and their derivatives (hydroquinone, tyrosol, hydroxytyrosol, and homovanillyl alc.) from p-coumaric acid and ferulic acid. Moreover, because the biomass-derived hydroxycinnamates directly provided aromatic units, the cascades enabled efficient biosynthesis. We achieved substantially high production rates (up to or above 100-fold enhancement) relative to the glucose-based biosynthesis. Given the ubiquity of the aromatic structure in natural products, the use of biomass-derived aromatics should facilitate the rapid biosynthesis of numerous aromatic natural products. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1HPLC of Formula: 2380-78-1).

Electron transfer plays a vital role in drug metabolism and underlying toxicity mechanisms. Currently, pharmaceutical research relies on pharmacokinetics (PK) and absorption, distribution, metabolism, elimination and toxicity (ADMET) measurements to understand and predict drug reactions in the body. Metabolic stability (and toxicity) prediction in the early phases of the drug discovery and development process is key in identifying a suitable lead compound for optimization. Voltammetric methods have the potential to overcome the significant barrier of new drug failure rates, by giving insight into phase I metabolism events which can have a direct bearing on the stability and toxicity of the parent drug being dosed. Herein, we report for the first time a data-mining investigation into the voltammetric behavior of reported drug mols. and their correlation with metabolic stability (indirectly measured via t1/2), as a potential predictor of drug stability/toxicity in vivo. We observed an inverse relationship between oxidation potential and drug stability. Furthermore, we selected and prepared short- (<10 min) and longer-circulation (>2 h) drug mols. to prospectively survey the relationship between oxidation potential and stability.

Lignin, which is biosynthesized through oxidative radical polymerization from primary monolignols during plant growth, represents the most abundant source of renewable aromatic resources. The search for efficient and selective catalysts for the production of monolignols and their corresponding unsaturated derivatives from the direct depolymerization of lignin is of great interest and importance, as such products are important platform chems. for the synthesis of natural products, pharmaceuticals, and functional materials. We report herein the first case of a supported molybdenum catalyst that functions as an efficient and selective catalyst for the fragmentation of woody lignocelluloses, leading to monolignols and ethers in high yields with high selectivity. Hydrogenation of the side chain and recondensation were not observed, suggesting that etherification acts as a new stabilization mechanism in the current Mo catalytic system. The (hemi)cellulose components were well preserved and amenable to valorization via enzymic hydrolysis and chemocatalytic conversion. This method constitutes an economically responsible pathway for lignin valorization as well as fractionation and sequential utilization of all of the biomass components.

The aim of this work was to research the relationship between volatile composition of Petit Verdot red wines and the fermentation temperature Winemaking process was carried out at 17°C, 21°C, and 25°C temperatures Solid-phase extraction (SPE) and gas chromatog.-mass spectrometry (GC-MS) were used to analyze volatile compounds The odor activity values (OAVs) from the different compounds were classified into seven odorant series that describe the aroma profile (fruity, floral, green/fresh, sweet, spicy, fatty, and other odours). The value of each aromatic series was obtained by adding the OAVs of the volatile compounds to each series. The volatile composition was significantly affected by the temperature of the fermentation In general, the increase in the fermentation temperature of La Mancha Petit Verdot red wines from 17 to 25°C produced an increase in the concentration of volatile aroma compounds The highest aroma contributions to Petit Verdot wine were fruity, sweet and floral series, followed by fatty and spicy series, regardless of fermentation temperature The highest values of aromatic series were found in wines fermented at 21°C. The results of this work show that changes in the fermentation temperature of wines can have a significant impact on their volatile compound profile.
