Catalytic valorization of lignin to liquid fuels over solid acid catalyst assisted by microwave heating was written by Zhou, Minghao;Sharma, Brajendra K.;Li, Jing;Zhao, Jiaping;Xu, Junming;Jiang, Jianchun. And the article was included in Fuel in 2019.Computed Properties of C9H12O3 The following contents are mentioned in the article:

In this study, three types of lignin feedstocks were introduced into the microwave assisted depolymerization process over solid acid catalysts. The effects of lignin structures, solvents and catalysts were investigated to improve bio-oil yields and properties. A common phenomenon was observed that the highest bio-oil yields were all obtained in methanol under optimal conditions with microwave heating. The highest bio-oil yield from alk. lignin, dealkaline lignin and lignosulfonate was 57.4%, 82.9% and 70.9% resp., all obtained in methanol. The promotional effect of methanol over HSZ-640 (or HSZ-660) in the depolymerization process was confirmed due to the higher polarity of methanol, and higher acidity of catalysts. The promotional effect on the elemental composition and HHV of bio-oil was observed, finding that HSZ-640 (or HSZ-660) exhibited to be effective to convert lignin to liquid fuels with higher HHV, and the HHV of obtained bio-oil increased to about 28-32 MJ/kg, confirming that hydrogenation/hydrodeoxygenation took place during the depolymerization This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Computed Properties of C9H12O3).

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. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Computed Properties of C9H12O3

Changes in chemical and sensory properties of Amarone wine produced by Penicillium infected grapes was written by Zapparoli, Giacomo;Lorenzini, Marilinda;Tosi, Emanuele;Azzolini, Michela;Slaghenaufi, Davide;Ugliano, Maurizio;Simonato, Barbara. And the article was included in Food Chemistry in 2018.Recommanded Product: 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

There is very little information on effects of Penicillium on aroma of passito wine. This study analyzed chem. composition and sensory properties of Amarone wines produced from withered grapes artificially contaminated by P. expansum or P. crustosum. Changes in properties of the two wines were evident by comparing wines obtained from healthy and Botrytis cinerea infected grapes used as controls. Penicillium infection affected primary and volatile composition of Amarone wine. Sensory profiles of these wines, obtained by descriptive anal., resulted in clear differences in the wines between themselves and the control wines. Partial least square regression anal. explained only partially the relationship between mols. and sensory descriptors, and showed the existence of complex interactions of compounds mainly involved in specific aroma attributes. GC-olfactive anal. showed a greater number of odor regions in P. crustosum wine compared to control wines. Useful insight was provided into understanding how Penicillium rotten grapes affect Amarone wine properties. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Recommanded Product: 4-Hydroxy-3-methoxyphenethanol).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: 4-Hydroxy-3-methoxyphenethanol

Identification of Bacillus strains producing glycosidases active on rutin and grape glycosidic aroma precursors was written by Haure, Maxime;Chi Nguyen, Thi Kim;Cendres, Aurelie;Perino, Sandrine;Wache, Yves;Licandro, Helene. And the article was included in LWT–Food Science and Technology in 2022.Computed Properties of C9H12O3 The following contents are mentioned in the article:

Most of the glycosidic aroma precursors in grape consist of diglycosides such as rutinoside. Yeast glycosidases have been extensively studied but their activity is limited to monoglucosidic precursors. Yet, there is no study about application of glycosidases active on rutinoside in grape. In this study, we screened Bacillus isolates for their glycosidase activities on rutin and grape aroma precursors. One Bacillus amyloliquefaciens and one Bacillus licheniformis strains produced extracellular glycosidases, active on both rutin and para-nitrophenol-α-L-rhamnoside. The specific rutinosidic activities were 6.2 and 4.1 pkat/mg resp., and supernatants were active on Muscat grape glycosidic aroma precursors. Both strains were able to release monoterpenoids and benzenoids. The most released monoterpenoid in grape pomace was neric acid, with 378μg/kg and the most released benzenoid was 2-phenylethanol, with 189μg/kg for B. licheniformis. These glycosidases are interesting tools to target rutinosidic glycosides in grape and can be applied as a new way for valorising grape pomace. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Computed Properties of C9H12O3).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters are also usually derived from carboxylic acids.

And the article was included in RSC Advances in 2019.COA of Formula: C9H12O3 The following contents are mentioned in the article:

The Machilus genus (Lauraceae) had been extensively utilized in folk medicine due to its broad range of bioactivities. In the present study, a series of chromatog. separation of the methanol extract of stems of M. philippinensis led to the identification of thirty eight compounds totally. Among these, biscinnamophilin (1), machilupins A-C (2-4), machilutone A (5), and machilusoxide A (6) were new compounds reported for the first time. In addition, 5 was characterized with a unprecedented carbon skeleton. Other known compounds, including the major compounds cinnamophilin (7) and meso-dihydroguaiaretic acid (8), are identified by comparison of their phys. and spectroscopic data with reported values. One of the reported compounds, cinnamophilin A (10), should be revised as dehydroguaiaretic acid (9) after careful comparison of all the ¹H and ¹³ C NMR data. Moreover, the neuroprotective activity of cinnamophilin (7) was examined in a primary cortical neuron culture and the results indicated that 7 was effective against glutamate induced excitotoxicity.

Absorption, Distribution, Metabolism, and Excretion of the Main Olive Tree Phenols and Polyphenols: A Literature Review was written by Galmes, Sebastia;Reynes, Barbara;Palou, Mariona;Palou-March, Andreu;Palou, Andreu. And the article was included in Journal of Agricultural and Food Chemistry in 2021.Application of 2380-78-1 The following contents are mentioned in the article:

A review. The effects of olive tree (poly)phenols (OPs) are largely dependent upon their bioavailability and metabolization by humans. Absorption, distribution, metabolism, and excretion (ADME) are fundamental for the nutritional efficacy and toxicol. impact of foods containing OPs. This review includes studies on the administration of hydroxytyrosol (HT), oleuropein (Ole), or other OPs and foods, products, or mixtures that contain them. Briefly, data from in vivo studies indicate that OPs are absorbable by intestinal cells. Both absorption and bioavailability depend upon each compound and/or the matrix in which it is contained. OPs metabolism begins in enterocytes and can also continue in the liver. Metabolic phase I mainly consists of the hydrolysis of Ole, which results in an increase in the HT content. Phase II metabolic reactions involve the conjugation of (poly)phenols mainly with glucuronide and sulfate groups. This review offers a complete perspective of the ADME processes of OPs, which could support the future nutritional and/or toxicol. studies in this area. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Application of 2380-78-1).

Controlled lignosulfonate depolymerization via solvothermal fragmentation coupled with catalytic hydrogenolysis/hydrogenation in a continuous flow reactor was written by Brandi, Francesco;Antonietti, Markus;Al-Naji, Majd. And the article was included in Green Chemistry in 2021.Application of 2380-78-1 The following contents are mentioned in the article:

Sodium lignosulfonate (LS) was valorized to low mol. weight (M_w) fractions by combining solvothermal (SF) and catalytic hydrogenolysis/hydrogenation fragmentation (SHF) in a continuous flow system. This was achieved in either alc./H₂O (EtOH/H₂O or MeOH/H₂O) or H₂O as a solvent and Ni on nitrogen-doped carbon as a catalyst. The tunability according to the temperature of both SF and catalytic SHF of LS has been sep. investigated at 150°C, 200°C, and 250°C. In SF, the minimal M_w was 2994 g mol^-1 at 250°C with a dispersity (D) of 5.3 using MeOH/H₂O. In catalytic SHF using MeOH/H₂O, extremely low M_w was found (433 mg gLS^-1) with a D of 1.2 combined with 34 mg gLS^-1. The monomer yield was improved to 42 mg gLS^-1 using dual catalytic beds. These results provide direct evidence that lignin is an unstable polymer at elevated temperatures and could be efficiently deconstructed under hydrothermal conditions with and without a catalyst. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Application of 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Application of 2380-78-1

Effect of Reaction Conditions on Catalytic and Noncatalytic Lignin Solvolysis in Water Media Investigated for a 5 L Reactor was written by Ghoreishi, Solmaz;Barth, Tanja;Hermundsgaard, Dag H.. And the article was included in ACS Omega in 2019.Formula: C9H12O3 The following contents are mentioned in the article:

The high content of oxygen in the lignin polymer and the prevalence of phenolic functional groups make the conversion of lignin to fuels and value-added products with well-defined chem. properties challenging. The lignin-to-liquid process using a water/formic acid reaction medium has been shown to convert the lignin polymer to monomers with a mol. weight range of 300-600 Da. The bio-oil comprises a complex mixture of monomeric phenols, aromatics, and aliphatic hydrocarbons with a high H/C and low O/C ratio. This study investigates the effect of the stirring rate, level of loading, and catalyst at 305 and 350 °C in a 5 L pilot scale reactor. The oil yields are found to be highest for experiments conducted using the maximum stirring rate, maximum level of loading, and Ru/Al₂O₃ catalyst with yields of more than 69 weight % on lignin intake. Goethite as a catalyst does not show good conversion efficiency at either reaction temperatures The carbon recovery is highest for products produced at 305 °C. Furthermore, results from solid phase extraction on a DSC-CN solid phase show that 65-92 weight % the bio-oils can be recovered as fractions separated based on polarity. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Formula: C9H12O3).

Toward an Increased Functionality in Oyster (Pleurotus) Mushrooms Produced on Grape Marc or Olive Mill Wastes Serving as Sources of Bioactive Compounds was written by Koutrotsios, Georgios;Kalogeropoulos, Nick;Kaliora, Andriana C.;Zervakis, Georgios I.. And the article was included in Journal of Agricultural and Food Chemistry in 2018.COA of Formula: C9H12O3 The following contents are mentioned in the article:

Pleurotus ostreatus, P. eryngii, and P. nebrodensis were cultivated on nonconventional substrates containing grape marc (GMC) or olive mill byproducts (OMB); wheat straw (WHS) served as control. GMC-based media demonstrated equal/better mushroom productivity than WHS for P. eryngii and P. nebrodensis, while the cultivation performance of P. eryngii was improved in OMB-based media. Both GMC and OMB substrates led to large increase of fruit-bodies content in phenolic acids, resveratrol, triterpenic compounds, and ergosterol; in particular, P. eryngii mushrooms presented significantly more total phenolics and exhibited much higher antioxidant activity (2- to 8-fold increase). Furthermore, substrates containing GMC or OMB presented up to 27% increase in mushroom β-glucans. Overall, Pleurotus species responded in a different and mostly substrate-specific manner by selectively absorbing organic compounds Phenolics and squalene content of substrates correlated very well with mushrooms antioxidant activity and ergosterol, resp.; the same was observed for triterpenics’ content of substrates and mushrooms.

Biotransformation of pungent constituents from ginger (Zingiber officinale Roscoe) by Colletotrichum gloeosporioides yields oxidative ortho-ortho coupling products was written by de Avila, Roberta Marques Dias;Toffano, Leonardo;Fernandes, Joao Batista;da Silva, Maria Fatima das Gracas Fernandes;de Sousa, Lorena Ramos Freitas;Vieira, Paulo Cezar. And the article was included in Biocatalysis and Biotransformation in 2022.SDS of cas: 2380-78-1 The following contents are mentioned in the article:

This work investigated the biotransformation of ginger constituents (zingerone, [6]-shogaol, [6]-gingerol, and methyl-[6]-gingerol) by the pathogenic fungus Colletotrichum gloeosporioides. Experiments were carried out with and without deuterium-labeled compounds The product metabolites were analyzed by liquid chromatog. coupled to tandem mass spectrometry and liquid chromatog. solid phase extraction-NMR. Substrates supplied to the fungus were incorporated into metabolic pathways mostly by oxidation reactions, including aromatic carbon-carbon coupling. Zingerone and [6]-gingerol biotransformation products included biphenol dimers. A biodegradation pathway for biphenol formation was proposed based on the presence of the intermediate 4-(2-hydroxyethyl)-2-methoxyphenol, commonly identified from [6]-gingerol and [6]-shogaol biodegradation This intermediate likely originates from a Baeyer-Villiger reaction followed by hydrolysis. The C-C coupling of mols. could result in phenolic oxidative ortho-ortho coupling, suggesting that biphenol dimers are products of C. gloeosporioides laccase catalysis. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1SDS of cas: 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. 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.
