Microwave assisted liquefaction (MAL) of alkali lignin in ethylene glycol (EG) in the presence of hydrazine was carried out using response surface methodol. Dielec. properties of mixtures of lignin/EG at different hydrazine concentrations were determined to enhance the understanding of the MAL process. MAL parameters were hydrazine concentration (1-3%), temperature (100-180 °C), time (5-45 min) with the maximum microwave heating power limited to 750 W. Lignin/EG ratio was fixed at 1 g:10 mL. Dielec. properties were significantly influenced by hydrazine concentration and temperature Major products from the liquefaction process (as % of peak areas) were grouped into guaiacol and derivatives (17-42%), Nitrogen compounds (0-27%), and Hydroxylated products (8-22%), and their yields were modelled with polynomial equations. Product yields were significantly influenced by process parameters. Optimum parameters for maximizing yields of guaiacol and nitrogen containing compounds were 0.5%, 180 °C, 25 min and 2.5%, 130, 25 min for hydrazine concentration, temperature, and time, resp. Low hydrazine concentration increases guaiacol yield at higher temperatures, indicating that at high temperatures hydrazine behaves as a hydrogen donor for lignin liquefaction. The yield of nitrogen containing compounds increases at relatively low temperatures and high concentration of hydrazine. Apart from playing the resp. roles of liquefaction solvent and hydrogen donor, EG and hydrazine also take part in the reaction thereby significantly modifying the composition of reaction products. A mechanistic reaction mechanism was proposed to explain the formation of the liquefaction products. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Synthetic Route of C9H12O3).

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 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.Synthetic Route of C9H12O3

Degradation of most of the lignocellulose-rich agricultural residue in the cold regions of China is limited due to the cold climate. Lignin is the main component of lignocellulose, and the effective degradation of lignin is one of the most crucial processes in degrading lignocellulose. Psychrotrophic lignin-degrading bacteria and cold adapted ligninolytic enzymes have promising potential for the degradation and transformation of lignin, which are conducive to the resource utilization of lignocelluloses and energy-saving production under cold conditions. In this study, a newly psychrotrophic bacterial strain, Arthrobacter sp.C2, was isolated. The optimal enzyme activity conditions and lignin degradation pathways of C2 were investigated using sodium lignin sulfonate as substrate. The optimal conditions for enzyme activity included an initial pH of 6.74, a temperature of 14.9°C, an incubation time of 6.87 days, and an inoculum size of 2.24%. Under the optimal conditions, the lignin peroxidase and manganese peroxidase activities and the degradation rate reached 29.8 U/L, 56.4 U/L and 40.1%, resp. The biodegradation products including acids, phenols, aldehydes and alcs. were analyzed by gas chromatog.-mass spectrometry and Fourier transform IR spectroscopy. Further, the potential degradation pathways were proposed according to the results obtained in this study and those presented in the relevant literature. This study not only provides valuable psychrotrophic strain resources for the sustainable utilization of lignocellulose in cold regions, but also supplies potential application options for energy-saving production of useful chems. using cold adapted enzymes.

Catalytic pyrolysis of lignin using low-cost materials with different acidities and textural properties as catalysts was written by Han, Tong;Ding, Saiman;Yang, Weihong;Joensson, Paer. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2019.Formula: C9H12O3 The following contents are mentioned in the article:

Catalytic fast pyrolysis of lignin was performed using low-cost materials with different acidities and textural properties as catalysts in the present work. The main focus is to understand the role of low-cost catalysts in the fast pyrolysis of lignin. The four most commonly used low-cost catalysts, ilmenite (FeTiO₃), bentonite (Al-Si-OH), activated carbon (AC) and red mud (RM), were selected. The results show that bentonite, red mud and activated carbon effectively enhance the dehydration reaction, which is regarded as the dominant way to eliminate oxygen during the pyrolysis process, due to the existence of strong acidic sites. However, only activated carbon is found to be effective in promoting the production of monocyclic aromatic hydrocarbons (MAHs). Two metallic catalysts, i.e., bentonite and red mud, have strong acidities but quite low surface areas and less porous structures. Therefore, the dehydrated intermediates produced are especially easy to repolymerize to form char or coke without the restriction of obtaining a porous structure during the pyrolysis process. Activated carbon has not only a certain acidity but also a rich porous structure. Lignin fast pyrolysis-derived oxygenates can diffuse and react on the well-dispersed active sites within the pores of activated carbons. The catalytic performance of the activated carbon are supposed to be determined by the pore size. Only pores of similar size to lignin fast pyrolysis-derived oxygenates (0.6-1 nm) seems to be effective for the production of MAHs. Pores larger or smaller than lignin fast pyrolysis-derived oxygenates both tend to cause coke deposition rather than MAHs formation. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Formula: 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. Polyesters are important plastics, with monomers linked by ester moieties. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Formula: C9H12O3

Water Transport Polymers: Structure/Property Relationships of a Series of Phosphazene Polymers was written by Stone, Mark L.;Orme, Christopher J.;Peterson, Eric S.;Bauer, William F.;Stewart, Frederick F.;Harrup, Mason K.;Luther, Thomas A.;Klaehn, John R.;Wey, John E..

A study was undertaken to explore the water passing properties of a series of phosphazene polymers vs. the attached pendant group structure. Pendant groups containing different numbers of ethyleneoxy groups were synthetically attached to the backbone of phosphazene polymers. Phosphazene polymers facilitate these types of studies because, during their synthesis, the polymer backbone is formed first and then the desired pendant groups are attached through nucleophilic substitution. For these studies, four polymer series were synthesized and tested for their water passing properties. The polymers contained different amounts of ethyleneoxy units. Two different polymer families were synthesized and compared in this work. The critical difference in the two polymer series is that one contained pendant groups with aromatic rings, in addition to the oligioethyleneoxy moieties, while the other has no aromatic rings in its structure. Polymers with Ph group-containing pendant groups exhibited poor water permeability if they possessed fewer than six ethyleneoxy units. Polymers with more than six ethyleneoxy units inserted between the Ph ring (tail) and the polymeric backbone exhibited reasonable water permeability. Two addnl. series of polymers with mixed pendant groups were synthesized and the water passing properties of the phosphazenes varied in proportion to the hydrophilic to hydrophobic balance induced by each individual pendant group. A final study of polymers with shorter pendant groups demonstrated the effect of pendant group on water permeability. These studies suggest that the polyphosphazenes may be tailored for specific water passing applications. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4COA of Formula: C10H22O3).

Catalytic level identification of ZSM-5 on biomass pyrolysis and aromatic hydrocarbon formation was written by Chen, Wei-Hsin;Cheng, Ching-Lin;Lee, Kuan-Ting;Lam, Su Shiung;Ong, Hwai Chyuan;Ok, Yong Sik;Saeidi, Samrand;Sharma, Amit K.;Hsieh, Tzu-Hsien.

Zeolite socony mobil-5 (ZSM-5) is a common catalyst used for biomass pyrolysis. Nevertheless, the quant. information on the catalytic behavior of ZSM-5 on biomass pyrolysis is absent so far. This study focuses on the catalytic pyrolysis phenomena and mechanisms of biomass wastes using ZSM-5 via thermogravimetric analyzer and pyrolysis-gas chromatog./mass spectrometry, with particular emphasis on catalytic level identification and aromatic hydrocarbons (AHs) formation. Two biomass wastes of sawdust and sorghum distillery residue (SDR) are investigated, while four biomass-to-catalyst ratios are considered. The anal. suggests that biomass waste pyrolysis processes can be divided into three zones, proceeding from a heat-transfer dominant zone (zone 1) to catalysis dominant zones (zones 2 and 3). The indicators of the intensity of difference (IOD), catalytic effective area, catalytic index (CI), and aromatic enhancement index are conducted to measure the catalytic effect of ZSM-5 on biomass waste pyrolysis and AHs formation. The maximum IOD occurs in zone 2, showing the highest intensity of the catalytic effect. The CI values of the two biomass wastes increase with increasing the biomass-to-catalyst ratio. However, there exists a threshold for sawdust pyrolysis, indicating a limit for the catalytic effect on sawdust. The higher the catalyst addition, the higher the AHs proportion in the vapor stream. When the biomass-to-catalyst ratio is 1/10, AHs formation is intensified significantly, especially for sawdust. Overall, the indexes conducted in the present study can provide useful measures to identify the catalytic pyrolysis dynamics and levels. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Synthetic Route of C9H12O3).

The impact of olive oil compounds on the metabolic reprogramming of cutaneous melanoma cell models was written by Brito, Cheila;Tomas, Ana;Silva, Sandra;Bronze, Maria Rosario;Serra, Ana Teresa;Pojo, Marta. And the article was included in Molecules in 2021.Synthetic Route of C9H12O3 The following contents are mentioned in the article:

Cutaneous melanoma is the deadliest type of skin cancer, characterized by a high mol. and metabolic heterogeneity which contributes to therapy resistance. Despite advances in treatment, more efficient therapies are needed. Olive oil compounds have been described as having anti-cancer properties. Here, we clarified the cytotoxic potential of oleic acid, homovanillyl alc., and hydroxytyrosol on melanoma cells. Metabolic viability was determined 48 h post treatment of A375 and MNT1 cells. Metabolic gene expression was assessed by qRT-PCR and Mitogen-Activated Protein Kinase (MAPK) activation by Western blot. Hydroxytyrosol treatment (100 and 200μM) significantly reduced A375 cell viability (p = 0.0249; p < 0.0001) which, based on the expression anal. performed, is more compatible with a predominant glycolytic profile and c-Jun N-terminal kinase (JNK) activation. By contrast, hydroxytyrosol had no effect on MNT1 cell viability, which demonstrates an enhanced oxidative metabolism and extracellular signal-regulated kinase (ERK) activation. This compound triggered cell detoxification and the use of alternative energy sources in A375 cells, inhibiting JNK and ERK pathways. Despite oleic acid and homovanillyl alc. demonstrating no effect on melanoma cell viability, they influenced the MNT1 glycolytic rate and A375 detoxification mechanisms, resp. Both compounds suppressed ERK activation in MNT1 cells. The distinct cell responses to olive oil compounds depend on the metabolic and mol. mechanisms preferentially activated. Hydroxytyrosol may have a cytotoxic potential in melanoma cells with predominant glycolytic metabolism and JNK activation.

Even though Saccharomyces cerevisiae starter cultures are still largely used nowadays, the non-Saccharomyces contribution is re-evaluated, showing pos. enol. characteristics. Among them, Lachancea thermotolerans is one of the key yeast species that are desired for their contribution to wine sensory characteristics. The main goal of this work was to explore the impact of L. thermotolerans com. yeast strain used in sequential inoculation with S. cerevisiae com. yeast on the main enol. parameters and volatile aroma profile of Trnjak, BabiC, Blatina, and Frankovka red wines and compare it with wines produced by the use of S. cerevisiae com. yeast strain. In all sequential fermented wines, lactic acid concentrations were significantly higher, ranging from 0.20 mg/L in Trnjak up to 0.92 mg/L in Frankovka wines, while reducing alc. levels from 0.1% volume/volume in Trnjak up to 0.9% volume/volume in Frankovka wines. Among volatile compounds, a significant increase of Et lactate and iso-Bu acetate, geraniol, and geranyl acetate was detected in all wines made by use of L. thermotolerans. In BabiC wines, the strongest influence of sequential fermentation was connected with higher total terpenes and total ester concentrations, while Trnjak sequentially fermented wines stood up with higher total aldehyde, volatile phenol, and total lactone concentrations Control wines, regardless of variety, stood up with higher concentrations of total higher alcs., especially isoamyl alc. The present work contributed to a better understanding of the fermentation possibilities of selected non-Saccharomyces strains in the overall red wine quality modeling.

Solid-inclusion compounds of ethylene glycol Bu ether (C₄E₁), di(ethylene glycol) Bu ether (C₄E₂) and di(ethylene glycol) hexyl ether (C₆E₂) in β-cyclodextrin (βCD), with general formula represented by the notation {βCD·C_nE_m}, were prepared from aqueous solution and characterized by powder X-ray diffraction (PXRD), thermogravimetric anal. (TGA), FT-Raman and ¹³C CP MAS NMR spectroscopies, at ambient humidity, as true hydrated microcrystalline inclusion compounds, pointing to a cage structure for {βCD·C₄E₁} and a channel structure for both {βCD·C₄E₂} and {βCD·C₆E₂}. In addition, the inclusion compounds were investigated at several defined relative humidities (RHs). Several relative intensities of βCD Raman bands generally ascribed to C-O stretching and CH₂ bending vibrations are found to be influenced by the presence of guests in the βCD cavity or the increase of ambient humidity, or by both of these factors. PXRD patterns show that crystalline structures are preserved for RHs equal or above 20%. Interestingly, important changes on the multiplicity of resonances and in the dispersions of ¹³C CP MAS NMR chem. shifts values for all the carbon atoms of the βCD macrocycle are observed in passing from RH 15% to 20%, suggesting amorphous structures below RH 20%. Overall, the above findings converge to stress the structural relevance of hydration water in the βCD inclusion compounds, either with a cage packing arrangement or with a channel structure.

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. 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.

Validation of a gas chromatography-mass spectrometry isotope dilution method for the determination of 2-butoxyethanol and other common glycol ethers in consumer products was written by Tokarczyk, Ryszard;Jiang, Ying;Poole, Gary;Turle, Richard. And the article was included in Journal of Chromatography A in 2010.Application In Synthesis of 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

A gas chromatog.-mass spectrometry isotope dilution (GC-MS ID) method was developed and tested for the determination of 14 common glycol ethers in consumer products. Stable isotope labeled standards, 2-methoxyethanol-D₇ and 2-butoxyethanol-¹³C₂ (CDN isotopes) were employed to enhance the accuracy and precision of the glycol ethers determination A 1000-fold sample dilution with methanol was applied to avoid column overload and contamination. At this dilution matrix effects were in most cases negligible and did not interfere with the anal. The instrument detection limit (IDL) for analyzed compounds varied from 0.01 to 1 μg/mL; while the estimated limit of quantification (LoQ) varied between different glycol ethers from 0.02 to 3.4 μg/mL. Calibration was tested at 0.1-200 μg/mL and showed that the linear fit is upheld from 0.1 to 10 μg/mL, and extends beyond this range for some of the analytes. Recoveries of glycol ethers from products with different matrixes were similar. The recoveries varied from 87% to 116% between the analyzed compounds, while measurements precision varied between 2% and 14%. The method is applicable to products with glycol ether concentrations >0.002-0.2% (weight/weight). The concentration range can be extended below the specified limits by decreasing the dilution factor; however, with lower dilution the sample matrix effect is expected to be stronger. Products with very high concentrations of glycol ether (>20%) may need to be further diluted prior to injection to avoid column overload. The method can be used for testing liquid and aerosol products designed for household use, such as cleaners, paints, solvents and paint strippers, for compliance and enforcement of regulations which limit glycol ethers content. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Application In Synthesis of 2-(2-(Hexyloxy)ethoxy)ethanol).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) 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. 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.Application In Synthesis of 2-(2-(Hexyloxy)ethoxy)ethanol
