Alkyl di-/tri-/tetraoxyethyl β-D-xylopyranosides as derivatives of alkyl xylosides are a class of non-ionic sugar-based surfactants. They were stereoselectively synthesized by the Helferich method. Their properties including hydrophilic-lipophilic balance number, water solubility, surface property, foam property, emulsifying property, and thermotropic liquid crystal property were mainly investigated. The results showed that their water solubility decreased with increasing the alkyl chain length and increasing the number of the oligooxyethyl fragment. The critical micelle concentration had a monotonous decreasing trend with increasing the alkyl chain length. Nonyl di-/tri-/tetraoxyethyl β-D-xylopyranosides [-(OCH₂CH₂)_m-, where m = 2, 3, and 4] exhibited the most excellent foaming ability and foam stability. In the n-octane/water system, dodecyl tetraoxyethyl β-D-xylopyranosides and tetradecyl tetraoxyethyl β-D-xylopyranosides had the strongest emulsion ability. In addition, some alkyl di-/tri-/tetraoxyethyl β-D-xylopyranosides had thermotropic liquid crystal properties. Such sugar-based surfactants, alkyl di-/tri-/tetraoxyethyl β-D-xylopyranosides, will be expected to develop for a variety of practical application.

AXJ-M was written by An, Xuejiao;Zhong, Bin;Chen, Guotao;An, Weijuan;Xia, Xiang;Li, Hanguang;Lai, Fenju;Zhang, Qinghua. And the article was included in Journal of Hazardous Materials in 2021.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

There is a great need for efficiently treating papermaking black liquor because it can seriously pollute both soil and water ecosystems. In this study, the Plackett-Burman (PB) exptl. design combined with response surface methodol. (RSM) was used for improving the biodegradation efficiency of lignin by a new isolated thermophilic and alkali-tolerant strain Serratia sp. AXJ-M, and the results showed that a biodegradation efficiency of 70.5% was achieved under optimal culture conditions. The bacterium with ligninolytic activities significantly decreased target the parameters (color 80%, lignin 60%, phenol 95%, BOD 80% and COD 80%). The control and treated samples were analyzed by gas chromatog.-mass spectrometer (GC-MS), which showed that the concentrations of a majority of low-mol.-weight compounds were decreased after biol. treatment. Furthermore, toxicol., genotoxicity and phytotoxicity studies have supported the detoxification by the bacterium of black liquor. Finally, the genome sequence of the thermophilic, alkali-tolerant and lignin-degrading bacterium AXJ-M was completed, and the genetic basis of the thermophilic and alkali-resistant properties of AXJ-M was preliminarily revealed. The dyp-type peroxidase was first reported to have the potential to catalyze lignin degradation structurally. These findings suggest that Serratia sp. AXJ-M may be potentially useful for bioremediation applications for papermaking black liquor.

Reductive Catalytic Depolymerization of Semi-industrial Wood-Based Lignin was written by Lu, Xiaojia;Lagerquist, Lucas;Eranen, Kari;Hemming, Jarl;Eklund, Patrik;Estel, Lionel;Leveneur, Sebastien;Grenman, Henrik. And the article was included in Industrial & Engineering Chemistry Research in 2021.Recommanded Product: 2380-78-1 The following contents are mentioned in the article:

The current work studies the reductive catalytic depolymerization (RCD) of lignin from a novel semi-industrial process. The aim was to obtain aromatic mono-, di-, tri-, and tetramers for further valorization. The substrate and products were characterized by multiple anal. methods, including high pressure size-exclusion chromatog. (HPSEC), gas chromatog.-mass spectrometry, GC-flame ionization detector (FID), GC-FID/thermal conductivity detector (TCD), and NMR. The RCD was studied by exploring the influence of different parameters, such as lignin solubility, reaction time, hydrogen pressure, reaction temperature, pH, type and loading of the catalyst, as well as type and composition of the organic/aqueous solvent. The results show that an elevated temperature, a redox catalyst, and a hydrogen atm. are essential for the depolymerization and stability of the products, while the reaction medium also plays an important role. The highest obtained mono- to tetramers yield was 98% and mono- to dimers yield over 85% in the liquid phase products. The reaction mechanisms influenced the structure of the aliphatic chain in the monomers, but left the phenolic structure along with the methoxy groups largely unaltered. The current work contributes to the development and debottlenecking of the novel and sustainable overall process, which utilizes efficiently all the fractions of wood, in line with the principles of green engineering and chem.

And the article was included in Journal of Analytical Toxicology in 2019.HPLC of Formula: 2380-78-1 The following contents are mentioned in the article:

The aim of this studywas to provide the exact structure of abundant and unique metabolites of cyclopropylfentanyl along with synthesis routes. In this study, metabolites were identified in 13 post-mortem urine samples using liquid chromatog- raphy quadrupole time-of-flight mass spectrometry (LC-QTOF-MS). Samples were analyzed with and without enzymic hydrolysis, and seven potential metabolites were synthesized inhouse to provide the identity of major metabolites. Cyclopropylfentanyl was detected in all samples, and the most abundant metabolite was norcyclo- propylfentanyl (M1) that was detected in 12 out of 13 samples. Reference materials were synthesized (synthesis routes provided) to identify the exact structure of the major metabolites 4-hydroxyphenethyl cyclopropylfentanyl (M8), 3,4-dihydroxyphenethyl cyclopropylfentanyl (M5) and 4-hydroxy-3-methoxyphenethyl cyclopropylfentanyl (M9). These metabolites are suitable urinary markers of cyclopropylfentanyl intake as they are unique and detected in a majority of hydrolyzed urine samples. Minor metabolites included two quinone metabolites (M6 and M7), not previously reported for fentanyl analogs. Interestingly, with the exception of norcyclopropylfentanyl (M1), the metabolites appeared to be between 40% and 90% conjugated in urine. In total, 11 metabolites of cyclo- propylfentanyl were identified, including most metabolites previously reported after hepatocyte incubation.

Morphologies of three-phase emulsions of the ternary nonionic amphiphile/oil/water systems and their determination by electrical method was written by Lee, Jong-Moon;Shin, Hong-Ju;Lim, Kyung-Hee. And the article was included in Journal of Colloid and Interface Science in 2003.Electric Literature of C10H22O3 The following contents are mentioned in the article:

Equations were developed for the elec. and thermal conductivities of dispersions of 2 different phases of low conductivity in a 3rd, conductive phase. These equations predict the conductivity of the dispersion from the volume fractions and conductivities of the constituent phases. Elec. conductivity measurements on dispersions of 3 liquid phases, i.e., 3-phase emulsions, were made over a wide range of volume fractions of each dispersed phase and used to test the equations. The equations predict accurately dispersion conductivities from the measured volume fractions and conductivities of the constituent phases without any adjustable parameters. The predicted values are in excellent agreement with the measured conductivities of 3-phase emulsions in the nonionic amphiphile/oil/H₂O systems. This leads to the determination of 3-phase emulsion morphologies. When the ratio K_d of the emulsion-drop conductivity to the continuous phase conductivity is O(10^-1)<K_d<1, the elec. method yields the correct morphol. When K_d≪1, the equations predicted several morphologies, but the correct morphol. can be chosen when the data are supplemented by another method such as microscopy. The elec. method, which is a combination of conductivity measurements and their fits to the equations, was proven to be effective and reliable in determination of 3-phase dispersion morphologies. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Electric Literature of C10H22O3).

TOC removal of diethylene glycol mono-n-hexyl ether synthetic wastewater and 1,4-butanediol diglycidyl ether synthetic wastewater with H₂O₂/UV in a batch reactor was written by Hou, Wei-Jie;Tsuneda, Satoshi;Hirata, Akira. And the article was included in Journal of Chemical Engineering of Japan in 2001.Category: ethers-buliding-blocks The following contents are mentioned in the article:

Removal of diethylene glycol mono-n-hexyl ether (DGME) or 1,4-butanediol diglycidyl ether (BDE) from wastewater by H₂O₂/UV was studied. Experiments were carried out in a batch reactor with a low pressure UV lamp (500 W) irradiating UV at 254 nm and at 185 nm (5% of energy). Complete TOC removals were obtained. TOC removals were pseudo-1st-order processes. The removal rates of TOC were governed by the concentration of H₂O₂ added initially and the maximum pseudo-1st-order rate constant and the optimum initial H₂O₂ concentration existed both in the wastewater. The relation between the initial TOC concentration and the optimum initial H₂O₂ concentration exhibited linear in both wastewaters. The optimum initial H₂O₂ concentration in the TOC removal of the BDE wastewater is higher than that of the DGME wastewater at a given initial TOC concentration The maximum pseudo-1st-order rate constant increases with the decrease in the initial TOC concentration in both wastewaters. The maximum pseudo-1st-order rate constant for the DGME wastewater is higher than that for the BDE wastewater at a given initial TOC concentration The exptl. results agree well with the theor. consideration which has been previously proposed by authors when H₂O₂ and TOC concentrations in the wastewater were very high. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Category: ethers-buliding-blocks).

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.

Solid State Inclusion of the Nonionic Surfactant C₁₂E₄ in β-Cyclodextrin, at Various Humidities: A Combined Raman and ¹³C CP MAS NMR Study was written by Cunha-Silva, Luis;Teixeira-Dias, Jose J. C.. And the article was included in Journal of Physical Chemistry B in 2002.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

The inclusion of the nonionic surfactant α-n-dodecyl-ω-hydroxytetra(oxyethylene), C₁₂E₄, in β-cyclodextrin (β-CD), was prepared in the solid state and its structure characterized by powder x-ray diffraction, thermogravimetry, and Raman and ¹³C CP/MAS NMR spectroscopies. Stepwise dehydration was observed in the thermogram, indicating the presence of energetically distinct water mols. Comparison of the dispersions of ¹³C chem. shift values for C1 and C4 atoms of the β-CD macrocycle, within a series of inclusion compounds of C_nE_m homologues, reveals a rather complete symmetrization of the β-CD macrocycle, and the dispersions of ¹³C shifts for C6 atoms point to the particular sensitivity of these atoms to hydrogen-bonding type of interactions. The integrated intensity of the O-H Raman stretching band for the β-CD inclusion compound of C₁₂E₄ is approx. constant for humidities between 20% and 80%. In passing from 15% to 20% of humidity, one observes abrupt relative intensity variations of some Raman bands, in particular at 926 cm^-1, and the sudden decrease of the dispersions of ¹³C chem. shift values for all carbon atoms of the β-CD macrocycle. Overall, the above findings converge to stress the structural relevance of hydration water in the β-CD inclusion compound of C₁₂E₄.

Reuse of biochar residues after lignin degradation will not only save costs but also reduce the pollution, protect and improve the environment. In this study, biochar residue (BR) after peanut shell lignin selective depolymerization on ZSM-5 were recycled, and characterized by SEM, surface area and pore size distribution analyzers, TGA. Subsequently, a series of hybrid matrix membranes were prepared using Et cellulose as the matrix and biochar residue after depolymerization under different reaction conditions as the filler.separation performance of BR/EC membranes for CO₂/CH₄ mixed gas and CO₂/N₂ mixed gas was measured. The results showed that the gas separation membranes prepared with biochar residue (3 h, 300°C) as filler had good gas separation characteristics. The resulting mixed-matrix membrane exhibited a permeability of 66.00 Barrer for CO₂ and selectivities of 9.97 for CO₂/CH₄. Meanwhile, the resulting mixed-matrix membrane exhibited a permeability of 79.53 Barrer for CO₂ and selectivities of 20.01 for CO₂/N₂. Both exceed the upper limit of known pure EC membranes. Therefore, the use of biochar residue after ZSM-5 depolymerization as a filler for gas separation membranes is a feasible way. Furthermore, the membrane is well stabilized, proving its good potential for industrial applications.

The incidence of lung cancer has increased while the mortality rate has continued to remain high. Effective treatment of this disease is the key to survival. Therefore, this study is a necessity in continuing research into new effective treatments. In this study we determined the effects of three different Thai herbs on lung cancer. Bridelia ovata, Croton oblongifolius, and Erythrophleum succirubrum were extracted by Et acetate and 50% ethanol. The cytotoxicity was tested with A549 lung cancer cell line. We found four effective extracts that exhibited toxic effects on A549 cells. These extracts included Et acetate extracts of B. ovata (BEA), C. oblongifolius (CEA), and E. succirubrum (EEA), and an ethanolic extract of E. succirubrum (EE). Moreover, these effective extracts were tested in combination with chemotherapeutic drugs. An effective synergism of these treatments was found specifically through a combination of BEA with methotrexate, EE with methotrexate, and EE with etoposide. Apoptotic cell death was induced in A549 cells by these effective extracts via the mitochondria-mediated pathway. Addnl., we established primary lung cancer and normal epithelial cells from lung tissue of lung cancer patients. The cytotoxicity results showed that EE had significant potential to be used for lung cancer treatment. In conclusion, the four effective extracts possessed anticancer effects on lung cancer. The most effective extract was found to be E. succirubrum (EE).

Catalytic depolymerization of alkaline lignin to value-added phenolic-based compounds over Ni/CeO₂-ZrO₂ catalyst synthesized with a one-step chemical reduction of Ni species using NaBH₄ as the reducing agent was written by Totong, Sansanee;Daorattanachai, Pornlada;Laosiripojana, Navadol;Idem, Raphael. And the article was included in Fuel Processing Technology in 2020.Recommanded Product: 2380-78-1 The following contents are mentioned in the article:

Alk. lignin obtained from paper manufacturing is a potential feedstock for upgrading to produce value-added chems. This study demonstrates the efficiencies of synthesized Ni supported CeO₂-ZrO₂ catalysts to convert this low-cost alk. lignin into value-added phenolic-based chems. for further com. applications. Lignin depolymerization was performed under mild reaction conditions, namely, reaction temperature of 200-300°C, and reaction time of 1-5 h. Three different catalyst preparation methods (simple wet-impregnation, wet-impregnation assisted reduction in H₂ atmosphere and one-step chem. reduction) were investigated and used to evaluate possible correlations between the active Ni phase and catalytic performance in lignin depolymerization The active Ni phase was successfully formed by one-step chem. reduction method which showed a significant improvement on product yield, especially lignin oil. The best result obtained in lignin depolymerization was by using 10%Ni/CeO₂-ZrO₂-red catalyst which resulted in producing a high yield of lignin oil (46.8%) from lignin feedstock under mild condition of 250°C. The major phenolic compounds in lignin oil were: guaiacol, methyl-guaiacol, ethyl-guaiacol, vanillin, acetovanillone, and homovanillic acid. Furthermore, the reaction temperature affected the product yield and product distribution resulting in higher diversity of phenolic compounds in lignin oil.

Polyesters are important plastics, with monomers linked by ester moieties. 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.Recommanded Product: 2380-78-1
