On microemulsion phase behavior and the monomeric solubility of surfactant was written by Burauer, Stefan;Sachert, Thomas;Sottmann, Thomas;Strey, Reinhard. And the article was included in Physical Chemistry Chemical Physics in 1999.Related Products of 112-59-4 The following contents are mentioned in the article:

The authors highlight the advantageous features of both short- and long-chain surfactant systems in determining the most important properties of 3-phase bodies and genuine microemulsions. To this end 1st the phase behavior of the simple system H₂O-n-dodecane-C₄E₁ (Bu monoglycol ether) is discussed. From temperature-concentration sections through the phase prism at various H₂O-to-oil ratios, a number of isothermal Gibbs triangles are constructed, which can quant. be compared with theories. Also, the critical tie-lines of the 3-phase body were precisely determined From these measurements it is evident that there is a nonnegligible monomeric solubility of the surfactant in the excess phases. For long-chain surfactant systems, the more efficient the surfactant, the larger is the size of the microstructure of the microemulsion. The authors report a striking correlation between the efficiency of a surfactant and its monomeric solubility in the excess phases for 23 systems H₂O-n-alkane-C_iE_j. Probably the monomeric solubility of the surfactant in oil and H₂O might be the key to describing the main features of these microemulsion systems. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Related Products of 112-59-4).

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.

Molecular modeling of the standard state heat of formation was written by Bagheri, Mehdi;Yerramsetty, Krishna;Gasem, Khaled A. M.;Neely, Brian J.. And the article was included in Energy Conversion and Management in 2013.Application In Synthesis of 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

The standard heat of formation is a basic thermophys. property required in determining enthalpies of reaction and in thermodn. stability analyses. Further, the enthalpies of formation are important in investigating bond energies, resonance energies and the nature of chem. bonds. Therefore, the development of accurate structure-based estimation methods for large varieties of chem. species is greatly beneficial in enhancing capability in process and product development. In this work, quant. structure-property relationship (QSPR) models were developed for a structurally diverse DIPPR dataset of standard heats of formation comprising 1765 pure compounds involving 82 chem. classes. We have employed both linear and nonlinear QSPR modeling techniques. The linear approach involves the use of constricted binary particle swarm optimization (BPSO) for feature selection and multiple-linear regression. In the nonlinear approach, the optimum network architecture and its associated inputs are identified using a wrapper-based feature selection algorithm combining differential evolution and artificial neural networks. Model predictions for the root-mean-square error of the BPSO and nonlinear approaches were 138 and 97 kJ/mol, resp. 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 are also usually derived from carboxylic acids.

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.Application In Synthesis of 2-(2-(Hexyloxy)ethoxy)ethanol

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).

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. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Formula: C9H12O3

Synthesis, Structure, and Ionic Conductivity of Self-Assembled Amphiphilic Poly(methacrylate) Comb Polymers was written by Liu, Gao;Reinhout, Melanie;Mainguy, Brian;Baker, Gregory L.. And the article was included in Macromolecules in 2006.Category: ethers-buliding-blocks The following contents are mentioned in the article:

Methacrylate comb polymers were synthesized that have amphiphilic teeth of ethylene glycol oligomers capped with alkyl groups. Both segments are of exact length to promote self-organization and crystallization The atactic methacrylate backbone plus close proximity to the polymer backbone inhibits crystallization of the oligoethylene oxide segments, but the terminal alkyl segments readily crystallize. Wide-angle X-ray diffraction and differential scanning calorimetry were used to characterize polymer side chain crystallization and its evolution as a function of the length of the amphiphilic teeth. An anal. of the d spacings places the oligoethylene glycol segment and the first eight carbon atoms of the alkyl chain in an amorphous phase. An ∼1 Å/carbon atom increase in the d spacing is consistent with the crystalline segments being tilted relative to the polymer backbone. When the number of carbon atoms in alkyl segments is ≥14, addition of LiClO₄ yields an ionic conducting ethylene oxide phase with retention of the alkyl crystallization These novel polymer electrolytes use crystallization as a structural element to maintain dimensional stability.

Integration of hydrothermal carbonization and aqueous phase reforming for energy recovery from sewage sludge was written by Oliveira, Adriana S.;Sarrion, Andres;Baeza, Jose A.;Diaz, Elena;Calvo, Luisa;Mohedano, Angel F.;Gilarranz, Miguel A.. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.Safety of 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

This study investigates the energy recovery from sewage sludge by combining hydrothermal carbonization and aqueous phase reforming of the generated process water. The hydrothermal treatment was carried out at 170°C and 230°C for 1 h, and produced a hydrochar with adequate physicochem. properties, such as a higher heating value (20-24 MJ kg^-1) than sludge, improved fuel ratio (0.2-0.5) and a broad comprehensive combustion index (5.8 x 10^-7 to 10.0 x 10^-7 min^-2 °C^-3). Aqueous phase reforming of the process water was carried out at 220°C and 25-29 bar for 4 h. A maximum H₂ yield of 98.7 mmol H₂ gTOC^-1 was achieved using a bimetallic Pt/Rh catalyst supported on carbon black and for the process water obtained at the lowest carbonization temperature The integration of hydrothermal carbonization and aqueous phase reforming processes is an interesting alternative for the management and energy recovery of sewage sludge, which allows reaching a potential energy recovery of 17.3 MJ per kg of dry sewage sludge, equivalent to 93.5% gross energy recovery, under optimized conditions.

Limited Secondary Organic Aerosol Production from Acyclic Oxygenated Volatile Chemical Products was written by Humes, Mackenzie B.;Wang, Mingyi;Kim, Sunhye;Machesky, Jo E.;Gentner, Drew R.;Robinson, Allen L.;Donahue, Neil M.;Presto, Albert A.. And the article was included in Environmental Science & Technology in 2022.Formula: C10H22O3 The following contents are mentioned in the article:

Volatile chem. products (VCPs) have recently been identified as potentially important unconventional sources of secondary organic aerosol (SOA), in part due to the mitigation of conventional emissions such as vehicle exhaust. Here, we report measurements of SOA production in an oxidation flow reactor from a series of common VCPs containing oxygenated functional groups and at least one oxygen within the mol. backbone. These include two oxygenated aromatic species (phenoxyethanol and 1-phenoxy-2-propanol), two esters (Bu butyrate and Bu acetate), and four glycol ethers (carbitol, Methyl Carbitol, Butyl Carbitol, and hexyl carbitol). We measured gas- and particle-phase products with a suite of mass spectrometers and particle-sizing instruments. Only the aromatic VCPs produce SOA with substantial yields. For the acyclic VCPs, ether and ester functionality promotes fragmentation and hinders autoxidation, whereas aromatic rings drive SOA formation in spite of the presence of ether groups. Therefore, our results suggest that a potential strategy to reduce urban SOA from VCPs would be to reformulate consumer products to include less oxygenated aromatic compounds This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Formula: C10H22O3).

Effects of Zn-Containing Flux on Sn-3.5Ag Soldering with an Electroless Ni-P/Au Surface Finish: Microstructure and Wettability was written by Sakurai, Hitoshi;Baated, Alongheng;Lee, Kiju;Kim, Seongjun;Kim, Keun-Soo;Kukimoto, Youichi;Kumamoto, Seishi;Suganuma, Katsuaki. And the article was included in Journal of Electronic Materials in 2010.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

The microstructure resulting from Sn-3.5Ag soldering on an electroless Ni-P/Au pad using flux containing Zn(II) stearate was investigated. The content of zinc compound in the flux was 0 weight% (Z-0), 20 weight% (Z-20) or 50 weight% (Z-50). A study of the interfacial microstructure revealed that both Z-20 and Z-50 fluxes yielded a thinner P-rich layer at the interface than did the Z-0 flux. In addition, compared with the bulky Ni-Sn intermetallics of the Z-0 joint interface, refined interfacial intermetallic compounds (IMCs) were observed when using Zn-containing fluxes, Z-20 and Z-50. Based on qual. analyses of both Z-20 and Z-50 joint interfaces, it was presumed that their intermetallic layers would consist of Ni, Zn, and Sn. Addnl., the Ni content in the IMC layer of the Z-50 joint was lower than that of the Z-20 joint. Electron probe microanal. (EPMA) of the initial Z-50 joint interface revealed Zn in the interfacial reaction layer, suggesting that Zn participated in the reaction between solder and the surface finish at an early stage of soldering. Consequently, the supply of Zn from the flux diminished Ni diffusion into the molten solder during heating. This effect may have caused a thin P-rich layer to form at the joint interface.

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).

This ability to participate in hydrogen bonding confers some water-solubility.HPLC of Formula: 2380-78-1

Mutual Solubility and Lower Critical Solution Temperature for Water + Glycol Ether Systems was written by Christensen, Scott P.;Donate, Felipe A.;Frank, Timothy C.;LaTulip, Randy J.;Wilson, Loren C.. And the article was included in Journal of Chemical and Engineering Data in 2005.Quality Control of 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

Mutual solubility and the lower critical solution temperature (LCST) are reported for a number of water + ethylene glycol ether and water + propylene glycol ether systems near atm. pressure. For the systems studied, the LCST is in the range of -10° to 48°. Glycol ethers are unusual organic solvents in that they have both hydrophobic and hydrophilic functionality and can hydrogen bond with water. Because of this, their interactions with water are complex and difficult to predict. The presence of an LCST is characteristic of hydrogen-bonding mixtures, and the value of the LCST reflects the relative magnitude of hydrophobic/hydrophilic interactions in solution A higher LCST value is indicative of a glycol ether with greater hydrophilic character. For water + ethylene glycol ether mixtures, the glycol ether becomes increasingly hydrophilic (LCST increases) as the number of oxyalkylene repeating units increases. The opposite effect is seen for water + propylene glycol ether mixtures In this case, the glycol ether becomes more hydrophobic (LCST decreases) as the number of oxyalkylene repeating units increases. The results clearly demonstrate that water + glycol ether interactions are strong functions of both chem. structure and temperature This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Quality Control of 2-(2-(Hexyloxy)ethoxy)ethanol).

Voltammetric behaviour of drug molecules as a predictor of metabolic liabilities was written by Fuchigami, Hikari;Bal, Mandeep K.;Brownson, Dale A. C.;Banks, Craig E.;Jones, Alan M..

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.
