X-ray study of oil-microemulsion and oil-water interfaces in ternary amphiphilic systems was written by Mitrinovic, Dragoslav M.;Williams, Scott M.;Schlossman, Mark L.. And the article was included in Physical Review E: Statistical, Nonlinear, and Soft Matter Physics in 2001.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

X-ray reflectivity and diffuse scattering measurements are presented from the interfaces between oil-rich and microemulsion bulk phases and between oil-rich and water-rich phases in three-component microemulsion systems (consisting of water, alkane, and C_iE_j, where the last represents n-alkyl polyglycol ether with i = 4,6,10 and j = 1,2,4). The x-ray measurements are analyzed with a two-parameter fit that determines the interfacial roughness, varying from 25-160 Å, and the interfacial tension, varying from 1.4-0.03 mN/m, for these samples. Although a nonmonotonic profile at the oil-microemulsion interface is not observed, these measurements exclude the presence of oscillating profiles with repeat distances >500 Å. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Synthetic Route of C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) 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. 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.Synthetic Route of C10H22O3

Study of the reactive excited-state dynamics of delipidated bacteriorhodopsin upon surfactant treatments was written by Cheng, Chi-Wen;Lee, Yuan-Pern;Chu, Li-Kang. And the article was included in Chemical Physics Letters in 2012.Related Products of 112-59-4 The following contents are mentioned in the article:

The dynamics of the reactive excited-state of bacteriorhodopsin treated with various surfactants have been investigated through the measurement of pump-probe absorption spectra. Upon excitation of bR at 570 nm in the presence of ionic surfactants CTAB and SDS, the lifetime of the reactive excited-state of the all-trans protonated Schiff base, probed at 460 nm, was observed to increase up to 20%, whereas an insignificant change was observed upon addition of neutral surfactant C6E2. Measurements of steady-state absorption spectra, fluorescence, and CD indicated that the bR suspensions retain their trimeric configuration with partial delipidation. This removal of lipids causes a structural alteration and the varied excited-state dynamics. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Related Products of 112-59-4).

Microwave-assisted extraction of hydroxytyrosol from alperujo and its impact on the stability of mayonnaise was written by Rigane, Ghayth;Ben Salem, Ridha. And the article was included in Journal of the Indian Chemical Society in 2020.Related Products of 2380-78-1 The following contents are mentioned in the article:

Extraction is one of the crucial steps for research and development of plant secondary metabolites. Microwave power and extraction time were selected as extraction parameters of hydroxytyrosol from alperujo. To achieve this goal, the optimization of phys. parameters was carried out by analyzing the obtained extracts using GC-MS apparatus Optimum conditions of microwave-assisted extraction based on maximum levels of responses were medium microwave power with 15 min of alperujo treatment. Maximum levels of hydroxytyrosol were obtained under these conditions (~1.9 g of hydroxytyrosol/kg of alperujo). Furthermore, we have studied the stability of mayonnaise after addition of hydroxytyrosol extract ranging between 65 and195μg by following the changes on free acidity, peroxide value, conjugated dienes as well as content of polyphenols and squalene. This study was conducted for 4 wk and the mayonnaise samples were stored protected from light at room temperature These results showed that 195μg of hydroxytyrosol rich extract may be of great benefit to improve the stability of the mayonnaise against oxidation 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 are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.Related Products of 2380-78-1

Experimental investigation of rice straw oxidative pyrolysis process in a hot-rod reactor was written by Zhao, Shanhui;Zhang, Yunliang;Su, Yi. And the article was included in Journal of Analytical and Applied Pyrolysis in 2019.Related Products of 2380-78-1 The following contents are mentioned in the article:

In order to improve the utilization of rice straw resources, oxidative pyrolysis of rice straw was investigated in this work. The effects of temperature and oxygen concentration on rice straw oxidative pyrolysis were taken into consideration. Results show that more permanent gases and water were produced under oxidative atmospheres, while the yield of char and tar decreased. The main gaseous products were CO and CO₂ due to the heterogenous oxidation of rice straw/char or secondary reaction of nascent volatiles. Gas chromatograph coupled with a mass spectrometer results show that the oxidative pyrolysis promoted the conversion of primary tar to generate secondary and tertiary tar via in-situ exothermic reaction and active radical attack. Pore structure anal. results of bio-char samples show that oxidative treatment benefited the formation of micro pores and inhibited bio-char thermal annealing at high temperature In general, the oxidative treatment promoted the pyrolysis process and benefited the char modification via in-situ oxidation and formation surface active structure and porosity. 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. 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.Related Products of 2380-78-1

Wetting transitions at the air-liquid interface of water+tetradecane+C₆E₂ mixtures was written by Yeh, Ming-Chih;Chen, Li-Jen. And the article was included in Journal of Chemical Physics in 2001.Application In Synthesis of 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

In this study, the interfacial phenomena and the wetting behaviors of the ternary system water+tetradecane+diethylene glycol monohexyl ether (C₆E₂) were carefully examined at 20°C. There is one three-liquid-phase-coexisting tie triangle and three two-liquid-phase-coexisting envelopes in the triangle phase diagram of the system water+tetradecane+C₆E₂ at 20°C. In the two-liquid-phase-coexisting region on the water/C₆E₂ side, the upper C₆E₂-rich liquid phase exhibits a sequence of transition: nonwetting partial wetting complete wetting at the lower aqueous phase/air interface by simply varying the system composition Similarly, in another two-liquid-phase-coexisting region on the tetradecane/C₆E₂ side, the upper tetradecane-rich liquid phase also demonstrates a sequence of transition at the lower C₆E₂-rich phase/air interface. Some of these wetting transitions can be deduced by the critical wetting theory of Cahn, while the other transitions seem to have no obvious relevance to a critical end point.

Quantitative Dietary Fingerprinting (QDF)-A Novel Tool for Comprehensive Dietary Assessment Based on Urinary Nutrimetabolomics was written by Gonzalez-Dominguez, Raul;Urpi-Sarda, Mireia;Jauregui, Olga;Needs, Paul W.;Kroon, Paul A.;Andres-Lacueva, Cristina. And the article was included in Journal of Agricultural and Food Chemistry in 2020.Application of 2380-78-1 The following contents are mentioned in the article:

Accurate dietary assessment is a challenge in nutritional research, needing powerful and robust tools for reliable measurement of food intake biomarkers. In this work, we have developed a novel quant. dietary fingerprinting (QDF) approach, which enables for the first time the simultaneous quantitation of about 350 urinary food-derived metabolites, including (poly)phenolic aglycons, phase II metabolites, and microbial-transformed compounds, as well as other compounds (e.g., glucosinolates, amino acid derivatives, methylxanthines, alkaloids, and markers of alc. and tobacco consumption). This method was fully validated for 220 metabolites, yielding good linearity, high sensitivity and precision, accurate recovery rates, and negligible matrix effects. Furthermore, 127 addnl. phase II metabolites were also included in this method after identification in urines collected from acute dietary interventions with various foods. Thus, this metabolomic approach represents one-step further toward precision nutrition and the objective of improving the accurateness and comprehensiveness in the assessment of dietary patterns and lifestyles.

Spontaneous formation of monodisperse vesicles near the cloud point of an aqueous amphiphilic system was written by Murthy, K.;Easwar, N.;Singer, E.. And the article was included in Colloid and Polymer Science in 1998.SDS of cas: 112-59-4 The following contents are mentioned in the article:

Monodisperse vesicular structures were produced spontaneously from an almost structure-less aqueous amphiphilic system: water/di(ethylene glycol) mono-hexyl ether (C₆E₂)/sodium cholate. Individually, neither C₆E₂ nor the bile acid produces noticeable aggregate structures in an aqueous solution However, the presence of small amounts of bile acid in the C₆E₂/water binary system produced large microstructures, besides pushing the miscibility gap to higher temperatures Dynamic light scattering studies indicate the presence of very monodisperse structures of sizes ranging from 15-50 nm in radii. The radii of these structures show strong dependence on the concentrations of the components and on the distance in temperature from the cloud point. For a given set of conditions the sizes are very stable and reproducible. Electron microscopy and conductivity measurements confirm these structures as vesicles. These may be formed due to the association of bile acid with C₆E₂ producing the geometrical parameters necessary for the formation of vesicles. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4SDS of cas: 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.

Hydrothermal Liquefaction of Lignocellulosic Biomass Using Potassium Fluoride-Doped Alumina was written by Alper, Koray;Tekin, Kubilay;Karagoz, Selhan. And the article was included in Energy & Fuels in 2019.Related Products of 2380-78-1 The following contents are mentioned in the article:

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).

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.

In search of an efficient frother for pre-flotation of carbonaceous shale from the Kupferschiefer stratiform copper ore was written by Kowalczuk, Przemyslaw B.;Buluc, Batuhan;Sahbaz, Oktay;Drzymala, Jan. And the article was included in Physicochemical Problems of Mineral Processing in 2014.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

Frothers such as aliphatic alcs. (C_nH_2n+1OH), poly(propylene glycols) (HO(C₃H₆O)_mH), poly(propylene glycol) alkyl ethers (C_nH_2n+1O(C₃H₆O)_mH) and poly(ethylene glycol) alkyl ethers (C_nH_2n+1O(C₂H₄O)_mH), can be used for collectorless flotation of a sample of carbonaceous Cu shale manually separated from the Kupferschiefer stratiform Cu ore. Flotation is influenced by the type and dose of frothers. The best flotation results were obtained with tri(propylene glycol) Bu ether C₄P₃, tri(propylene glycol) Pr ether C₃P₃ and tri(propylene glycol) P₃. For these frothers, the yield vs. frother dose relationship was in the form of convex curves indicating that carbonaceous Cu shale can float at relatively low dosages of the frother. These frothers can be used for pre-flotation of carbonaceous matter from the investigated Cu ore. Other frothers formed concave yield-frother dose relationships and were less effective. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Synthetic Route of C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Synthetic Route of C10H22O3
