Phase Behavior of Microemulsions Made with n-Alkyl Monoglucosides and n-Alkyl Polyglycol Ethers was written by Ryan, Larry D.;Schubert, Kai-V.;Kaler, Eric W.. And the article was included in Langmuir in 1997.COA of Formula: C10H22O3 The following contents are mentioned in the article:

The phase behavior of mixtures of water, octane, n-alkyl polyglycol ethers (C_iE_j), and n-alkyl β-D-glucopyranosides (C_mG₁) is systematically studied as a function of temperature and composition The addition of C_mG₁ to water-octane-C_iE_j mixtures promotes formation of a three-phase region that is nearly independent of temperature in all mixtures studied. The size and extent of this three-phase region are shown as a function of C_mG₁ concentration and hydrophobicity and C_iE_j amphiphilicity. This unique behavior arises from the extremely low oil solubility of the alkyl monoglucosides. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4COA of Formula: C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) 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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid.

Thiols Act as Methyl Traps in the Biocatalytic Demethylation of Guaiacol Derivatives was written by Pompei, Simona;Grimm, Christopher;Schiller, Christine;Schober, Lukas;Kroutil, Wolfgang. And the article was included in Angewandte Chemie, International Edition in 2021.Product Details of 2380-78-1 The following contents are mentioned in the article:

Demethylating Me Ph ethers is challenging, especially when the products are catechol derivatives prone to follow-up reactions. For biocatalytic demethylation, monooxygenases have previously been described requiring mol. oxygen which may cause oxidative side reactions. Here we show that such compounds can be demethylated anaerobically by using cobalamin-dependent methyltransferases exploiting thiols like Et 3-mercaptopropionate as a Me trap. Using just two equivalent of this reagent, a broad spectrum of substituted guaiacol derivatives were demethylated, with conversions mostly above 90%. This strategy was used to prepare the highly valuable antioxidant hydroxytyrosol on a one-gram scale in 97% isolated yield. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Product Details of 2380-78-1).

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. 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.Product Details of 2380-78-1

Small-angle neutron scattering studies of aqueous solutions of short-chain amphiphiles was written by D’Arrigo, G.;Giordano, R.;Teixeira, J.. And the article was included in European Physical Journal E: Soft Matter in 2003.Product Details of 112-59-4 The following contents are mentioned in the article:

The authors present small angle neutron scattering measurements on binary aqueous solutions of some short-chain amphiphiles (diols, triols, glycols and diglycols) at room temperature The spectra were analyzed in terms of the Teubner-Strey phenomenol. formula which allows to obtain a measure for the amphiphilicity strength of each system (amphiphilicity factor f_a). In some systems, however, other models, valid for micellar solutions, give also a good representation of the spectra. As a result, independently of the type of hydrophilic group side (oxydrilic or oxirane), these systems cover the entire accessible amphiphilicity scale (-1 < f_a < 1). Some disordered systems (f_a > 1) presumably are able to form micelle-like aggregates. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Product Details of 112-59-4).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) 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.Product Details of 112-59-4

And the article was included in Separation Science and Technology in 2018.Recommanded Product: 112-59-4 The following contents are mentioned in the article:

In this work, a facile method for determination of foaming properties of frothers was used. It was based on measuring the foam height in a flotation machine at different concentrations of frothers. Based on the foam height-concentration curve, a new foaming parameter, so-called concentration at half of the maximum foam height CMH, was proposed. Assessment and usefulness of CMH were shown in flotation of quartz. The concentration of amine at the critical contact angle CCA, at which amine starts to be a collector, was also determined The determined values of CCA were similar to CMH and were equal to 1.3, 0.14 and 0.03 mM for ButNH₂, HexNH₂ and OctNH₂, resp. The values of CMH and CCA depended on the alkyl chain of frothers.

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
