Nagababu, P. published the artcileInvestigation of molecular interactions in binary mixtures of homologous series of aliphatic alcohols with 2-methoxyaniline at various temperatures, Recommanded Product: n-Octanol, the main research area is methoxyaniline binary mixture aliphatic alc mol interaction.

Thermodn. and transport properties (excess molar volume, excess isentropic compressibility and deviation in viscosity) are calculated from the exptl. d., speed of sound and viscosity. The results are analyzed in terms of rupture of hydrogen-bonded chain as the dipolar interaction between 2-methoxyaniline and 1-alkanol (1-hexanol, 1-heptanol and 1-octanol) exceeds the intermol. interaction through dipole-dipole and hydrogen bonding between these unlike mols. The VE results are analyzed in the light of Prigogine-Flory-Patterson theory. Anal. of each of the three contributions viz. interactional, free volume and P* to VE has shown that interactional contribution are pos. for all systems, the free volume effect and P* contribution are neg. for all the mixtures

Almasi, Mohammad published the artcileStudy of interactions in binary mixtures containing normal alkanols; KB integrals and structure factor, Recommanded Product: n-Octanol, the main research area is binary mixture normal alkanol Kirkwood Buff integral structure factor.

In this paper, the investigation on the structure and mol. interactions in the binary systems containing aniline and 1-alkanol (1-pentanol up to 1-decanol) was performed in the framework of Kirkwood-Buff (KB) integrals and exptl. techniques. The interpretation of obtained parameters shows that in binary mixtures with shorter chain alcs., unlike mols. tend to form strong interactions, while increasing in the carbon atom of 1-alkanols reduces the strength of bonds and tendency of the heterogeneous mols. to stay along side. Mixtures structure was studied using the concentration-concentration structure factor, . Results from the application of this parameter show that the heterocoordination occurs in solutions involving 1-pentanol up to 1-heptanol, while for mixtures containing 1-octanol to 1-decanol, homocoordination is predominant. Also, the chem. short-range order parameter, α’which is an important function to understand the complex formation and phase segregation in the liquid mixtures was obtained and discussed for mentioned mixtures

Almasi, Mohammad published the artcileCohesive energy density and internal pressure of benzene and 1-alkanol binary mixtures, Recommanded Product: n-Octanol, the main research area is benzene alkanol binary mixture cohesive energy density internal pressure.

The internal pressure (Pint), cohesive energy d. (ced), and free volume (vf) for liquid mixtures of benzene with (C6 to C10) 1-alkanol are calculated at 303.15 K and atm. pressure. Flory’s statistical theory was employed to drive the internal pressure of five binary mixtures The conductor-like screening model for real solutions (COSMO-RS), in combination with exptl. densities was applied to calculate the cohesive energy d. of the binary systems. The ‘structuredness’ of the fluids above was studied using the Pint/ced ratio. The values are between 0.7 and 1.2, as is the case for non-associated mol. liquids, and demonstrates the non-chem. dispersions and repulsion types for binary liquids The variations of these parameters with mole fraction and length of alkyl chain in the studied 1-alkanol were explained from the perspective of intermol. interactions. It is observed that increase in the Me groups of alc. creates addnl. steric hindrances, loosens the structural packing, and reduces the order of interactions in these mixtures Also, exptl. densities and viscosities at various temperatures were reported for liquid mixtures to verify the existing interactions among unlike mols.

Berthon, Laurence published the artcileHow Phase Modifiers Disrupt Third-phase Formation in Solvent Extraction Solutions, Recommanded Product: n-Octanol, the main research area is solvent extraction neodymium mol dynamics.

The structure of complex organic solutions based on N,N,N,N-tetraoctyldiglycolamide (TODGA) used in actinide separation processes were characterized after water and neodymium extraction The organic phases were characterized using FTIR spectroscopy, ESI-MS spectrometry, Small and Wide Angle X-ray Scattering (SWAXS) and mol. dynamic simulations. The role of the “”phase modifier”” like 1-octanol (used in the innovative SANEX process) or the “”co-extractant”” like DMDOHEMA (used, for example, in the EURO-GANEX process) added to the organic phase to avoid third-phase formation was investigated at mol. and supramol. scales. Without metallic cations in 0.2 mol/L TODGA solution in n-heptane, TODGA mols. are organized in monomers and small aggregates containing mainly two or three TODGA mols. After Nd(NO3)3 extraction, complexes or aggregates are formed in which each neodymium cation is surrounded in average by 2 to 4 TODGA, 3 nitrate ions and 1 to 2 water mols. Polymetallic species (aggregates) may also be formed. Adding 5%Vol 1-octanol or 0.5 mol/L DMDOHEMA to 0.2 mol/L TODGA solution in n-heptane leads to the formation of mixed aggregates containing TODGA and octanol mols. or TODGA and DMDOHEMA mols. These mols. both interact directly with the extracted metallic cation in the organic phase, modifying the structure of the neodymium species, and improving their solubility in this organic phase. At least one TODGA mol. remains in the cation first coordination sphere in both cases and preserves its significant role in the complexation/selectivity of the cations. But it is clear that both 1-octanol and DMDOHEMA have a role in the speciation of the cations in the organic phase: 1-octanol replaces water mols. in the first coordination sphere of Nd, acting as a co-surfactant; DMDOHEMA drives the organization and DMDOHEMA mols. partially replace TODGA in the first coordination sphere of Nd.

Ghosh, Pranab published the artcilePerformance evaluation of polymeric blend of vinyl acetate and acrylate-based copolymers in lubricating oil, Application of n-Octanol, the main research area is polymeric blend vinyl acetate acrylate lubricating oil.

Polymer modification processes like blending has attracted much attention as an easy, cost-effective and less time-consuming method for developing new polymeric materials enriched with versatile com. application. Polymer blends are supposed to carry better thermal and mech. properties compared to their parent polymers. In this view we have prepared a polymer blend of two copolymers- one of vinyl acetate and octyl acrylate and another of Me methacrylate and dodecyl acrylate and characterized them by FT-IR and NMR spectroscopy. The mol. weight was determined by Gel Permeation Chromatog. (GPC). We represented here a comparative study of their mech. property as well as their performance as flow improver.

Worawit, Chanatda published the artcileCombining graphite with hollow-fiber liquid-phase microextraction for extraction of polar organic compounds, Quality Control of 111-87-5, the main research area is graphite hollow fiber liquid phase microextraction extraction polar; organic compound water sample analysis; Carbon nanosorbent; Gas chromatography; Graphite; Hollow-fiber liquid-phase microextraction; Nanomaterial; Trihalomethane.

In this study, we have developed a simple and effective hybrid extraction method based on the incorporation of raw carbon nanosorbents and octanol in the pores of a hollow-fiber membrane for improving the extraction efficiency of relatively polar organic compounds Trihalomethanes (THMs) were used as model analytes. Three types of carbon nanosorbents (graphite, graphene, and multi-walled carbon nanotubes) were studied. The carbon sorbent incorporating membrane was used in a two-phase mode liquid-phase microextraction, with 1-octanol as the acceptor solution Using a graphite-reinforced hollow-fiber membrane and an extraction time of 10 min, enrichment factors of 40-71 were obtained for trichloromethane, bromodichloromethane, bromoform, and chlorodibromomethane. Linear working ranges of 0.2-100μg L-1 and limits of detection ranging from 0.01μg L-1 (for CHCl2Br and CHClBr2) to 0.1μg L-1 (for CHCl3) were achieved. The min. detectable concentrations were far below the maximum concentration levels (60-200μg L-1) set by the WHO for drinking water. The carbon-sorbent-reinforced hollow-fiber liquid-phase microextraction afforded higher extraction efficiency and shorter extraction time compared with conventional hollow-fiber liquid-phase microextraction Finally, the method was applied to the anal. of real water samples, such as drinking water, tap water, and swimming pool water samples.

Corey, Elizabeth A. published the artcileInhibitory signaling in mammalian olfactory transduction potentially mediated by Gαo, Computed Properties of 111-87-5, the main research area is mammalian olfactory receptor neuron inhibition modulation transduction; Combinatorial coding; Inhibition; Modulation; Olfaction; Olfactory receptor neurons.

Olfactory GPCRs in mammalian olfactory receptor neurons mediate excitation through the Gαs family member Gαolf. Here we tentatively associate a second G protein, Gαo, with inhibitory signaling in mammalian olfactory transduction by first showing that odor evoked phosphoinositide 3-kinase-dependent inhibition of signal transduction is absent in the native ORNs of mice carrying a conditional OMP-Cre based knockout of Gαo. We then identify an OR from native rat ORNs that are activated by octanol through cyclic nucleotide signaling and inhibited by citral in a PI3K-dependent manner. We show that the OR activates cyclic nucleotide signaling and PI3K signaling in a manner that reflects its functionality in native ORNs. Our findings lay the groundwork to explore the interesting possibility that ORs can interact with two different G proteins in a functionally identified, ligand-dependent manner to mediate opponent signaling in mature mammalian ORNs.

Wang, Chao published the artcileRobust hydrogen production via pickering interfacial catalytic photoreforming of n-octanol-water biphasic system, COA of Formula: C8H18O, the main research area is hydrogen production octanol water pickering interfacial catalysis; Pt/TiO2 nanosheets; hydrogen production; microfluidics; photoreforming; pickering interfacial catalysis.

Pickerin g emu lsion offers a promis ing platform for conductin g interfa cial reaction s bet ween immis cible reagents ; it is part icularly suit able for hy drogen producti on by photo reforming of non-w ater soluble biomass liq uid and w ater. Here in, Pt-p romoted (001)-fa cet-domi nated anatase TiO2 nanosheets were synthesized by a hydrothermal route associated with microfluidic technol. for high activity and metal dispersion, and selective surface modification was carried out for preparing Janus particles. Photoreforming hydrogen production through n-octanol and water that formed O/W microemulsion with an average diameter of 540μm was achieved to obtain amphiphilic catalyst. The as-prepared 2D Janus-type catalysts exhibited remarkably stable emulsification performance as well as photocatalytic activity. This finding indicates that triethoxyfluorosilane had negligible impact on the catalytic performance, yet provided a remarkable benefit to large sp. surface area at microemulsion interface, thereby enhancing the H2 yield up to 2003μmol/g. The cyclic experiments indicate that the decrease in cyclic performance was more likely to be caused by the coalescence of the microemulsion rather than the decrease in catalytic activity, and the microemulsion could be easily recovered by simply hand shaking to more than 96% of the initial performance.

Lopez, Kenneth published the artcileMultiple linear regression models for predicting the n-octanol/water partition coefficients in the SAMPL7 blind challenge, HPLC of Formula: 111-87-5, the main research area is octanol water sulfonamide partition coefficient; Empirical methods; Multiple linear regression; N-sulfonamides; SAMPL7 blind challenge; n-Octanol/water partition coefficients.

A multiple linear regression model called MLR-3 is used for predicting the exptl. n-octanol/water partition coefficient (log PN) of 22 N-sulfonamides proposed by the organizers of the SAMPL7 blind challenge. The MLR-3 method was trained with 82 mols. including drug-like sulfonamides and small organic mols., which resembled the main functional groups present in the challenge dataset. Our model, submitted as “”TFE-MLR””, presented a root-mean-square error of 0.58 and mean absolute error of 0.41 in log P units, accomplishing the highest accuracy, among empirical methods and also in all submissions based on the ranked ones. Overall, the results support the appropriateness of multiple linear regression approach MLR-3 for computing the n-octanol/water partition coefficient in sulfonamide-bearing compounds In this context, the outstanding performance of empirical methodologies, where 75% of the ranked submissions achieved root-mean-square errors < 1 log P units, support the suitability of these strategies for obtaining accurate and fast predictions of physicochem. properties as partition coefficient of bioorganic compounds Journal of Computer-Aided Molecular Design published new progress about Molecules. 111-87-5 belongs to class alcohols-buliding-blocks, name is n-Octanol, and the molecular formula is C8H18O, HPLC of Formula: 111-87-5.
