Hydrophobic polydimethylsiloxane (PDMS) membranes in pervaporation are used to remove ethanol compounds from aqueous solutions as fermentation broths. Conventional PDMS membranes, which have been extensively studied, have high fluxes but relatively low selectivities. A new technique to modified ...

1-Dodecanol has good extraction efficiency of cresols from aqueous solution. The liquid-liquid equilibrium (LLE) data of ternary system 1-dodecanol-(o-/m-/p-)-cresol-water were determined at 298.15 K, 313.15 K, 323.15 K, 333.15 K and 343.15 K under atmospheric pressure. The Hand and Othmer-Tobia...

Glycol is a chemical compound that is diol containing two hydroxyl groups. In a clinical setting, most commonly encountered glycol is ethylene glycol. Other less frequently encountered glycols include diethylene glycol, propylene glycol, ethylene glycol monobutyl ether (EGBE), and ethylene glyco...

Permeabilities of carbon dioxide through glycol derivative supported liquid membranes were measured at 30–70 °C by a sweep gas method. The species of glycol derivative used in this work are glycerol, monoethylene glycol, diethylene glycol, triethylene glycol, diethylene glycol monomethyl ether...

Diethylene glycol dimethyl ether (diEGdiME) and triethylene glycol dimethyl ether (triEGdiME), widely used organic solvents, are structurally related to several compounds that produce reproductive and developmental toxicity, including teratogenicity in laboratory animals. In the present studies,...

Triethylene glycol dimethyl ether (triEGdiME) is structurally related to several compounds which produce reproductive and developmental toxicity, including teratogenicity in laboratory animals. In the present study, triEGdiME (0, 250, 500, or 1000 mg/kg/day) was administered by gavage to timed-p...

Measurements of Raman spectra of triethylene glycol dimethyl ether and its cation complexes were carried out. It was found by analyses of the spectra and normal vibration calculations that triethylene glycol dimethyl ether shows remarkable conformational adaptation corresponding to various natur...

Ozonation of pure aqueous solutions of the polar aliphatic refractory triethylene glycol dimethyl ether (TEGDME) which is a typical representative of organic solutes of oil reclaiming wastewaters does not lead to effective mineralization unless high ozone doses are applied. Small doses of UV irr...

Densities (ρ) and viscosities (η) for water (W) + triethylene glycol (TrEG), W + tetraethylene glycol (TeEG), and W + tetraethylene glycol dimethyl ether (TeEGDME) were measured for the whole range of composition at five different temperatures ranging from 303.15 K to 323.15 K. Surface tension...

A computer-operated static apparatus has been used for the measurement of the bubble pressures of the (1,1,1,2-tetrafluoroethane + triethylene glycol dimethyl ether) system at temperatures between (283 and 323) K in the composition range where the first component is prevailing, i.e., mainly for ...

Ethylene glycol is one of the most usually used liquid media for realization of different industrial processes. In present work thermochemistry of solvation of inert gases and organic solutes in ethylene glycol was thoroughly studied using solution calorimetry technique. Enthalpies of solution o...

Methacryloyl-terminated poly[methyl(3,3,3-trifluoropropyl)siloxane] (PMTFPS-MA) macro-monomers with controlled segment length were designed and synthesized by anionic ring-opening polymerization of 1,3,5-trimethyl-1,3,5-tri(3′,3′,3′-trifluoropropyl)cyclotrisiloxane (F3). Then, a series of nov...

BackgroundGlycol ethers (GEs) are oxygenated solvents widely found in occupational and consumer water-based products. Some of them are well-known reproductive and developmental toxicants.

In this article, we use defect engineering approach to fine-tune the pore size of MOF-808-SO4. A series of defective MOF-808-SO4 with different pore size were prepared by varying the amount of isophthalic acid as the defective ligand during the synthesis. We obtained a linear correlation between...

High-content screening data derived from physiologically-relevant in vitro models promise to improve confidence in data-integrative groupings for read-across in human health safety assessments. The biological data-based read-across concept is especially applicable to bioactive chemicals with def...

By using molecular dynamics in canonical ensemble (constant atom number, volume and temperature (NVT)) the adsorption of Sebacic Acid (SA) and 1,10-Decanediol (DD) respectively onto the surfaces of an iron-oxide nanoparticle is simulated. The nanoparticle is built by taking into account the inve...

A thermochemical study of 1,10-decanediol has been performed using adiabatic calorimetry and thermoanalytical techniques. The low-temperature heat capacities of 1,10-decanediol were determined precisely with a small sample automated adiabatic calorimeter in the temperature range from 80 to 370 K...

PVA acetalization by 10-undecenal was carried out in aqueous medium in order to obtain PVA with acetalization degree (AD) ranging from 0.36 up to 1.85 mol%. PVA chain organization in 8 wt% aqueous solutions was investigated through Small Angle X-ray Scattering measurements. The significant modif...

Although there were approximate 10 million potential yields of coal-tar pitch (CTP) annually in China since 2011, plenty of environmental pollutants of polycyclic aromatic hydrocarbons (PAHs) existing in CTP limit its many applications. Reducing the content of PAHs hazardous to environment in CT...

A comparative study of the oxidation of undecanal by chromic acid in micellar and isotropic media is reported. In the former solutions this oxidation is quite negligible, while in the latter it takes place as indicated by the reduction of Cr(VI). This difference in reactivity has been taken as e...
