isobaric vapor liquid equilibrium for binary and ternary systems with toluene 2 Methoxyethanol and dimethyl sulfoxide at 101 3 kpa
Fluid Phase Equilibria, 2014Co-Authors: Shuo Zhao, Peng Bai, Chang SunAbstract:Abstract Isobaric vapor–liquid equilibrium (VLE) data for binary systems of toluene + 2-Methoxyethanol, 2-Methoxyethanol + dimethyl sulfoxide (DMSO) and toluene + DMSO were obtained by using a Fischer VLE 602 equipment at 101.3 kPa, as well as for the ternary system of toluene + 2-Methoxyethanol + DMSO. The binary VLE data were considered to be thermodynamically consistent according to the Wisniak's modification of the Herington test and the Wisniak's L–W test. It was determined that toluene and 2-Methoxyethanol form binary azeotrope at 379.08 K, 70.2 mol% toluene at 101.3 kPa. The binary VLE data were correlated by using Wilson, NRTL and UNIQUAC models with minor deviations. The ternary system was well predicted from binary interaction parameters and passed both the Wisniak–Tamir's modification of McDermott–Ellis test and the Wisniak's L–W test. Besides, the ternary VLE data were also satisfactorily correlated by using Wilson, NRTL and UNIQUAC models. Moreover, the change of phase equilibria behavior of toluene and 2-Methoxyethanol due to the addition of DMSO is significant. Therefore, DMSO is recommended as a promising entrainer for the separation of toluene and 2-Methoxyethanol azeotropic mixture by extractive distillation.

Dielectric properties of 2-Methoxyethanol + isobutylamine, 2-Methoxyethanol + sec-butylamine, and 2-Methoxyethanol + tert-butylamine binary mixtures
Physics and Chemistry of Liquids, 2004Co-Authors: Cezary M. Kinart, Wojciech J. Kinart, Dorota Chęcińska-majak, Aneta ĆwiklińskaAbstract:Relative permittivities of numerous binary mixtures of 2-Methoxyethanol (1) + isobutylamine (2), 2-Methoxyethanol (1) + sec-butylamine (2), and 2-Methoxyethanol (1) + tert-butylamine (2), between 291.15 and 313.15 K, are reported.

The results are fitted to the Redlich–Kister polynomial equation to estimate the binary coefficients and standard errors. Furthermore, the experimental results are used to expose the nature of binary interactions in the bulk of the binary mixtures studied.

Comparison of urinary creatine with other biomarkers for the detection of 2-Methoxyethanol-induced testicular damage.
Biomarkers, 1996Co-Authors: Ruth P. Draper, Dianne M Creasy, John A. TimbrellAbstract:Abstract This study has compared different biomarkers of testicular damage, in particular evaluating urinary creatine as a non-invasive marker. Male rats were exposed to various doses of 2-Methoxyethanol, a known testicular toxicant. Pathological damage, testis weight, urinary creatine and creatinine, serum lactate dehydrogenase, isozyme C4 (LDH-C4), and serum testosterone were determined. 2-Methoxyethanol caused dose-dependent pathological damage to the testes which was detectable at the lowest dose (100 mg kg(-1)). Urinary creatine excretion was significantly raised at all doses but testis weight was only significantly decreased at the highest two doses (500, 750 mg kg(-1)). Serum testosterone was only significantly decreased at 500 mg kg(-1) and LDH-C4 was not significantly increased at any dose. Therefore urinary creatine was the most sensitive marker of 2-methoxethanol-induced testicular damage and dysfunction.

The detection of subchronic testicular damage using urinary creatine: studies with 2-Methoxyethanol.
Archives of toxicology, 1995Co-Authors: Michael Butterworth, Dianne M Creasy, John A. TimbrellAbstract:We have previously shown that a number of testicular toxicants administered acutely to rats raise urinary creatine. The aim of this study was to determine if this creatinuria was maintained during subchronic testicular damage. Repeated exposure of rats to 2-Methoxyethanol for 10 days administered in the drinking water caused significant testicular damage at the highest dose. The urinary creatine: creatinine ratio was significantly increased in the animals receiving the highest dose (220 mg/kg per day) and also those receiving doses of 87 mg/kg per day. Increases in the ratio seen after the lowest dose (43 mg/kg per day) were significant in some cases, but showed more variability. Relative testicular weight was only significantly reduced after the highest dose. Increases in body weight over the time of exposure were only significantly lower after the highest dose of 2-Methoxyethanol. The results indicate that urinary creatine may be a useful biomarker for chronic testicular damage.

isobaric vapor liquid equilibria for the binary systems 1 methoxy 2 propanol 2 Methoxyethanol 2 butanone 2 Methoxyethanol and water 2 Methoxyethanol at pressures of 74 5 101 3 and 134 0 kpa
The Journal of Chemical Thermodynamics, 2015Co-Authors: Arturo Bejarano, Juan C. De La FuenteAbstract:Abstract Isobaric (vapor + liquid) equilibria of three binary systems (1-methoxy-2-propanol + 2-Methoxyethanol), (2-butanone + 2-Methoxyethanol) and (water + 2-Methoxyethanol), was measured using an apparatus with dynamic recirculation and gas chromatography analysis for both phases. The measurements were carried out at pressures of (74.5, 101.3, and 134.0) kPa and temperature ranged from (343 to 407) K. No partial liquid miscibility was observed for any of the systems studied. Azeotropic behavior was verified for the system (water + 2-Methoxyethanol) at the water-rich region. Thermodynamic modeling of the data measured was successfully accomplished for (2-butanone + 2-Methoxyethanol) and (water + 2-Methoxyethanol). In order to represent the no-ideality of the liquid phase, three alternatives for the activity coefficient model were used, Non Random Two Liquid, van Laar and Wilson. Results showed that the relative root mean square deviations from the experimental molar fractions were,

Isobaric Vapor–Liquid Equilibrium for Binary and Ternary Systems of 2-Methoxyethanol, Ethylbenzene, and Dimethyl Sulfoxide at 100.00 kPa
Journal of Chemical & Engineering Data, 2018Co-Authors: Danxia Shen, Tao Chen, Peng Bai, Xianghai GuoAbstract:The isobaric vapor–liquid equilibrium (VLE) data for the binary systems 2-Methoxyethanol + ethylbenzene, ethylbenzene + dimethyl sulfoxide (DMSO), and 2-Methoxyethanol + DMSO and the ternary system 2-Methoxyethanol + ethylbenzene + DMSO were measured with a Fischer VLE 602 apparatus at 100.00 kPa. The VLE data for all the binary and ternary systems were thermodynamically consistent and passed the Wisniak’s L–W test. The binary VLE data were correlated with the Wilson, nonrandom two-liquid, and universal quasichemical models with minor deviations. The ternary VLE data predicted from the corresponding binary interaction parameters agreed well with the experimental data. The azeotropic temperature and composition of the 2-Methoxyethanol and ethylbenzene azeotropic mixture at 100.00 kPa were 391.05 K and 60.15 mol % 2-Methoxyethanol, respectively. Additionally, the azeotrope disappeared after adding DMSO, which confirms that DMSO can serve as a prospective entrainer for separating 2-Methoxyethanol from ethylb...
