“…From the plot in Fig. 3, it is observed that the present measurements agree with our previous results [5] very well over the temperature range from 263.07 K to 383.16 K, with a maximum deviation of −1.59 %. But at temperatures from 243.14 K to 258.12 K, larger deviations of −4.31 % to −10.06 % were observed.…”

“…Francesconi and Comelli [19] reported measurements at 288.15 K and 298.15 K, with deviations of −0.39 % and −0.73 % from the correlation. For the purpose of comparison with our previous work [5], obtained with the vibrating-tube densimeter, the small extrapolations of the present data to the saturation line were performed, and the vapor pressures were from Pan et al [8]. The differences vary from −0.60 % at 233.16 K to 0.95 % at 363.11 K. The viscosity deviations for dimethoxymethane between this work and literature results are shown in Fig.…”

“…Five viscosity data were found from the literature of [20], and the deviations from the correlation were within 3 % except for the result of Timmermans [20] at 303.15 K, which amounts to −9.65 %. Comparisons of the present data and our previous work [5] were made with extrapolations of the viscosity correlation to the saturation line. From the plot in Fig.…”

Measurements of the density and viscosity of dimethoxymethane and 1,2-dimethoxyethane are reported over the temperature range from 243 K to 373 K and at pressures up to 20 MPa. The measurements were performed simultaneously using a vibrating-wire instrument operated in the forced mode of oscillation. The overall uncertainties of these results are 2.0 % in viscosity and 0.2 % in density. The measurements were correlated with a Tait-type equation for density and a hard-sphere model for viscosity. The maximum absolute deviation and the average absolute deviation (AAD) of the density measurements from the correlation for dimethoxymethane are 0.065 % and 0.012 %, respectively, and for 1,2-dimethoxyethane, are 0.16 % and 0.044 %. With regard to viscosity, the maximum absolute deviation and the AAD of the present results from the correlation for dimethoxymethane are 1.55 % and 0.40 %, respectively, and for 1,2-dimethoxyethane, are 1.05 % and 0.26 %. Comparisons of the experimental data and measurements from the literature with values calculated by the correlations at different temperatures and pressures are presented.

Molecular Interaction Study of Binary Mixtures of THF with Methanol and o-Cresol - an Optical and Ultrasonic Study

et al. 2009

The refractive indices, densities and ultrasonic velocities of binary liquid mixtures of tetrahydrofuran (THF) with methanol and o-cresol over the entire composition range have been measured at 293, 303 and 313 K. Refractive index, density and ultrasonic velocity data have been used to evaluate the molar refraction deviation ∆R m , deviation in ultrasonic velocity ∆u, excess internal pressure π These results suggest that specific strong interactions are taking place in THF + o-cresol mixture while dispersive forces seem to be responsible for behaviour of THF + methanol mixture. Further, experimental refractive index and density data of these mixtures were also used to test the validity of the empirical/semi-empirical relations and models for refractive index and density, respectively.

A hierarchical method to integrated solvent and process design of physical CO₂ absorption using the SAFT‐γ Mie approach

et al. 2015

in Wiley Online Library (wileyonlinelibrary.com) Molecular-level decisions are increasingly recognized as an integral part of process design. Finding the optimal process performance requires the integrated optimization of process and solvent chemical structure, leading to a challenging mixed-integer nonlinear programming (MINLP) problem. The formulation of such problems when using a group contribution version of the statistical associating fluid theory, SAFT-c Mie, to predict the physical properties of the relevant mixtures reliably over process conditions is presented. To solve the challenging MINLP, a novel hierarchical methodology for integrated process and solvent design (hierarchical optimization) is presented. Reduced models of the process units are developed and used to generate a set of initial guesses for the MINLP solution. The methodology is applied to the design of a physical absorption process to separate carbon dioxide from methane, using a broad selection of ethers as the molecular design space. The solvents with best process performance are found to be poly(oxymethylene)dimethylethers.
