Density and Viscosity Measurements of Dimethoxymethane and 1,2-Dimethoxyethane from 243 K to 373 K up to 20 MPa

“…These data are in agreement with the correlation, Table 2) and other authors, ρ (exptl), from the correlation of the present results given by Eq. 11, ρ (calcd), as a function of density, ( ) this work, ( ) Aizawa and Kato [21], ( ) Barthel et al [22], ( ) Burgdorf et al [23], (♦) Comelli et al [17], ( ) Conesa et al [24], ( ) Deng et al [25], ( Á ) George and Sastry [26], (+) Douheret et al [27], (×) Ku and Tu [28], ( ) Manfredini et al [29], ( • ) Muhuri and Hazra [30], ( ) Ohji and Tamura [31], ( ) Pal and Sharma [32], ( ) Roy et al [33], ( ) Tamura and Yamasawa [34], ( ) Tovar et al [35], ( ) Wallace and Mathews [36], and ( ) Zhao et al [37] with an average absolute deviation of 0.09 % in density.

Densities and derived thermodynamic properties of (2-methoxyethanol+1-propanol, or 2-propanol, or 1,2-propandiol) at temperatures from T=(293.15 to 343.15)K

“…The stated purities of the solvents by the manufacturer were further ascertained by comparing their density with the corresponding literature values [9][10][11][12][13][14][15] and they are in good agreement. Purity grades and density of the pure components are listed in table 1.…”

“…This behaviour may be explained by the relative energetically favourable rotameric conformers[10,25] (anti and gauche). The observed V E m values suggest a stronger interaction in the system 2-methoxyethanol with 2-propanol than in that containing 1-propanol.…”

Effect of placement of hydroxyl groups in isomeric butanediol on the behaviour of thermophysical and spectroscopic properties of pyrrolidin-2-one

“…In the present study, this holds true except for (PY + 1,4-BTD) for which V E shows S-shaped behaviour. The D a G * E values may also be considered a reliable measure to detect the presence of interactions between molecules [6,26,27]. The variation of D a G * E for PY and BTD is shown graphically in figure 7 and is negative for all the mixtures except for (PY + 1,4-BTD) for which it shows S-shaped behaviour and its negative value for different PY and BTD mixtures increases in the order: 1,4-BTD < 1,2-BTD < 1,3-BTD < 2,3-BTD.…”
