Speeds of sound and isentropic compressibilities of (n-alkoxyethanols+ toluene) at T= 298.15 K

Thermodynamic, Ultrasonic, and Transport Study of Binary Mixtures Containing 2-(2-Methoxyethoxy)ethanol and Alcohols at (293.15–323.15) K

“…This was accomplished by utilizing the Karl Fisher coulometer (756KF Coulometer Metrohm). Experimental values of density, speed of sound, and refractive index of the pure liquids are compared in Table at (293.15, 298.15, 303.15, 313.15, and 323.15) K, and these values show good agreement with the published results. ,− …”

“…No further purification was attempted owing to their high-purity grade, which was more than 0.99 mass fraction. 1415.5 12 1.4233 1.01501 9 1417.1 14 1.4243 1.01670 11 1415.98 16 1.0164 17 1.01539 18 1.0154 13 1.01591 19 1.0164 20 1.01487 21 1.0164 12 1.01591 15 1.0164 14 1.01445 16 31 1108 32 1.3264 0.7867 34 1102 28 1.3267 0.7866 23 1102.81 35 1.3275 0.786671 36 1.32645 28 0.78686 37 1.32645 38 0.7863 39 1.3266 0.78666 41 31 1152 32 1.3593 33 0.7858 23 1142 28 1.3593 25 0.785339 36 1.3608 32 0.78540 37 1.35922 28 0.7849 39 1.35922 38 0.78497 41 1.3593 49 0.7850 42 1.3597 1223.22 27 1.3850 25 0.8036 52 1223 28 1.38494 28 0.8033 25 1.385 53 0.8034 28 1.3852 41 1216 32 1.3838 33 0.7995 30 1206 28 1.3832 25 0.800 51 1205.64 35 1.3848 32 0.7996 52 1205.69 56 1.38307 28 0.79961 3...…”

Thermodynamic and optical studies of some ethylene glycol ethers in aqueous solutions at T=298.15K

“…They were partially degassed by passing nitrogen gas just prior to use. The purity of all the compounds was checked by comparing the experimental density (q), speed of sound (u), and refractive index (n D ) data for pure liquids with the literature as listed in table 1 [13][14][15][16][17][18][19]. All the solutions were prepared in freshly prepared doubly distilled water on molality basis by using Mettler balance with the precision of ±0.1 mg.…”

“…The molar refraction of the solution is obtained by the expression [14]. c Reference [15]. d Reference [16].…”

Reply to the letter to the editor by E. Zorebski, S. Ernst about the paper “Densities, speeds of sound and isentropic compressibilities of the ternary mixture 2-propanol + acetone + cyclohexane and the constituent binary mixtures at 298.15 and 313.15K” [Fluid Phase Equilib. 215 (2004) 253–262]

“…In recent years, excess molar volume, V E , and excess isentropic compressibility, κ E s , [3][4][5] and excess molar volume, V E , and the changes of the isentropic compressibilities, ␦κ s , [6][7][8][9][10][11][12][13][14][15][16][17] have been interpreted in terms of strength of interaction between the molecules of the components of a given systems. As we have stated, we consider that other parameter must be calculated.…”
