“…Between 0.2 < x(H 2 O) < 0.8 there are slight deviations (27,39,40,55,58,59) from our values at some temperatures. At T = 298.15 K, which seems to be the most frequently used temperature in the density measurements, there is an excellent agreement between our V E m values and the values reported by Bai et al, (57) de Visser et al, (56) Davis, (54) Chu et al, (40) and Benedetti et al (39) {figure 2(c)}. The dilatometric V E m values reported by Rajasekhar et al (60) at T = 303.15 K {figure 3(a)} and Singh et al (62) at T = 308.15 K {figure 3(b)} differ quite dramatically from the dilatometric values of Pal et al (61) and from the values obtained in this work by the density measurements at the corresponding temperatures.…”

“…The ultrasonic properties in (amide + water) mixtures exhibit a maximum in ultrasonic velocity (table 3) and a minimum in isentropic compressibility (figure 1) and intermolecular free length (table 3) except in the case of FA/W where these properties monotonically change. This behavior indicates significant interactions between amide and [2] 0.998244 [6], [20] 0.94383 [7] 0.936337 [2] 1.10643 [7] 1.02759 [7] 1.12975 [5] 0.99889 [7] 0.943761 [8] 0.93615 [12] 1.10701 [15] 1.0286 [13] 1.12919 [19] 0.99876 [27] 0.942915 [10] 0.9350 [13] 1.107019 [16] 1.028311 [16] 1.12915 [35] 0.998319 [36] 0.94420 [20] 0.9365 [25] 1.0283 [17] 0.9446 [24] 0.935287 [11] 1.02872 [18] 0.99404 [27] 0.943320 [36] 0.943915 [37] a Used in this work.

“…The interest in these solvents arises from a theoretical view as well as from the biological, pharmaceutical and other applications of pure solvents and their aqueous solutions. The volumetric properties of amide aqueous solutions have been extensively studied: formamide [1][2][3][4][5], N-methylformamide [5][6][7], N,N-dimethylformamide [3][4][5][7][8][9][10], N,N-dimethylacetamide [1][2][3][4][11][12][13][14], pyrrolidin-2-one [5,7,15,16], N-methyl-2-pyrrolidinone [5,7,[16][17][18]. The ultrasonic behavior of amides in water [4,9,16,19,20] or other solvent mixtures [21][22][23][24][25] has been also reported as well as their dielectric constants [15,26] and viscosity behavior [4,5,13,…”

“…The data concerning the functions V E = f(x) and H E = f(x) applying to {(1 À x)F + xH 2 O}, {(1 À x)NMF + xH 2 O}, and {(1 À x)DMF + xH 2 O} were calculated from data in [16,17,[30][31][32] and the values of functions at the given composition of the mixture were calculated with the use of the commonly known Redlich-Kister equation.…”
