Excess molar volumes of (an isomer of butanol + benzene or toluene) at the temperature 308.15 K

Temperature Dependence of Densities and Excess Molar Volumes of the Ternary Mixture (1-Butanol + Chloroform + Benzene) and its Binary Constituents (1-Butanol + Chloroform and 1-Butanol + Benzene)

“…Comparisons of our experimental results of V E for the 1-butanol (1) + benzene (3) system at (293.15, 298.15, 303.15, and 308.15) K with the data reported previously [8][9][10] show that our V E data are in very good agreement (for the maximum V E values, at x 1 = 0.35, the difference is less than 4% for all studied temperatures). Larger disagreements exist only for the case of data reported by Bhardway et al [11] at 308.15 K (nearly 15%). Since the 1-butanol (1) + chloroform (2) system exhibits an S-shape of the V E − x 1 curves, comparisons between the experimental and literature data [7] at 303.15 K were performed in the area of maximum (at x 1 = 0.2) and minimum V E values (at x 1 = 0.8).…”

“…For the binary mixtures the ρ and V E literature data cover the following temperatures: 303.15 K [7] for the 1-butanol (1) + chloroform (2) mixture and 293.15 K [8], 298.15 K [9], 303.15 K [10], and 308.15 K [9,11] for the 1-butanol (1) + benzene (3) mixture. Although literature V E data were reported at several temperatures for the 1-butanol (1) + benzene (3) system, no values of V E have been found for the entire temperature range studied here, especially for the 1-butanol (1) + chloroform (2) mixture.…”

Densities, Viscosities, and Refractive Indices of Binary Mixtures of Benzene with Isomeric Butanols at 30°C

“…Weak hydrogen bonding of aromatic rings with proton donors (like alcohols) appears to play an important role in the structure of certain biomolecules [5,6]. To the best of our knowledge, there has been no study on benzene + isomeric butanol binary mixtures from the point of view of their volumetric, viscometric and refractive index behavior at 30 • C except for the volumetric study of these mixtures by Brown and Smith [7] and Bhardwaj et al [8] at 25 and 30 • C. These considerations led us to undertake the present study.…”

Excess volumes and dielectric properties for (methyl methacrylate + a branched alcohol) atT= 298.15 K andT= 308.15 K

“…Similar observations have been made in interpreting the excess volumes of (branched alcohols + aromatic hydrocarbons). (6,11) (7) and standard deviation s of the difference between the calculated and experimental excess …”

“…The relative size of both the acrylic ester and 1-alcohol molecules determines the predominance of a particular type of interactions over the other. It has been suggested by various investigators (6)(7)(8)(9)(10)(11) that branching in the alkyl group of the alcohol affects both hydrogen bonding as well as the interactions with the added second component.…”
