Excess Volumes of Binary Mixtures of Benzene + 1-Alkanols at 303.15 K

Abstract

Excess molar volumes V E of binary mixtures of benzene+ I-propanol, + I-butanol, + 1-pentanol, + 1-hexanol, + 1-heptanol, + I-octanol, + I-nonanol and I-decanol were measured at 303.15 K. The Y E values are positive over the entire range of composition for these mixtures. The results are discussed in terms of intermolecular interactions.

Densities and Excess Molar Volumes of the Butan-1-ol + Cyclohexane + Benzene Ternary System within the Temperature Range (293.15–333.15) K and under Ambient Pressure

“…Figures S1 and S2 depict the relative percent deviation (RPD) of literature values from our measurements for the binary systems containing butan-1-ol to represent the comparability between literature density data and our experimental findings. Notably, binary density data demonstrate a reasonable concordance with values found in the literature. ,− Most of the published density data agree reasonably well with the current values and fall within the percent uncertainty of this work, U r (ρ) = 0.04, as depicted in Figures S1 and S2. Any discrepancies observed between experimental densities and those reported in the literature can be attributed to differences in experimental methods, equipment, conditions, sample purity, and sample preparation procedures.…”

“…In the case of the butan-1-ol (1) + benzene ( 3) system, the literature data obtained via vibrating tube densimetry using Anton-Paar DMA5000 39 show good concordance with our results across the entire composition range, while the data V m E obtained using single-arm pycnometry 15 are in mutual agreement for x 1 > 0.3. The V m E data determined by vibrating tube densimetry, using Anton-Paar DMA58, 41 as well as Kyoto DA300, 38 and those measured dilatometrically 40 significantly differ from our values. The observed discrepancies between current results and the literature can be attributed to differences in experimental methods, equipment, conditions, sample purity, and sample preparation procedures.…”

“…The binary cyclohexane + benzene system was compared with the literature in a recent publication by the authors Figures S7 and S8 in the Supporting Information compare our V m E values to those available in the published literature for the binary butan-1-ol (1) + cyclohexane (2) − , and butan-1-ol (1) + benzene (3) ,− systems, respectively.…”
