Thermophysical and optical studies of molecular interactions in binary mixtures of diethyl carbonate with aromatic compounds at temperatures from 298.15 to 323.15 K

Intra- and Inter-molecular Interactions between 1-Alkanol and Benzonitrile: Computational and Thermodynamic Study

“…As well, before the measurement of thermophysical properties all the solvents were used after double distillation and being degassed with a vacuum pump under an inert atmosphere. However, Table displays the comparison of studied experimental properties of pure solvents along with the corresponding literature data ,− at all the studied temperatures and at 0.1 MPa. Moreover, for the sake of comparison the experimental ρ and u of the pure solvents and their mixtures were represented in Figures S1 and S2 together with literature data at 308.15 K showing good agreement with experimental data.…”

“…1−4 Benzonitrile molecules are aprotic, highly polar (μ = 4.01 D at 298.15 K) 5 and possess a nonassociated structure in their liquid state. 6 Furthermore, benzonitrile is mainly used as a solvent or intermediate in various manufacturing industries such as dyes, textiles, perfumes, drugs, rubber, and specialty lacquers. 6,7 Also, it is used as an additive to jet-fuel and drying additive for acrylic fibers.…”

As well, 1-alkanols are used in many chemical and technological processes as a resourceful industrial solvent, and are inexpensive and easily available at high purity.…”

“…Mainly, density and speed of sound are prerequisite for chemical engineering design as well as process optimization. As well, these properties are very useful in elucidating the dipole–dipole interactions, polarity, H-bonds, and structural interactions of mixed solvents. − Benzonitrile molecules are aprotic, highly polar (μ = 4.01 D at 298.15 K) and possess a nonassociated structure in their liquid state …”
