This work reports physical property measurements of binary mixtures of butylbenzene with n-decane, n-dodecane, n-tetradecane, n-hexadecane, or n-heptadecane. Densities and viscosities were measured at temperatures from (293.15 to 373.15) K, and speeds of sound were measured at temperatures from (293.15 to 333.15) K, except for those of n-heptadecane, which were measured starting at 303.15 K. Densities increased with increasing mole fraction of butylbenzene. Excess molar volumes were positive and increased with increasing alkane chain length, except for those of heptadecane which were similar to those of n-hexadecane. Analysis of excess molar volumes using the Prigogine–Flory–Patterson model showed that the interaction term contributed more to excess molar volume than the free volume or P* term. As the mole fraction of butylbenzene increased, speeds of sound increased for n-decane and n-dodecane mixtures but decreased for other alkane mixtures to values below those of both pure components before increasing again. Viscosities decreased as the mole fraction of butylbenzene increased except for those of some n-decane mixtures, which were below those of butylbenzene and n-decane. Viscosity mole fraction data were fit using the three-body McAllister model. Bulk moduli and surface tension increased with increasing mole fraction of butylbenzene, and flash points fell between those of the individual components. These mixtures can be used as surrogates for petroleum-based fuels.

Improving the Interpretation of Small Molecule Diffusion Coefficients

Diffusion-ordered NMR spectroscopy (DOSY) is increasingly widely used for the analysis of mixtures by NMR spectroscopy, dispersing the signals of different species according to their diffusion coefficients. DOSY is used primarily to distinguish between the signals of different species, with the interpretation of the diffusion coefficients observed usually being purely qualitative, for example to deduce whether one species is bigger or smaller than another. In principle, the actual values of diffusion coefficient obtained carry important information about the sizes of different species and on interactions between species, but the relationship between diffusion coefficient and molecular mass is in general a very complex one. Here a recently proposed analytical relationship between diffusion coefficient and molecular mass for the restricted case of small organic molecules is tested against a wide range of data from the scientific literature and generalized to cover a range of solvents and temperatures.

“…The positive values of excess molar volume indicate the van der Waals-type interactions that are categorized as dispersion forces. The decreasing excess molar volume with temperature is attributed to packing effect [39,40]. Therefore, one can say that these interactions may be dominated in the nanofluid investigated within different concentration ranges.…”
