“…A comparison of the densities and viscosities of n -undecane to the literature data are in Table . Our experimental densities agree with the literature density values − within an absolute average percentage deviation of 0.03, 0.03, 0.05, 0.05, and 0.04% for n -undecane, 1-propanol, 1-butanol, 1-pentanol, and 1-hexanol. Densities for the binary mixtures of n -undecane + 1-propanol, + 1-butanol, + 1-pentanol, and + 1-hexanol have been measured from 283.15 to 363.15 K over the whole composition range and atmospheric pressure.…”

This paper presents densities and viscosities of binary mixtures of n-undecane with 1-propanol, 1-butanol, 1-pentanol, and 1-hexanol from 283.15 to 363.15 K at 0.1 MPa over the entire composition range. Densities come from a vibrating tube densimeter, while viscosities are from a pellet microviscometer. A three-body McAllister equation correlates the kinematic viscosities together with an equation based upon a quadratic mixing rule for the Gibbs energy of activation. The excess molar volumes and viscosity deviations calculated from the experimental data have positive and negative deviations from ideality over the temperature range, respectively.

Vapor Pressure and Its Temperature Dependence of 28 Organic Compounds: Cyclic Amines, Cyclic Ethers, and Cyclic and Open Chain Secondary Alcohols

2016

The vapor pressures p of 28 organic compounds were accurately measured by a static method in the temperatures range (273 to 323) K. These include cyclic amines (CH 2 ) n NH with n = 2−7, N-methylpyrrolidine, N-methylpiperidine, morpholine, N-methylmorpholine, piperazine, N-methylpiperazine, N,N′-dimethylpiperazine), cyclic ethers (tetrahydrofuran, 2-methyltetrahydrofuran, 2,5-dimethyltetrahydrofuran, tetrahydropyran, 1,3-dioxolan, 1,4-dioxan), cyclic and open-chain secondary alcohols (cyclopentanol, cyclohexanol, cycloheptanol, 2-butanol, 3-pentanol, 3-hexanol, 4-heptanol), as well as 2-methoxyethylamine and 3-methoxypropylamine. For six substances, no p data were already available in the literature at any temperature, and for another eight only one paper each was found. The parameters of the Antoine equation were determined to allow interpolation and extrapolation of the experimental results. The enthalpy of vaporization, Δ vap H, at 298.15 was obtained for each compound from the derivative dp/dT. For nine compounds, Δ vap H values had not been determined before. Either p and Δ vap H at 298.15 K for all substances considered were compared with available literature values. For p, the disagreement is less than 1% for 10 substances and (1 to 3) % for another 8 compounds; for Δ vap H, it is less than 1% with respect to 18 literature data, of which 10 are calorimetric. All these confirm the high precision of p measurements here reported.

“…Corresponding values for a of pure C 6 H 14 from Watanabe and Seong are indicated in Figure (left) by the black dashed line. For pure C 6 H 14 O, a was derived from experimental data for the thermal conductivity − and density − as well as isobaric heat capacities obtained from the empirical correlation proposed by Zábranský et al and is represented by a second-order polynomial fit in Figure (right). Considering that the derived a values of pure C 6 H 14 O used for the fit deviate by up to 11% from each other, for both C 6 H 14 and C 6 H 14 O, the pure thermal diffusivity data agree with the present data within combined uncertainties.…”

Diffusivities in Binary Mixtures of n-Hexane or 1-Hexanol with Dissolved CH₄, Ne, Kr, R143a, SF₆, or R236fa Close to Infinite Dilution

This work is a continuation of previous studies focusing on the influence of intermolecular interactions on the diffusive mass transport in mixtures consisting of liquids with dissolved gases by determining the Fick diffusion coefficient of the mixtures or self-diffusion coefficient of the gas solutes. Dynamic light scattering, Raman spectroscopy, and molecular dynamics simulations are applied to study the interplay between the liquid structure and diffusive mass transport in binary mixtures consisting of methane, neon, krypton, sulfur hexafluoride, and the two refrigerants R143a and R236fa dissolved in n-hexane or 1-hexanol. Experiments and simulations were performed at the macroscopic thermodynamic equilibrium close to infinite dilution of the solute at temperatures between 303 and 423 K. The obtained Fick diffusion coefficients increase with increasing temperature and are always smaller in mixtures based on 1-hexanol compared to those of n-hexane. For both solvents, a decreasing molar mass of the solutes leads to increasing Fick diffusion coefficients with the exception of methane and neon showing the opposite behavior. Next to a general discussion and comparison with the literature, the present diffusivity data are compared with values predicted by a semiempirical model, which was previously developed to predict mass diffusivities in binary mixtures consisting of n-alkanes or 1-alcohols with dissolved gases close to infinite dilution.
