Protic ionic liquids are formed by a Bronsted acid-base neutratization and due to the presence of a proton, which is Abel to promote extensice hydrogen bonding, have different characteristics from imidazolium based ones.
This article presents the analysis of the following physical properties such as refractive indices, excess molar volumes, sound velocity and the temperature dependence of the ternary system ethanol þ n-hexane þ n-octane in the temperature range 288.15–323.15 K at atmospheric pressure. The derived properties are calculated from data obtained experimentally and fitted to Cibulka equation.
This study presents the analysis of different thermodynamic properties (refractive indices, excess molar volumes and ultrasonic velocity) and the temperature dependence of the ternary mixture ethanol + n-hexane + n-nonane at the range 288.15–323.15 K and atmospheric pressure. The derived properties were computed from experimental data and were fitted to the Cibulka equation.
This article reports experimental densities, refractive indices and speeds of sound of the binary mixtures chlorobenzene + (n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-undecane or n-dodecane) and speeds of sound of the ternary
mixtures chlorobenzene + n-hexane + (n-undecane or n-dodecane) at 298.15
K and atmospheric pressure, over the whole concentration range. The corresponding derived properties were computed from the experimental data.
The results were fitted by means of the Redlich–Kister equation for binary mixtures and the Nagata equation for ternary mixtures. A set of estimation methods were applied, and an interpretation in terms of structure and length of molecular chain of the n-alkane
molecules was made
This study presents the analysis of different thermodinamic properties and the temperature dependence of the ternary mixture etanol + n-hexane – n-nonane at the range 299.15-323.15 K and atmospheric pressure.
The measures of the refractive índices of the ternary mixtures chlorobenzene + n-hexane + (n-nonane or n-decane) have done at 298.15 and atmospheric pressure.
This paper contains the results of a new experimental study of the effect of temperature on density, refractive index on mixing and ultrasonic velocity for a number of linear n-alkanes conbined with ethanol. A perusal of deviations between the experimental and calculated derived magnitudes shows that the predictive procedures give a qualitative estimation for the studied mixtures due to their high nonideality.
