Isothermal Vapor Pressures of Three Binary Systems: n-Tetradecane + Methyl Dodecanoate, Methyl Tetradecanoate, or Methyl Hexadecanoate between 353.15 and 453.15 K
Journal of Chemical & Engineering Data, 2017Co-Authors: Lakhdar Sahraoui, Mokhtar Benziane, Kamel Khimeche, Ilham Mokbel, Jacques JoseAbstract:Isothermal vapor pressures of three binary systems, methyl dodecanoate (1) + n-Tetradecane (2); methyl tetradecanoate (1) + n-Tetradecane (2); and methyl hexadecanoate (1) + n-Tetradecane (2), were measured by means of a static apparatus at temperatures between 353.15 and 453.15 K. The data of the pure components were correlated by the Antoine equation. A maximum azeotropic behavior is observed for the binary mixture, methyl dodecanoate (1) + n-Tetradecane (2). The molar excess Gibbs energies GE were deduced from Barker’s method by fitting the experimental points through Redlich–Kister equation. The NRTL and UNIQUAC models were applied to regress the experimental vapor liquid equilibrium (VLE). The investigated systems were successfully represented by the two models.

isothermal vapor liquid equilibria of n Tetradecane ethyl hexanoate ethyl decanoate and ethyl tetradecanoate
Journal of Chemical & Engineering Data, 2013Co-Authors: Mokhtar Benziane, Amine Dahmani, Kamel Khimeche, Ilham Mokbel, Jacques JoseAbstract:The vapor pressures of three binary systems, (ethyl hexanoate (1) + n-Tetradecane (2)), (ethyl decanoate (1) + n-Tetradecane (2)), and (ethyl tetradecanoate (1) + n-Tetradecane (2)), were measured by means of a static apparatus at temperatures between (373.15 and 453.15) K. We correlated the data with the Antoine equation. The molar excess Gibbs energies GE obtained from these data by using Barker’s method were fitted to the Redlich–Kister equation. A maximum azeotropic behavior is observed for the binary mixture {ethyl decanoate (1) + n-Tetradecane (2)}. Positive values of the excess Gibbs energy are obtained for all of the investigated temperatures and compositions. The data were also correlated by using Wilson equation. The predicted GE obtained by using group contribution model, UNIFAC (Gmehling version), are different to the experimental values. These deviations are more important for systems {ethyl decanoate (1) + n-Tetradecane (2)} and {ethyl tetradecanoate (1) + n-Tetradecane (2)}.

numerical simulation for predicting dsc crystallization curves of Tetradecane hexadecane paraffin mixtures
Thermochimica Acta, 2014Co-Authors: M. Mahdaoui, T Kousksou, El T Rhafiki, J.m. Marín, Y ZeraouliAbstract:Abstract In this paper, the crystallization of the binary mixture system of Tetradecane and hexadecane in differential scanning calorimetry (DSC) cell has been studied experimentally and numerically. Different concentrations of Tetradecane–hexadecane paraffin mixture were studied. The finite volume method is utilized to solve the heat transfer problem, and the general source-based enthalpy method is employed to handle the liberation of latent heat due to the solidification process. The enthalpy function of the binary mixture during the crystallization process is presented. The effects of the cooling rate and the initial concentration of Tetradecane on the kinetics of the crystallization process are examined. It is found that the phase change process of the binary mixture takes place over a temperature range and the temperature range depends on the mixture composition.

paraffin wax mixtures as phase change materials
Solar Energy Materials and Solar Cells, 2010Co-Authors: T Kousksou, A Jamil, El T Rhafiki, Y ZeraouliAbstract:Abstract Melting of the binary mixture system of Tetradecane and hexadecane in Differential Scanning Calorimetry (DSC) cell has been investigated experimentally and numerically. Different concentrations of Tetradecane–hexadecane paraffin mixture were studied. It is found that the phase change process of the binary mixture takes place over a temperature range and the temperature range depends on both the heating rate and the mixture composition. The proposed study shows also that for the same concentration of Tetradecane and using various heating rates, we will be able to predict the solidus and liquidus temperature of the binary mixture from DSC curves.

modelization of the release from a Tetradecane water hexadecane multiple emulsion evidence of significant micellar diffusion
Langmuir, 2007Co-Authors: M. Stambouli, I. Pezron, D. Pareau, D. Clausse, Juan Ramon Avendanogomez, J. L. GrossiordAbstract:The release of Tetradecane from a multiple emulsion of the type Tetradecane/water/hexadecane was studied experimentally using the differential scanning calorimetry technique. The kinetics of the Tetradecane release was measured for three formulations containing different concentrations of hydrophilic surfactant (2%, 4%, and 7%). A new mass transfer model derived from the shrinking core model was developed. The values of the model parameters deduced from the least-squares fittings led to the determination of the Tetradecane diffusivity. Thus, the preponderant mechanism of mass transfer was proved to be micellar diffusion and not molecular diffusion. This conclusion was confirmed by considering the effect of the change in the hydrophilic surfactant concentration.

Liquid–solid equilibria under high pressure of Tetradecane + pentadecane and Tetradecane + hexadecane binary systems
Fluid Phase Equilibria, 2005Co-Authors: Michel Milhet, Jérôme Pauly, J. Coutinho, M. Dirand, Jean-luc DaridonAbstract:The crystallization temperatures of two binary systems – Tetradecane + hexadecane and Tetradecane + pentadecane – were measured under high pressure up to 100 MPa using a polar microscopy device. The slopes of the melting curves in the (T, P) diagram show a dependence on the nature of the different solid phases that can appear. The effect of pressure on the liquidus curve in a (T, x) diagram is discussed and represented in the last part of this work with an excess Gibbs energy model, slightly modified to take the different solid phases into account.
