(Liquid+liquid) equilibria for (water+1-propanol+Diisopropyl Ether+octane, or methylbenzene, or heptane) systems at T =298.15K
The Journal of Chemical Thermodynamics, 2015Co-Authors: Xiaoming Zhou, Yao Chen, Cui Wang, Jitai Guo, Caiyu WenAbstract:Abstract (Liquid + liquid) equilibria (LLE) data were presented for one ternary system of {water + octane + Diisopropyl Ether (DIPE)} and three quaternary systems of (water + 1-propanol + DIPE + octane, or methylbenzene, or heptane) at T = 298.15 K and p = 100 kPa. The experimental LLE data were correlated with the modified and extended UNIQUAC models. Distribution coefficients were derived from the experimental LLE data to evaluate the solubility behavior of components in organic and aqueous phases.

liquid liquid equilibria of oxygenate fuel additives with water at 298 15 k ternary and quaternary aqueous systems of Diisopropyl Ether and hydrocarbons with 2 propanol
Journal of Solution Chemistry, 2005Co-Authors: Yao Chen, Yanhui DongAbstract:Experimental tie-line data were determined for one ternary system, water + Diisopropyl Ether + n-heptane and two quaternary systems, water + Diisopropyl Ether + 2-propanol + n-heptane or toluene at 298.15 K and ambient pressure. The experimental liquid–liquid equilibrium data were successfully correlated using a modified UNIQUAC model with ternary and quaternary mixture parameters, in addition to the binary ones.

Azeotropic distillation for 1-propanol dehydration with Diisopropyl Ether as entrainer: Equilibrium data and process simulation
Separation and Purification Technology, 2019Co-Authors: Jordi Pla-franco, Estela Lladosa, Sonia Loras, Juan B. MontónAbstract:Abstract Azeotropic distillation process is widely used to separate non-ideal binary mixtures into their constituent pure components. 1-Propanol dehydration was used as case study and Diisopropyl Ether was analysed as possible entrainer in an azeotropic distillation. The separation of some alcohols from their aqueous solution is a challenging task because these aqueous mixture forms minimum boiling azeotrope. In this way, isobaric vapor-liquid and vapour-liquid-liquid equilibrium data were measured for the 1-propanol+ water + Diisopropyl Ether ternary mixture at 101.3 kPa. The data were correlated by NRTL and UNIQUAC models. A separation sequence (a decanter and a single-feed distillation column) for 1-propanol dehydration using Diisopropyl Ether was proposed. The simulation of the separation sequence was carried out satisfactorily by Aspen Hysys® using the thermodynamic model NRTL with the binary parameters obtained in this work. Moreover, the effect of temperature decantation was investigated in order to reduce the energy demand of the process.

Isobaric Vapor−Liquid Equilibria for Binary and Ternary Mixtures of Diisopropyl Ether, 2-Propyl Alcohol, and n-Butyl Propionate at 101.3 kPa
Journal of Chemical & Engineering Data, 2009Co-Authors: Estela Lladosa, Juan B. Montón, M C Burguet, Roberto BavieraAbstract:Consistent vapor−liquid equilibrium data at 101.3 kPa have been determined for the ternary system Diisopropyl Ether (1) + 2-propyl alcohol (2) + n-butyl propionate (3) and two constituent binary systems: Diisopropyl Ether (1) + n-butyl propionate (3) and 2-propyl alcohol (2) + n-butyl propionate (3). The Diisopropyl Ether (1) + n-butyl propionate (3) system does not present deviation from ideal behavior, and the 2-propyl alcohol (2) + n-butyl propionate (3) system shows light positive deviation from Raoult’s law. The activity coefficients of the solutions were correlated with their compositions by the Wilson, NRTL, and UNIQUAC models. Wisniak−Tamir equations were used to correlate the boiling points of the solutions with its composition. The binary VLE data measured in the present study passed the thermodynamic consistency test of Fredeslund et al. The ternary system is very well predicted from binary interaction parameters and passed both the Wisniak L−W and McDermott−Ellis consistency tests. The change ...

The binary vapour–liquid equilibrium data were correlated using the Wilson and NRTL equations by means of a robust algorithm for processing all isotherms togEther. The resulting parameters were then used to calculate phase behaviour in the ternary system and to comparison the calculated with experimental data.
