Recommended liquid-liquid equilibrium data. Part 1. Binary alkane-water systems

The recommended liquid–liquid equilibrium (LLE) data for 32 binary n-alkane, isoalkane, and cycloalkane–water systems have been obtained after critical evaluation of all data (345 data sets) reported in the open literature up to the end of 2002. The evaluation of the alkane solubility data was based on a generalized equation, which allows prediction of the alkane solubility as a function of temperature. Using the predicted alkane solubilities the concentration of water in the alkane rich phase was calculated. The LLE calculations were performed with the equation of state appended with a chemical term (EoSC) proposed by Goral. The experimental solubilities of water in various alkanes were compared to each other and to the calculated values. The recommended data are presented in the form of individual pages containing tables, all the references, and optionally figures.

Recommended Liquid–Liquid Equilibrium Data. Part 4. 1-Alkanol–Water Systems

The recommended liquid–liquid equilibrium (LLE) data for 19 binary 1-alkanol–water systems have been obtained after critical evaluation of all data (527 data sets) reported in the open literature up to the end of 2004. An equation for prediction of the 1-alkanol solubility was developed. The predicted 1-alkanol solubility was used for calculation of water solubility in the second liquid phase. The LLE calculations were done with the equation of state appended with a chemical term proposed by Goral. The recommended data were presented in the form of individual pages containing tables and all the references.

Recommended Liquid–Liquid Equilibrium Data. Part 3. Alkylbenzene–Water Systems

The recommended liquid–liquid equilibrium (LLE) data for 21 binary alkylbenzene–water systems have been obtained after critical evaluation of all data (392 data sets) reported in the open literature up to the middle of 2003. An equation for prediction of the alkylbenzene solubilities was developed. The predicted alkylbenzene solubilities were used for calculation of water solubility in the second liquid phase. The LLE calculations were done with the equation of state appended with a chemical term proposed by Goral. The recommended data were presented in the form of individual pages containing tables, all the references, and optionally figures.

A new modification of the UNIQUAC equation including temperature dependent parameters

Abstract The UNIQUAC equation was modified by introduction of a linear temperature dependence of the volume and surface area parameters, ri and qi. The slope of ri and qi functions were found to be the same for hydrocarbons and pyridine. The modified equation was used for prediction of vapor–liquid equilibria (VLE) in binary mixtures of hydrocarbons and pyridine with hydrocarbons as well as for the prediction of the excess enthalpy (HE) in binary mixtures formed by pyridine with aliphatic alkanes. The results obtained were compared with predictions by UNIFAC and further with UNIQUAC equation and its modification involving temperature dependant coordination number z. The proposed temperature dependence of the ri and qi parameters enables prediction of the VLE at various temperatures and leads to reasonable values of HE. The necessary input reduces to one set of isothermal VLE data. One set of UNIQUAC interaction parameters uij is sufficient for representation of VLE in a wide range of temperature and to obtain a reasonable prediction of HE.

Recommended Liquid–Liquid Equilibrium Data. Part 2. Unsaturated Hydrocarbon–Water Systems

The recommended liquid–liquid equilibrium (LLE) data for 24 binary unsaturated hydrocarbon–water systems have been obtained after critical evaluation of all data (80 data sets) reported in the open literature up to the middle of 2003. A new equation was developed for prediction of the unsaturated hydrocarbon solubility. Using the predicted hydrocarbon solubilities the concentration of water in the second liquid phase was calculated. The LLE calculations were performed with the equation of state appended with a chemical term (EoSC). The recommended data were presented in the form of individual pages containing tables, all the references, and optionally figures.
