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 Góral. 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.
