Method/Apparatus/Procedure:
The titration method was used to measure solubility curve at 20 °C. Binary benzyl alcohol-toluene mixtures were titrated with water and water was titrated with binary benzyl alcohol-toluene mixtures. The analytical method was used to determine liquid-liquid-vapor equilibrium (LLVE) data at boiling temperature at 101.32 kPa. Samples of hot liquid organic rich phase taken from the apparatus were cooled to 20 °C and titrated with a binary benzyl-alcohol-toluene mixture (the mixture composition was the same as used to prepare the primary sample for LLVE measurements) until homogenization was obtained. The assumption was made that the ratio of benzyl alcohol to toluene in hot liquid phase was the same as at the beginning of experiment in binary mixture. The fraction of water rich phase was always small. The concentration was calculated from mass balance.
