A binary ethanol-xylene mixture of known composition was prepared in a conical flask with silicone stopper to prevent evaporation. The mixture was placed in a thermostated vessel, agitated by a magnetic stirrer and titrated through a needle of the syringe with water until two phases were observed. The result was checked by another ternary mixture, of the same composition as above: (a) titrated with one of the pure components until the turbidity disappeared, (b) by reappearance of turbidity by lowering the temperature about 0.5 °C. The two-phase mixture was placed in a 50 mL glass-stoppered test tube at temperature of 25 °C, shaken vigorously, kept for nearly 2 h in a constant temperature water bath, and after separation each layer was pipetted for sampling. Refractive index and density of each phase were measured and composition was found from the calibration curves constructed during solubility measurements. When mixtures were not separated clearly after several hours, a centrifuge was used to obtain separation. The International Union of Pure and Applied Chemistry Nam, S.; Hayakawa, T.; Fujita, S.; J.
