The solubility of chlorobenzene was measured in subcritical water using a fused silica capillary reactor (FSCR) combined with a microscope recorder system to capture the images and identify the temperature of total dissolution. The solubility of chlorobenzene was found to vary between 43.5 mg g(-1) in water at 173.3 C and 71.4 mg g(-1) in water at 266.9 degrees C, increasing linearly with temperature. A new approximation model was developed to predict the solubility of chlorobenzene in subcritical water at elevated temperatures. This visualization in the FSCR method does not require sampling and subsequent analysis, and it has a great potential for the solubility determinations of other organic or inorganic materials.
