ABSTRACT
The solubility of ethylbenzene, m-xylene, and benzene in water was determined using a laboratory-made system at temperatures ranging from 298 K to 473 K and a pressure of 50 bar. The solubility was enhanced by at least one order of magnitude by increasing temperature from ambient to 473 K. A simple approximation model was developed to predict the solubility of liquid organics in high-temperature water. This model delivers excellent estimation for the solubility of small molecules of liquid organic compounds in water at temperature at or higher than 373 K.
