Solubility of liquid organics of environmental interest in subcritical (hot/liquid) water from 298 K to 473 K

The solubilities of benzene, toluene, m-xylene, p-cymene, octane, 2,2,4-trimethylpentane (isooctane), tetrachloroethylene, 1,2-dichlorobenzene, and tetraethyltin were determined at temperatures ranging from 298 K to 473 K. Increasing the temperature up to 473 K increased the solubilities by a factor of similar to 10-250. For example, increasing the temperature from 298 K to 473 K increased the mole fraction solubility of tetraethyltin from (0.03 +/- 0.002) x 10(-7) to (8.8 +/- 0.6) x 10-7 but only increased the solubility of benzene from (4.0 +/- 0.1) x 10(-4) to (41 +/- 3) x 10(-4). Pressure had a minimal effect; for example, increasing the pressure from 65 to 400 bar at either 298 K or 473 K reduced the solubility of benzene by only similar to 20%.
