ABSTRACT
The salting-out behavior of nitrobenzene (NB), 2-nitrotoluene (2-NT), and 3-nitrotoluene (3-NT) was determined from solubility measurements in pure water and seawater with ionic strengths ) (0.1662, 0.3352, 0.5071, and 0.6820) mol *L-1 at temperatures between (277 and 314) K. For all compounds tested, the solubility increased with increasing temperature. Solubility values in pure water compare well with previously reported values. As the ionic strength of the solution increased, the solubility of the organic compounds decreased. The average salting-out coefficients for NB, 2-NT, and 3-NT were (0.12, 0.14, and 0.14) L* mol-1, respectively, which are consistent with measurements for other nitroaromatic compounds. Over the temperature range examined, the salting-out coefficients did not vary significantly.
