Accurate information on physicochemical properties of an organic contaminant is essential for predicting its environmental impact and fate. These properties also provide invaluable information for the overall understanding of environmental distribution, biotransformation, and potential treatment processes. In this study Sw (aqueous solubility), Kow (octanol-water partition coefficient), and KH (Henry's law constant) were determined for an IM (insensitive munitions) compound, MNA (N-methyl-4-nitroaniline), at 298.15 K, 308.15 K, and 318.15 K. Effect of ionic strength on solubility, using electrolytes such as NaCl and CaCl2, was also studied. The data on the physicochemical parameters were correlated using the standard van't Hoff equation. All three properties exhibited a linear relationship with reciprocal temperature. The enthalpy and entropy of phase transfer were derived from the experimental data.
