Effects of pH and Temperature on the Aqueous Solubility and Dissolution Rate of 2,4,6-Trinitrotoluene (TNT), Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and Octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX)

Aqueous solubilities and dissolution rates are reported and examined for 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) over the pH range of (4.2−6.2) and the temperature range of (3.1−33.3) °C. Measurements were performed using high-pressure liquid chromatography with ultraviolet detection. Solubilities and dissolution rates were not statistically affected by pH within the experimental design limits. Correlations are proposed to estimate the aqueous solubility of these high explosives as a function of temperature.
