2,4,6-Trinitrotoluene

CAS RN:118-96-7

Volatilization

The Henry's Law constant for 2,4,6-trinitrotoluene is estimated as 2.1X10-8 atm-cu m/mole(SRC) derived from its vapor pressure, 8.02X10-6 mm Hg(1), and water solubility, 115 mg/L(2). This Henry's Law constant indicates that 2,4,6-trinitrotoluene is expected to be essentially nonvolatile from water surfaces(3). 2,4,6-Trinitrotoluene is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1). Only 8-10% of 2,4,6-trinitrotoluene in solution was lost to evaporation over an 18 day stripping experiment in which waste water from a TNT manufacturing process was aerated(4).
