After evaporation or exposure to air 4-nitrotoluene-2-sulphonic acid will be slowly degraded by photochemical processes.
The rate constant for the reaction of 4-nitrotoluene-2-sulphonic acid
with hydroxyl radicals in the atmosphere was estimated by the SRC AOPWin
v1.92 program as 0.412E-12 cm³/molecule*s. From this rate constant
half-life for the reaction of OH radicals with
4-nitrotoluene-2-sulphonic acid is calculated as 38.94 days assuming a
24h-day (BASF SE 2009).
