The stability of 1,4 -benzenediamine, N,N'-mixed phenyl and tolyl
derivatives (DAPD) was evaluated by testing (or modeling) the
transformation (and half-life) of the substance in different
environmental compartments. Phototransformation in air was modeled using
a QSAR (EpiWin) and was indicative of a short half life of the substance
in air (DT50 = 0.64hr).
Phototransformation in water was tested (McLaughlin, 2004) at two
different pHs (6 & 8) and indicated DT50 values adjusted for natural
sunshine of 0.94 and 1.78 days respectively.
Finally the potential of the substance to hydrolyse was evaluated. The
combined results of two studies indicate that no chemical reaction is
occurring between water and DAPD under the applied experimental
