Photodegradation in air:

The calculated atmospheric half-life of 4-chlorotoluene is 8.8 days (Bayer Industry Services, 2004).


As chlorine is a ring substituent, hydrolysis is not expected to be an important process in determining the environmental fate of p-chlorotoluene (Jaber, 1984). Neutral pH values when dissolved in water and stability are basic properties of chlorotoluenes (Rossberg, 2000).
