o-dichlorbenzene is stable in aqueous solution (15 mg/l) for
2 months at 4 degree C.
Hydrolysis of o-dichlorobenzene under conditions obtaining
in the environment is improbable.

Conclusions:
o-dichlorbenzene is stable in aqueous solution (15 mg/l) for 2 months at 4 degree C. Hydrolysis of o-dichlorobenzene under conditions obtaining in the environment is improbable.
Executive summary:

o-dichlorbenzene is stable in aqueous solution (15 mg/l) for 2 months at 4 degree C.
Hydrolysis of o-dichlorobenzene under conditions obtaining in the environment is improbable.

Description of key information

In view of the drastic conditions (high alkalinity and temperatures) required to exchange chlorine for a hydroxyl group, hydrolysis of o-dichlorobenzene under conditions obtaining in the environment is improbable.

Key value for chemical safety assessment
