Description of key information

Degradation of tetrachloroethylene in water by hydrolysis is very slow, with a half-life of 8.8 months.

Key value for chemical safety assessment

Half-life for hydrolysis:
1 000 000 yr
at the temperature of:
298 K

Additional information

Hydrolysis is not expected to be an important removal process for tetrachloroethylene. Half-lives in the range from 8.8 months to several million years have been reported (Dilling et al., 1975; Jeffers et al 1989).
