Administrative data
- Endpoint:
- hydrolysis
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- 3-chloropropene is hydrolised in water by neutral catalysed reactions to give alcohols. The half-life for hydrolysis is mainly independent from pH conditions and is approximately 8 days at 25 °C.
- Executive summary:
The available data indicate that 3-chloropropene is hydrolysed in water to give biodegradable alcohols. The rate constant for hydrolysis is 0.086 per day and the resulting half-life is approximately 8 days.
