Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

Endpoint:
hydrolysis
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The data is given presented in a peer-review article describing and summarising experimental rates for hydrolysis. The experimental design and conditions are not described. The data is nevertheless considered as reliable with restrictions.

3-Chloropropene was found to hydrolises in water by neutral catalysed reactions to give a variety of alcohols.
Dissipation DT50 of parent compound
pH:
7
Temp.:
25 °C
Hydrolysis rate constant:
ca. 0.086 d-1
DT50:
ca. 8 d
Type:
(pseudo-)first order (= half-life)
Remarks on result:
other: The estimated half-life was 8 days at ph 4 and 9 at 25 degrees C.
Other kinetic parameters:
The hydrolysis rate constant for 3-chloropene was determined to be approximately 0.09 day-1 for all pH buffers at 25 degrees C.
Details on results:
The estimated hydrolytic half-life of 3-chloropropene at pH 4, 7 and 9 at 25 degres C was 8 days.

Applicant's summary and conclusion

Validity criteria fulfilled:
not specified
Conclusions:
The estimated hydrolytic half-life of 3-chloropropene at pH 4, 7 and 9 at 25 degres C was 8 days. These data demonstrate that the hydrolytic half-life of 3-chloropropene is relatively indenpendent of pH.
Executive summary:

The estimated hydrolytic half-life of 3-chloropropene at pH 4, 7 and 9 at 25 degrees C was 8 days and is believed to be representative for AC Light Ends.
