Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The catabolism of 1,2-dichloropropane has been tested in Pyrex vessels containing demineralized water. As Pyrex absorbs wave-length < 290 nm, the sunlight spectrum of the troposphere was simulated during the irradiation. The transformation rate was 4 % after 180 minutes irradiation with 5.65 mg 1,2-dichloropropane/l starting concentration and was 8 % after 120 min irradiation with a starting concentration of 10.17 mg 1,2-dichloropropane/l. This results in the half-life times estimated at ca. 50.9 hours and 16.6 hours.
