Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Estimated rate constant for reaction with atmospheric hydroxyl radicals is 59.75*E -12 cm³/molecule/s.

Key value for chemical safety assessment

Half-life in air:
6.44 h
Degradation rate constant with OH radicals:
0 cm³ molecule-1 d-1

Additional information

Half-life is estimated for the major component in the material derived from second-order rate constant, assuming a tropospheric hydroxyl radical concentration of 500,000 molecules OH/cm3, and 24-hr. The estimated rate constant is 59.75*E -12 cm³/molecule/s and the half-life is 6.44 hrs.
