Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

at the temperature of:
12 °C

Additional information

The transfer of a substance from the water phase to the gas phase can be estimated by means of the Henry’s Law Constant (HLC).

A log Kaw of 3.22 (Kaw = 1660) at 19.7°C was determined in a reliable study conducted according to generally accepted scientific principles.

This is equivalent to Henry's Law Constant (HLC) of 5410000 Pa m3 mol-1 at 19.7°C, 2590000 Pa m3 mol-1 at 12°C.

(HLC = Kaw x RT)
