Description of key information

Log Kaw: 3.01 at 23.6°C.
HLC: 2520000 Pa m3 mol-1 at 23.6°C.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
2 520 000
at the temperature of:
23.6 °C

Additional information

A log Kaw of 3.01 (Kaw = 1023) at 23.6°C was determined in a reliable study conducted according to generally accepted scientific principles.

This is equivalent to Henry's Law Constant (HLC) of 2520000 Pa m3 mol-1.

(HLC = Kaw x RT)
