Description of key information

Henry's Law constant: 0.051 Pa-m3/mole

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.051
at the temperature of:
25 °C

Additional information

The Henry's Law constants were estimated using the software HENRYWIN (v3.20).

Using bond and group contribution, HLC values have the same order of magnitude; for further assessments was selected the average of them:

 

HLC= (HLCB+ HLCG) / 2= 0.051 Pa-m3/mole
