Description of key information

Henry's Law Constant (HLC): Calculated HLC for the submission substance at environmental temperature (12°C): 2.7E05 Pa m3mol-1

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
270 000
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). No measured value for this parameter is available. The HLC can be estimated from the ratio of the vapour pressure (VP) to the water solubility (WS).

HLC = (VP x MW)/WS

Where MW is molecular weight.

The calculated HLC value for the parent submission substance at environmental temperature (12°C) is very high, 2.7E05 Pa m3mol-1 (taken from EUSES 2.1.2).
