Description of key information

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
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 to the water solubility.


Volatilisation from water is not relevant for dichloro(diphenyl)silane due to its very rapid hydrolysis in contact with water.

The calculated HLC value for diphenylsilanediol at 12 °C is low, 1.8 E-06 Pa m3mol-1.
