Description of key information
The Henry's Law Constant (HLC) of 1,6-Divinylperfluorohexane is calculated to be 263952 Pa·m3/mol.
Basing on such value 1,6-Divinylperfluorohexane is anticipated to have rapid volatilization from water.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 263 952
- at the temperature of:
- 20 °C
Additional information
The Henry's Law Constant (HLC) of 1,6-Divinylperfluorohexane is calculated according to the following equation:
Henry's Law Constant (HLC) = (VP x MOLW) / WS
where:
VP = Vapour pressure (Pa) = 1200 Pa (at 20°C)
MOLW = Molecular Weight (g/mol) = 354,1355 g/mol
WS = Water solubility (mg/L) = 1.61 mg/L (at 20°C)
(Reference: Guidance on Information Requirements and Chemical Safety Assessment_ Chapter R.16: Environmental Exposure Estimation_ Version 3_Equation R.16-4)
As reported in Guidance on Information Requirements and Chemical Safety Assessment_Chapter R.7a_v.6., substances with HLC values around 100 Pa·m3/mol, will have a rapid volatilization from water.
Basing on the calculated Henry’s Law constant value, volatilization of 1,6 -Divinylperfluorohexane from water is expected to be very rapid.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
