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.
