Description of key information
The Henry's Law Constant (HLC) of SOLVENT N1 is calculated to be ca. 21 x E104 Pa·m3/mol.
Basing on such value SOLVENT N1 is anticipated to have rapid volatilization from water.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 206 559
- at the temperature of:
- 20 °C
Additional information
The Henry's Law Constant (HLC) of SOLVENT N1 is calculated according to the following equation:
Henry's Law Constant (HLC) = (VP x MOLW) / WS
(Reference: Guidance on Information Requirements and Chemical Safety Assessment_ Chapter R.16:
Environmental Exposure Estimation_ Version 3_Equation R.16-4)
where:
VP = Vapour pressure (Pa) of SOLVENT N1 = 30110 Pa (at 20°C)
MOLW = Molecular Weight (g/mol) = ca. 260 g/mol (weighted average for SOLVENT N1 reaction mass)
WS = Water solubility (mg/L) of SOLVENT N1= 37.9 mg/L (at 20°C)
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 SOLVENT N1 from water is expected to be very rapid.
