EC number: 242-056-0
CAS number: 18171-19-2
Henry's Law Constant:
Calculated HLC for the parent
substance: not relevant due to rapid hydrolysis in contact with water
Calculated HLC for silanol
hydrolysis product at 25°C: 1.1E-4 Pa m3/mol
HLC for methanol: 0.461 Pa m3/mol
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
Volatilisation from water is not
relevant for the parent substance due to its rapid hydrolysis in contact
For the silanol hydrolysis
product, 3-chloropropyl(methyl)silanediol, the predicted water
solubility limit cannot be validated accurately due to condensation
phenomena. The HLC can be estimated using the established Bond method
from HENRYWIN v. 3.20 within the EPIWeb suite v4.11. This method derives
the Henry's Law Constant directly from the structure, as the sum of the
bond contribution values for each chemical bond in the molecule. The
bond contribution values were determined based on least-square
regression analysis of measured HLCs for organic compounds.
The calculated HLC value for the
silanol hydrolysis product at 25°C is very low, 1.1E-4 Pa m3mol-1
(HenryWin v 3.20).
Methanol has a reported HLC value
of 0.461 Pa m3/mol at 25°C (OECD 2004).
