86.8 Pa m3/mol at 23 °C (Nielsen)
A fairly broad range of values have been reported for the Henry's Law
constant (Handbook of Physical-Chemical Properties and Environmental
Fate for Organic Chemicals, Vol. III, Oxygen Containing Compounds, 2nd
Ed., 2006, CRC Press, p2267; NIST Chemistry Webbook). The value by
Nielsen (1994) is taken as one of the few experimentally determined
The Guidance on Information Requirements and Chemical Safety Assessment
Chapter R.7a: Endpoint Specific Guidance, Appendix R.7.1 -4 indicates
that substances with a Henry's Law constant of around 100 Pa m3/mol will
volatilise from water rapidly.
