When referring to the compilation of Henry's Law Constants, please cite
R. Sander: Compilation of Henry's law constants (version 5.0.0) for
water as solvent, Atmos. Chem. Phys., 23, 10901-12440 (2023),
The publication from 2023 replaces that from 2015,
which is now obsolete. Please do not cite the old paper anymore.
I am looking forward to receiving information about additional data and
bug reports from the scientific community. However, please don't be too
disappointed in case I don't have the time to reply. Collecting Henry's
law constants is not my main job. It's just something I did because I
needed (and still need) them for my research. Before sending me an
email, please consider the following points:
- Converting between different definitions and units for Henry's law
constants can be quite tricky. I'm afraid I won't have the time to
answer individual questions on how to convert between one unit and
- Henry's law constants are used in several research areas, e.g.
pesticide control, waste water management, and atmospheric chemistry.
Since I'm an atmospheric chemist myself, I don't think I will be able to
help you with problems in the other research areas.

I received. For valuable discussions, bug reports, and also for
pointing out and sending copies of additional references to me, I

The web pages are hosted on a server at
the GWDG in
Göttingen, Germany. I would like to thank the IT group at the GWDG
for their support. Previously, the pages were hosted on the web server
of the satellite group in Mainz, for which I would like to thank T.
Wagner and R. Sörensen.
The NIST Chemistry
WebBook and PubChem were indispensable tools for obtaining
InChIKeys and CAS registry numbers. The Open Babel software was used a lot to convert
between SMILES and other chemical formats.
