Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Any other information on results incl. tables

Henry's law constant (25°C) calculated with HENRYWIN v.3.10.

Bond method: 9.91e-8 atm.m3/mol = 0.0101 Pa.m3/mol (4.05e-6 unitless)

Group method: 1.44e-9 atm.m3/mol = 0.000146 Pa.m3/mol (5.89e-8 unitless)

Average=0.005Pa.m3/mol, which is also very close to the value derived from the figures for water solubility and vapour pressure cited in chapter 4.

Applicant's summary and conclusion

Executive summary:

There is no experimentally derived value for the Henry's constant available. Calculated values vary by almost two orders of magnitude between 0.0001 and 0.01Pa.m3/mol. A figure of 0.004Pa.m3/mol can be derived from the figures cited for vapour pressure and water solubility in this dossier. Overall, a value of 0.005Pa.m3/mol is used.
