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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Henry's Law constant
Administrative data

Description of key information
The Henry's Law Constant for the xylene isomers is 623 Pa.m3/mol. The calculated Henrys Law Constant for ethylbenzene was 800 Pa.m3/mol. The lowest value calculated via teh group and bond contribution methods were used as the key value.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 623
- at the temperature of:
- 25 °C
Additional information
The Henry's Law Constant has been taken from QSAR estimates following the group and bond contribution methods. Also reported are the individual values for the isomers from the experimental database and calculations using estimated vapour pressure and water solubility. These results are supported by data from the CRC Handbook (Lide 2008).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
