Description of key information
The calculated Henrys Law constant is 623 Pa m³/mol for the xylene isomers and 800-900 Pa.m3/mol for ethylbenzene.
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 of the xylene isomers and ethylbenzene have been calculated by a QSAR model recommended by ECHA (2008) Guidance on information requirements and chemical safety assessment R7a Endpoint specific guidance. The calculated value indicate that volatilisation from water is expected to occur at a rapid rate. The data are supported by results 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).
