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):
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).
