Description of key information

Benzene has a Henry's Law Constant of 415 Pa.m3/mol.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
415

Additional information

Benzene has a Henry's Law Constant of 415 Pa.m3/mol. The value has been calculated based on the physico-chemical properties of the substance and the equation set out in the Guidance R16 (ECHA 2012). The result is supported by data from the CRC Handbook (Lide 2008), which gives a Henry's Law Constant of 557 Pa.m3/mol. No information on the methods used is available but this information is taken from a reliable peer reviewed handbook and is considered reliable and suitable for use for this endpoint.
