Endpoint:
Henry's law constant
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Non-GLP; non-guideline; Information from published handbook, data compendium, review article or other reference text; acceptable with restrictions.
Principles of method if other than guideline:
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

Conclusions:
The Henry's Law Constant of 1,3,5-trimethylbenzene is 781 Pa.m3/mol.
Executive summary:

Mesitylene (1,3,5-trimethylbenzene) has a Henry's Law Constant of 781 Pa.m3/mol. No information on the methods used is available. However, this information is taken from a reliable peer reviewed handbook (Lide 2008) and is considered reliable and suitable for use for this endpoint.

Description of key information

1,3,5-trimethylbenzene has a Henry's Law Constant of 781 Pa.m3/mol.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
781

Additional information

1,3,5 -Trimethylbenzene has a Henry's Law Constant of 781 Pa.m3/mol. No information on the methods used is available. However, this information is taken from a reliable peer reviewed handbook (Lide 2008) and is considered reliable and suitable for use for this endpoint.

This is supported by a calculated Henry's Law Constant for 1,3,5-trimethylbenzene of 798 Pa.m3/mol. The value has been calculated based on the physico-chemical characteristics of the substance and the equation set out in the Technical Guidance Document Chapter R16 (ECHA 2012).
