Description of key information
2,4,4-trimethylpentene has a Henry's Law Constant of 282971 Pa.m3/mol.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 282 971
Additional information
2,4,4 -trimethylpentene has a Henry's Law Constant of 282971 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 QSAR estimation (US EPA 2009).
The Henry's Law Constant has been taken from a QSAR estimate. The values determined using the group and bond contribution methods are 1.34 and 0.746 atm-m3/mol respectively.
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.
