Description of key information
No reliable experimental study was identified for 1,3,5-trimethylbenzene, therefore Koc and Log Koc were calculated, using the Log Kow of 3.42 in accordance with the method defined in the TGD (2003), to be 741.65 and 2.87 respectively. Koc and log Koc values of 472 and 2.67 respectively, reported in USEPA report (1994), have an unknown reliability but are considered suitable as a supporting study.
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. The supporting study gives a result of 798 Pa.m3/mol, calculated from the water solubility and vapour pressure.
Additional information
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.
