Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
From the water surface, the substance will not evaporate into the atmosphere.
Key value for chemical safety assessment
- at the temperature of:
- 25 °C
Additional information
No experimental data is available for DL-alpha-methylbenzylamine (CAS 618-36-0). Therefore the Henry's Law constant was estimated.
The Henry's Law constant was calculated to be 8.23 E-02 Pa*m³/mol according to the bond estimation method of the HENRYWIN Program (v3.20) of EPI Suite v4.10 (BASF SE, 2011). This value is representative for the uncharged molecule. At environmental conditions the molecule is expected to be ionised, therefore a pH-corrected Koc was calculated according to the REACH Guidance document (2008). The resulting Henry's Law constant for the environmentally relevant pH range of 4 to 9 are listed below (BASF SE, 2011).
pH 4: 6.85 E-07 Pa*m³/mol
pH 7: 6.79 E-04 Pa*m³/mol
pH 9: 3.74 E-02 Pa*m³/mol
Based on these values the substance will not evaporate into the atmosphere from the water surface.
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.
