Key value for chemical safety assessment

Log Kow (Log Pow):
2.63
at the temperature of:
25 °C

Additional information

Compilation of log Pow data of 1,2,3 -Trichloropropane:

 Data source  measured / calculated temperature °C  log Pow 
 SIDS dossier 2004 (data taken from MITI 1992)  measured   20 / 25 °C * 2.23 
SIDS dossier 2004 (data taken from Ruelle 2000)  calculated   20 / 25 °C * 2.54 
 NITE 2009 (data taken from CRC Handbook 84th ed.) measured  25 °C  2.63 
 Lide 2008 (CRC Handbook 89th ed.) measured  25 °C  2.63 

* No detailed information given on the temperature during measurement, however it is assumed that the temperature was in the usual range of 20 - 25 °C.

The log Pow values as shown above are consistent and indicate that the data set is robust. The preferred value is the log Pow as given by Lide 2008 (CRC Handbook 89th. ed.) and by NITE 2009, which is referring to the 84th. ed. of the CRC Handbook. These are also the two data sources which reported unambiguously clear the temperature during measurement.
