pH value :
Method : other (measured)
Year : 1999
GLP : no data
Test substance : other TS: o-Toluidine, no purity specified

Partition coefficient : octanol-water
Log pow : 1.29 at °C
pH value :
Method : other (measured)
Year : 1971
GLP : no
Test substance : other TS: o-Toluidine, purity not specified
Test condition : At room temperature (20 - 25 °C)
Reliability : (2) valid with restrictions
Basic data given
09.11.2004 (35) (36) (37)
Method : other (measured)
Year : 2002
GLP : no data
Test substance : other TS: o-Toluidine, purity not specified
Remark : The partitioning parameters between water and fuel and between water
and isooctanate were determined because the contamination of
groundwater by fuel constituents from nonaqueous phase liquids is a
widespread problem.
Result : - Kfw (fuel): 12
[fuel used RON 98, premium grade: 9 % MTBE and 43 % aromatic
compounds].
- Kiw (isooctanate): 3.3
[value was taken from Abraham (1993)].
All values given at 25 °C.
Reliability : (2) valid with restrictions
Study well documented, meets generally accepted scientific principles
