Partition coefficient results for each sample:
Organic/Aqueous Volume Ratio
Mean Partition Coefficient
1.83 x 10-2
1.75 x 10-2
1.41 x 10-2
8.70 x 10-3

The partition coefficient for acrylonitrile was determined using a shake
flask method following EU Method A8 and OECD Method 107. Sample analysis
was performed using a validated Gas Chromatography method. Under these
conditions, the mean partition coefficient of acrylonitrile was
determined to be 1.04 at 21.0 ± 0.2oC, log10 Pow
1.65x10-2. The pH values of the samples ranged from 7.6 to
The octanol-water partition coefficient (log Pow) of the test substance
is reported to be 0.11 at 25 ˚C.
The Log Pow for acrylonitrile is reported to be 0.25 at 25 oC.
A shake flask determination reported the partition coefficient as 1.04
at 21 oC, log10 Pow 1.65x10-2. The Log
Pow for acrylonitrile is also reported to be 0.08-0.25 at 25 oC.
The Log Powfor acrylonitrile is reported to be 0.25 at 25 oC
(Pratesi et al., 1979), 0.11 at 25 oC (CITI, 1996) and
0.08 at 25 oC (BASF AG). The partition coefficient was
measured using a shake flask method (Butler et al., 2014) to be
1.04 at 21 oC (log10 Pow 1.65x10-2).
