The average retention times of the reference
substances as well as the test substance, corrected for the dead time,
are presented in table IV. The theoretical log Kowvalues of
the reference substances were taken from OECD guideline 117. A complete
overview of the results is presented in Annex 2.
Average netretention time(min)
Figure 1 in the attachment displays the
graph of the theoretical values of log Kowand the average log
k of the reference substances. Figure 2 shows an example of a
HPLC-chromatogram from the analysis performed according to the test set
The partition coefficient n-octanol/water (Kow)
bis(2-ethylperoxyhexanoate)was estimated using the High Performance
Liquid Chromatography (HPLC) method. The Kowtest was
performed in accordance with the OECD guideline 117 with one
modification, the reference substances and test substances were
dissolved in methanol. The data on the partition coefficient can be used
to predict the adsorption on soil and sediments and for establishing
quantitative structure-activity relationships for a wide range of
average measured log Kow value for 1,1,4,4-tetramethylbutane-1,4-diyl
bis(2-ethylperoxyhexanoate)as determined from the test was >6.5. As
estimation the log Kow value was calculated by extrapolation to be 7.1
The partition coefficient log Pow for
1,1,4,4-tetramethylbutane-1,4-diyl bis(2-ethylperoxyhexanoate) is
>6.5. As estimation the log Pow value was calculated by extrapolation
to be 7.1
