Applicant's summary and conclusion

Conclusions:
log Pow of Alkenes, C11-12, hydroformylation products, low boiling: 6.9 at 25 °C
Executive summary:

The log Pow of Alkenes, C11 -12, hydroformylation products, low boiling was determined according to OECD 117.

The log Pow versus log K values of the reference substances (Thymol, Benzyl benzoate, Bibenzyl, 1 -Dodecanol and Tetradecanol) was plotted . The resulting equation was used to calculate the log Pow of the test substance: log Pow of Alkenes, C11-12, hydroformylation products, low boiling: 7.0 at 25 °C.
