The HPLC method was used to determine the log Pow of
2-ethylanthraquinone. The log Pow is 4.6 ± 0.2 .
The log Kow of 2-ethylanthraquinone was determined to be 4.6 ± 0.2.
The log Kow of 2-ethylanthraquinone is reported in two papers. Bruijn et
al. (1989) determined the Kow with the slow-stirring method and Klein et
al (1988) determined the Kow with the HPLC method which later became the
basis for OECD TG 117. Both methods are suitable to determine relatively
high Kows. The reported log Kows are 4.370 ± 0.037 (Bruijn et al, 1989)
and 4.6 ± 0.2 (Klein et al, 1988), respectively. As the method used by
Klein et al (1988) is similar to the present-day OECD TG 117, log Kow =
4.6 ± 0.2 was chosen as the key value for the chemical safety
assessment. This value is supported by a QSAR predicting a log Kow of
