EC number: 292-607-4
CAS number: 90640-86-1
Distillate from the fractional distillation of coal tar of bituminous coal, with boiling range of 240°C to 400°C (464°F to 752°F). Composed primarily of tri- and polynuclear hydrocarbons and heterocyclic compounds.
The logPow of 4.92 of Distillates (coal tar), heavy oils (anthracene oil >50 ppm BaP, AOH [CAS no. 90640-86-1]) is estimated as the arithmetic mean of the three key components in AOH (see above Table 2):Phenanthrene: logPow = 4.57 Fluoranthene: logPow = 5.20 Pyrene: logPow = 4.98
In a standard study using the HPLC method (OECD 117), the log Pow
values of AOH constituents ranged from 4.43 to 6.33
The GC-analytical composition of AOH confirms that constituents
present in AOH cover the Pow range from fluorene/phenanthrene to
The large similarity of log Pow values of the
selected key components and their already published log Pow has also
been confirmed by this HPLC test.
Therefore, the mean value of phenanthrene,
fluoranthene, and pyrene adopted as a log Pow for the total UVCB
substance is continued to be used for risk assessment based on published
values (data from EU 2008: Risk Assessment of Pitch, Coal Tar, high
Phenanthrene: log Pow = 4.57
Fluoranthene: log Pow = 5.20
Pyrene: log Pow = 4.98
