Description of key information

Anthracene oil (BaP < 50 ppm, AOL) is a UVCB substance, for which no exact boiling point exists. The temperature range, in which 10 % to 90 % of the compound distils, is considered as relevant boiling range, in the case of anthracene oil (CCSG composite sample 07) ca. 300 - ca. 360 °C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

310 °C

Additional information

For risk assessment, the low end of the boiling range (approx. 10 - 20 % distillate) is adopted as relevant boiling point. Taking into account the distillation ranges determined from both, Koppers and RÜTGERS, the boiling point of anthracene oil (CCSG composite sample 07) is specified to be 310 °C. Due to slight modifications in composition of different lots/batches (UVCB substance), the specific boiling point/range of other individual anthracene oil batches may be somewhat different.
