ABSTRACT Anthracene is precipitated in improved purity and yield by cooling a creosote coal tar distillation fraction. A ketone such as acetone is added to the fraction before the anthracene precipitates. The ketone retains phenanthrene and/or carbazole in the liquid phase as the anthracene precipitates. If the ketone is then removed, the phenathrene and/or carbazole precipt- tates and can also be purified.
