Process for the isolation of carbazole and production of 9,10-dihydroanthracene from crude anthracene |
| abstract |
The present invention makes it possible to isolate carbazole and to produce simultaneously 9,10-dihydroanthracene from raw anthracene containing anthracene, carbazole, and phenanthrene. The method comprises a suspension crystallisation stage for the raw anthracene whereby enriched raw anthracene is formed, hydrogenated after separation and subsequently undergoes solvent crystallisation. The crystallised product thus obtained contains at least 90 % carbazole. |
