Process for the preparation of anthraquinones |
| abstract |
Production of anthraquinones by oxidation of (o-dihalomethyl) diphenyl-dihalomethane compounds with nitric acid in the presence of sulfuric acid at elevated temperature. The compounds which can be prepared by the process of the invention are valuable starting materials for numerous syntheses, in particular of dyes. |
