Process for preparing thioxanthone and derivatives thereof |
摘要 |
A process for preparing thioxanthone and derivatives thereof is disclosed. In the process, an aromatic compound, such as cumene, is reacted with thiosalicylic acid (TSA) or dithiosalicylic acid (DTSA) in the presence of sulfuric acid. The reaction mixture, which includes thioxanthone or a derivative thereof, is thereafter distilled under reduced pressure to recover the thioxanthone compound.
