ABSTRACT:
This invention provides processes for the production of benzene from anthracene, 9,10-anthraquinone from anthracene, and benzene from 9,10-anthraquinone. In the conversion of anthracene to 9,10-anthraquinone, anthracene is reacted with a molecular oxygen-containing gas (e.g., air) in the presence of a catalyst and promotor at an elevated temperature (65.degree. to 205.degree. C.). To convert 9,10-anthraquinone to benzene, the anthraquinone is thermally cracked, with or without a suitable catalyst, at a temperature of at least 425.degree. C. An example of a suitable catalyst is synthetic zeolite.
