Title: Processes for preparing triphenylene

Abstract: Processes are provided for producing triphenylene by combining at least dodecahydrotriphenylene, a dehydrogenation catalyst such as palladium on carbon, and an aliphatic solvent having a boiling point greater than 180.degree. C. to form a reaction mixture, heating the reaction mixture to at least about 180.degree. C. but lower than the boiling point of the aliphatic solvent, maintaining the temperature of the reaction mixture at 180.degree. C. but lower than the boiling point of the aliphatic solvent, and passing a purge fluid comprising an inert fluid through the reaction mixture, for a period of time adequate for production of triphenylene.
