PROCESSES FOR PREPARING TRIPHENYLENE

摘要

pProcesses 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 18O°C to form a reaction mixture, heating the reaction mixture to at least about 18O°C but lower than the boiling point of the aliphatic solvent, maintaining the temperature of the reaction mixture at 18O°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./p [WO2010065216A2]
