  • Methods for producing cycloheptatriene
    Patent number: 8692042
    Abstract: This invention relates to methods for producing cycloheptatriene from at least 7,7-dichloronorcarane and a liquid component comprising a C8 to C30 succinic anhydride, a carboxylic acid, or a C8 to C30 alkyldimethylamine at about 205 deg. C. to about 230 deg. C.
    Type: Grant
    Filed: February 22, 2011
    Date of Patent: April 8, 2014
    Assignee: Albemarle Corporation
    Inventors: Richmond M. Starrett, Christopher D. Claeboe, Anthony F. Skufca, Joseph H. Miller
  • Processes for preparing triphenylene
    Patent number: 8575412
    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° C. to form a reaction mixture, heating the reaction mixture to at least about 180° C. but lower than the boiling point of the aliphatic solvent, maintaining the temperature of the reaction mixture at 180° 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.
    Type: Grant
