  • Process for preparing iodinated substituted aromatic compounds
    Patent number: 4778940
    Abstract: A process for iodinating an aromatic compound in which a source of iodine is reacted with the aromatic compound in the presence of oxygen over a non-acid catalyst wherein the aromatic compound has a fluoro, chloro, bromo, iodo, hydroxy or cyano group.
    Type: Grant
    Filed: March 25, 1987
    Date of Patent: October 18, 1988
    Assignee: Eastman Kodak Company
    Inventors: Mark Rule, Gerald C. Tustin, Donald W. Lane, Thomas H. Larkins
  • Low temperature oxyiodination of aromatic compounds
    Patent number: 4778939
    Abstract: The invention relates to a process for iodinating an aromatic compound which comprises reacting iodine and the aromatic compound over a non-acid catalyst, wherein the catalyst has been contacted with an alkali or alkaline earth metal salt, with a source of iodine and a source of molecular oxygen.
    Type: Grant
    Filed: March 25, 1987
    Date of Patent: October 18, 1988
    Assignee: Eastman Kodak Company
    Inventors: Gerald C. Tustin, Mark Rule
  • Processes for preparing iodinated aromatic compounds
    Patent number: 4746758
    Abstract: This invention relates to a process for iodination of aromatic compounds in the presence of oxygen over a zeolite catalyst.
    Type: Grant
    Filed: September 29, 1986
    Date of Patent: May 24, 1988
    Assignee: Eastman Kodak Company
    Inventors: Mark Rule, Donald W. Lane, Thomas H. Larkins, Jr., Gerald C. Tustin
  • Preparation of acetic anhydride
    Patent number: 4374070
    Abstract: The preparation of acetic anhydride by the carbonylation of methyl acetate in the presence of rhodium, an iodine compound and lithium at elevated temperatures and pressures is improved by the inclusion of about 2 to 7 volume percent hydrogen in the gas fed to the carbonylation reactor. The presence of hydrogen suppresses tar formation and increases reaction rate.
    Type: Grant
