  • Preparation of ethylidene diacetate
    Patent number: 4581473
    Abstract: Process for the preparation of ethylidene diacetate by hydrogenating acetic anhydride in the presence of a homogeneous rhodium catalyst, methyl iodide and lithium iodide.
    Type: Grant
    Filed: January 30, 1981
    Date of Patent: April 8, 1986
    Assignee: Eastman Kodak Company
    Inventor: Stanley W. Polichnowski
  • 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
