  • Purification of carboxyl streams
    Patent number: 5399752
    Abstract: Disclosed is a process for the purification of carboxyl streams such as product streams comprising one or more carboxyl compounds selected from carboxylic acids, carboxylic anhydrides and alkylidene dicarboxylates. The process provides a means for the reduction of the iodine content of carboxyl compound product streams which are contaminated with one or more iodine compounds.
    Type: Grant
    Filed: May 31, 1994
    Date of Patent: March 21, 1995
    Assignee: Eastman Chemical Company
    Inventors: Stanley J. Okrasinski, Regina M. Moncier, Patricia N. Mercer, Dewey W. Fuller, Jr., Steven L. Cook
  • Continuous process for the preparation of acetic anhydride or mixtures of acetic anhydride and acetic acid
    Patent number: 5292948
    Abstract: Disclosed is a continuous process for the preparation of acetic anhydride which comprises carbonylating a mixture comprising (i) methyl iodide and (ii) methyl acetate and/or dimethyl ether in the presence of a rhodium catalyst and a promoter wherein the concentration of mesityl oxide in the carbonylation mixture is suppressed by the presence therein of at least 100 ppm of dissolved ferrous and/or cobaltous ion.
    Type: Grant
    Filed: May 28, 1993
    Date of Patent: March 8, 1994

  • Method for purification of carboxylic acids and anhydrides
    Patent number: 5175363
    Abstract: Disclosed is a method for reducing olefinic impurities in solutions of carboxylic acids and/or anhydrides. The invention is especially useful for removing substantially all, i.e., greater than 90 percent of trace amounts of olefinic impurities.

    Filed: January 28, 1991
    Date of Patent: December 29, 1992
    Assignee: Eastman Kodak Company
    Inventors: Joseph R. Zoeller, Regina M. Moncier
  • Process for the preparation of .alpha.-iodocarbonyl compounds
    Patent number: 5144070
    Abstract: Disclosed is a process for the preparation of .alpha.-iodocarbonyl compounds such as .alpha.-iodocarboxylic acid anhydrides and .alpha.-iodoketones by the reaction of a carboxylic anhydride with molecular iodine. Hydrolysis of the .alpha.-iodocarboxylic acid anhydrides gives the corresponding .alpha.-iodocarboxylic acids.

  • Process for the coproduction of alkyl iodides and alpha-iodocarboxylic acids and/or anhydrides thereof
    Patent number: 5144067
    Abstract: Disclosed is a process for the coproduction of (1) an alkyl iodide and (2) an .alpha.-iodocarboxylic acid, a mono-.alpha.-iodocarboxylic anhydride or a mixture thereof which comprises contacting a mixture of an iodine compound and a carboxylic anhydride with a peroxide at an elevated temperature.
    Type: Grant
    Filed: September 29, 1989
    Date of Patent: September 1, 1992
    Assignee: Eastman Kodak Company
    Inventors: Joseph R. Zoeller, Michael R. Cushman, Regina M. Moncier, Brent A. Tennant
  • Process for decomposing .alpha.,.beta.-unsaturated carbonyl compounds in refining acetic anhydride and/or acetic acid
    Patent number: 5097069
    Abstract: Unsaturated ketones such as mesityl oxide may be removed from acetic anhydride, or mixtures of acetic anhydride and acetic acid, by heating a solution comprising (1) acetic anhydride, or a mixture of acetic anhydride and acetic acid, (2) an .alpha.,.beta.-unsaturated ketone, (3) ferrous (Fe II) and/or cobaltous (Co II) ion, (4) a cation selected from alkali metals, alkaline earth metals, quaternary organoammonium, quaternary organophosphonium and mixtures thereof, and (5) iodide ion.
    Type: Grant
