  • 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
  • Process for the manufacture of methanol and dimethyl ether
    Patent number: 5254596
    Abstract: Disclosed are chemically-mixed, titanium-zinc oxide catalysts and the use of the catalysts in the manufacture of methanol and dimethyl ether wherein synthesis gas is contacted at elevated temperatures and pressures with the catalyst.
    Type: Grant
    Filed: September 15, 1992
    Date of Patent: October 19, 1993
    Assignee: Eastman Kodak Company
    Inventors: Gether Irick, Jr., Patricia N. Mercer, Keneth E. Simmons
  • Preparation of alkyl (alkoxycarbonylcyclohexyl) cyclohexenecarboxylates and dialkyl biphenyldicarboxylates
    Patent number: 5194669
    Abstract: Disclosed are processes for the preparation of alkyl (alkoxycarbonylcyclohexyl)cyclohexenecarboxylates by the dimerization of alkyl 3-cyclohexenecarboxylates and the dehydrogenation of the alkyl (alkoxycarbonylcyclohexyl) cyclohexenecarboxylates to dialkyl biphenyldicarboxylates. The processes are especially useful for the preparation of dialkyl 4,4'-biphenyldicarboxylates which are intermediates in the preparation of high performance polyesters.
