  • Process for preparing ethylidene diacetate
    Patent number: 5138093
    Abstract: Ethylidene diacetate is prepared by treating at least one member of the group consisting of methyl acetate and dimethyl ether with carbon monoxide in the presence of a source of halide under substantially anhydrous conditions.
    Type: Grant
    Filed: February 5, 1976
    Date of Patent: August 11, 1992
    Assignee: Eastman Kodak Company
    Inventors: Nabil Rizkalla, Charles N. Winnick
  • Process for preparing a silver catalyst
    Patent number: 4342667
    Abstract: A supported silver catalyst for oxidation of ethylene to ethylene oxide is prepared by impregnation of the support, activation, and solvent washing, with each step being carried out at a relatively low temperature. Silver so deposited has an average particle diameter of about 0.5-0.7 microns and is capable of being promoted by post-deposition of alkali metals such as cesium, rubidium, and potassium.
    Type: Grant
    Filed: March 26, 1979
    Date of Patent: August 3, 1982
    Assignee: The Halcon SD Group, Inc.
    Inventors: William D. Armstrong, Charles N. Winnick
  • Catalytic process for dehydration of alcohols
    Patent number: 4207424
    Abstract: An improved process for the catalytic dehydration of alcohols to form unsaturated organic compounds is provided in which an alcohol is dehydrated in the presence of alumina catalysts which are pre-treated with an organic silylating agent at elevated temperature.
    Type: Grant
    Filed: August 9, 1978
    Date of Patent: June 10, 1980
    Assignee: Halcon Research & Development Corporation
    Inventor: Charles N. Winnick
  • Chemical process for producing isoprene by pyrolysis of allylic esters
    Patent number: 4045419
    Abstract: Process for preparing unsaturated esters by reacting an olefin having an allylic hydrogen atom with an ester forming material in the presence of oxygen and a catalyst selected from the group consisting of mercury, selenium or tellurium. The unsaturated ester may be converted to a polyunsaturated compound by pyrolysis.
