  • Catalyst and process for the conversion of methanol to acetaldehyde
    Patent number: 4374752
    Abstract: A catalyst mixture is made with improved activity and selectivity to acetaldehyde by using an inert diluent and specifically defined concentrations of cobalt, a halide, a trivalent phosphorus compound, and the inert diluent. Use of the trivalent phosphorus compound significantly inhibits corrosion of the reactor metal.
    Type: Grant
    Filed: June 30, 1981

    Assignee: Union Carbide Corporation
    Inventors: Benny J. Argento, Wellington E. Walker, deceased, Rocco A. Fiato
  • Process for the selective hydroformylation of methanol to acetaldehyde
    Patent number: 4337365
    Abstract: A process for the production of acetaldehyde from the cobalt-catalyzed, iodide-promoted reaction of methanol, hydrogen and carbon monoxide, attaining (a) selectivity to acetaldehyde heretofore unachievable and (b) high methanol conversion, wherein the reaction is carried out in an inert solvent at a temperature of from 100.degree. C. to 180.degree. C. with an iodide to cobalt mole ratio of from 2:1 to 100:1.
