  • Catalyst for preparation of 4-cyanothiazole
    Patent number: 4055511
    Abstract: 4-Cyanothiazole is prepared by the catalytic vapor phase ammoxidation of .DELTA.3-4-methylthiazoline or 4-methylthiazole, using as catalyst a novel composition comprising a slurried chromium cobalt molybdate. The process affords high selectivity in the production of 4-cyanothiazole.
    Type: Grant
    Filed: March 15, 1976
    Date of Patent: October 25, 1977
    Assignee: Merck & Co., Inc.
    Inventors: Glenn R. Elion, Arthur E. Klink
  • Catalyst for preparation of 4-cyanothiazole
    Patent number: 4055514
    Abstract: 4-Cyanothiazole is prepared by the catalytic vapor phase ammoxidation of 4-methylthiazole using a novel catalyst composition comprising a cobalt molybdate catalyst wetted with different levels of potassium hydroxide. The process affords high selectivity to the desired 4-cyanothiazole.
    Type: Grant
    Filed: March 15, 1976

  • Preparation of cyanopyridines
    Patent number: 3981879
    Abstract: Cyanopyridines are prepared by bringing a reactant stream comprising an alkyl substituted pyridine, ammonia, steam and oxygen into contact with a novel catalyst composition which results in high selectivity to the desired cyanopyridine.
    Type: Grant
