  • Patent number: 4457904
    Abstract: Hydrogen cyanide is produced from ammonia and carbon monoxide, or gases containing these compounds, while substantially avoiding the water shift reaction, by passing these compounds in contact with catalyst masses (for example, alumina-silica molecular sieves) having a high protonic acid content. Protonic acid content can be measured by ammonium acetate titration.
    Type: Grant
    Filed: August 9, 1982
    Date of Patent: July 3, 1984
    Assignee: Monsanto Company
    Inventors: James W. Gambell, Steven R. Auvil
  • Patent number: 4272451
    Abstract: In the process for preparing acetonitrile from CO, NH.sub.3 and H.sub.2, molybdenum catalysts containing manganese or alkaline earths, and optionally alkali metals, are employed to improve selectivity to acetonitrile.
    Type: Grant
    Filed: December 26, 1979
    Date of Patent: June 9, 1981
    Assignee: Monsanto Company
    Inventors: James W. Gambell, Steven R. Auvil
  • Patent number: 4272452
    Abstract: A process for preparing acetonitrile by reaction of carbon monoxide, ammonia and hydrogen at elevated temperature in contact with metal-containing catalysts, in which carbon dioxide is utilized to improve selectivity to acetonitrile. At elevated pressure, more than 2 moles carbon dioxide per mole carbon monoxide can be used effectively.
