  • Process for the oxidation of alkanes
    Patent number: 6492548
    Abstract: Processes are disclosed for the oxidation of alkanes such as, for example, propane, to form unsaturated carboxylic aldehydes and acids such as, for example, acrolein and acrylic acid. The processes utilize oxygen and recycle alkanes, e.g. propane, to the aldehyde reactor. The presence of the alkane-to-aldehyde reaction can enhance the efficiency of the processes.
    Type: Grant
    Filed: September 20, 2000
    Date of Patent: December 10, 2002
    Assignee: Union Carbide Chemicals & Plastics Technology Corporation
    Inventors: Jonathan L Brockwell, Mark A Young, William G Etzkorn, Barbara K Warren, John M Maher
  • Processes for the manufacture of methylmercaptopropanal
    Patent number: 6057481
    Abstract: Processes are disclosed for the conversion of propylene to methylmercaptopropanal by converting propylene to acrolein and converting acrolein to methylmercaptopropanal. The processes utilize oxygen and recycle propane to the acrolein reactor. Process feeds can comprise, propane, propylene or mixtures thereof. The presence of propane in the propylene-to-acrolein reaction can enhance the efficiency of the processes.
    Type: Grant

  • High ethylene to ethane processes for oxidative coupling
    Patent number: 5073656
    Abstract: Oxidative coupling of lower alkane to higher hydrocarbon is conducted using catalyst comprising barium and/or strontium component and a metal oxide combustion promoter in the presence of vapor phase halogen component. High ethylene to ethane mole ratios in the product can be obtained over extended operating periods.
