    Assignee: Halcon Research and Development Corp.
    Inventor: Sargis Khoobiar
  • Process for the preparation of methacrolein
    Patent number: 4230639
    Abstract: A catalyst composition useful for the oxidation of olefins, particularly the oxidation of propylene and isobutylene to produce the corresponding unsaturated aldehydes acrolein and methacrolein, respectively, comprises the combinatin of oxides of molybdenum, cobalt, iron, bismuth, thallium and antimony, and preferably also silicon. When the catalyst is used for the vapor-phase oxidation of the olefins with molecular oxygen, the aldehydes are produced with high selectivity. Alcohol precursors for the olefins can be used as feed instead of the olefins themselves.

  • Catalyst and process for producing unsaturated acids by using same
    Patent number: 4169070
    Abstract: A catalyst composition useful for the oxidation of unsaturated aldehydes, particularly the oxidation of acrolein and methacrolein to produce the corresponding unsaturated acids, acrylic acid and methacrylic acid, respectively, comprises the combination of oxides of molybdenum, copper, boron, phosphorus and antimony, an alkali metal, and optionally vanadium in predetermined relative atomic ratios. When the catalyst is used for the vapor-phase oxidation of the aldehydes with molecular oxygen, the acids are produced with a combination of good conversion and high selectivity with elevated quantities of aldehyde in the feed and at super atmospheric pressures.
