  • Process for the recovery of oxazole
    Patent number: 7211674
    Abstract: A process for the recovery of oxazole comprising contacting a mixture comprising oxazole and acetonitrile with an acid to form an acid salt of oxazole; separating acid salt of the oxazole from the mixture; and neutralizing the acid salt of oxazole separated from the mixture to release oxazole.
    Type: Grant

  • Method for stabilization of crude acetonitrile as oxidation or ammoxidation feed
    Patent number: 5250721
    Abstract: A method of producing stabilized crude acetonitrile (i.e. acetonitrile which has been treated to substantially eliminate polymerization of the acetonitrile upon vaporization) which comprises mixing crude acetonitrile, a strong base and aldehyde together, heating to the reflux temperature of the mixture to stabilize the crude acetonitrile and recovering the stabilize acetonitrile. This stabilized acetonitrile is utilized to manufacture hydrogen cyanide.

    Assignee: The Standard Oil Company
    Inventors: Mark C. Cesa, Mark R. Bruce
  • HCN by catalytic ammoxidation of crude acetonitrile
    Patent number: 5204079
    Abstract: A process of producing hydrogen cyanide from crude acetonitrile comprising contacting the crude acetonitrile with an ammoxidation catalyst at an elevated temperature in the presence of an oxygen containing gas and ammonia. Preferably, the process is performed in the absence of propylene.

  • Photocorrosion resistant semiconductor photoelectrodes
    Patent number: 4574039
    Abstract: A semiconductor photoelectrode resistant to photocorrosion and a method of preparing such a photoelectrode are disclosed. The photoelectrode includes a doped oxide layer on which illumination falls for photo-stimulation. The oxide layer is doped with metallic ions, such as tantalum ions, to suppress photocorrosion. In one oxide doping method, tantalum pentachloride vapor generated by sublimation is directed against a silicon dioxide layer on a heated photoelectrode.
