Joseph L. Schmitt, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for the synthesis of an alkyl nitrile from an alkanol
    Patent number: 4731464
    Abstract: Alkanols, e.g., octanol, are reacted in gas mixtures with excess ammonia and preferably hydrogen at temperatures from 180.degree. to 340.degree. C. over supported catalytic oxides of copper, manganese, antimony and tin at atmospheric to moderate pressures. Depending on the selected catalyst and selected temperature, yields of 40% to 98% of monoalkyl amines or nitriles are produced. Other organic substrates, such as aromatic alcohols and aldehydes, aliphatic aldehydes, esters and primary and secondary amines can also be converted to nitriles at yields greater than 90%. The process is readily adaptable for continuous flow processing.
    Type: Grant
    Filed: March 9, 1987
    Date of Patent: March 15, 1988
    Assignee: American Cyanamid Company
    Inventors: Roger J. Card, Joseph L. Schmitt, Jr.

  • Process for preparing N,N-dimethylaminobenzoic acids
    Patent number: 4233458
    Abstract: N,N-Dimethylaminobenzoic acids are prepared by a two-step process of reductively alkylating nitrobenzoic acid in methanol in the presence of a palladium catalyst.
    Type: Grant

    Inventors: John H. Bright, Joseph L. Schmitt, Jr.
  • Oxidation catalyst and use in the production of anthraquinone
    Patent number: 4215063
    Abstract: Anthraquinone is prepared by the oxidation of diphenylmethane compounds in the gas phase in the presence of vanadium (V) oxide and a metal selected from ruthenium, rhenium, cerium, niobium and rhodium, and optionally a third metal selected from manganese, barium, cerium and iron.
