  • Process for the catalytic production of an analogue of methionine
    Publication number: 20240034716
    Abstract: A method for preparing 2-hydroxy-4-methylthiobutyric acid (HMTBA) or 2-hydroxy-4-methylselenobutyric acid (HMSeBA) by catalytic conversion of 2-hydroxy-4-methylthiobutyronitrile or 2-hydroxy-4-methylselenobutyronitrile, respectively, where said conversion is carried out in the presence of water and at least one weak acid and one catalyst comprising at least one of alumina, titanium dioxide and zirconia.

  • Production of nitrile compounds
    Patent number: 8373002
    Abstract: Organic compounds containing at least one site of ethylenic unsaturation are catalytically hydrocyanated and the medium of hydrocyanation is separated into desired linear organic compounds containing at least one nitrile function, e.g., 3-pentenenitrile, and undesired nitrile by-products, e.g., methylglutaronitrile, and the undesired nitrile by-products are hydrodenitrogenated into ammonia and at least one hydrocarbon compound under an absolute hydrogen pressure ranging from 0.1 to 10 MPa at a temperature ranging from 200° to 500° C. and in the presence of a hydrodenitrogenation catalyst.
    Type: Grant

    Date of Patent: February 12, 2013
    Assignees: Rhodia Operations, Centre National de la Recherche Scientifique
    Inventors: Philippe Marion, Amélie Hynaux, Dorothée Laurenti, Christophe Geantet
  • HYDRODENITROGENATION OF HYDROCARBON COMPOUNDS CONTAINING NITRILE OR AMINE FUNCTIONS
    Publication number: 20110112202
    Abstract: Hydrocarbon compounds containing at least one nitrile or amine functional group, e.g., methylglutaronitrile or ortho-toluenediamine, are converted, via hydrodenitrogenation, into ammonia, hydrogen, carbon monoxide and hydrocarbon compounds, notably into hydrocarbon compounds having a low number of carbon atoms, such as methane, or into ammonia.
