  • Patent number: 7345198
    Abstract: The invention concerns the production of acrylic acid from propane in the presence of molecular oxygen. Said method consists in passing a gas mixture comprising propane, molecular oxygen, water vapour and, optionally, an inert gas, on a catalyst of formula (I) MolVaTebNbcSidOx to oxidize propane into acrylic acid, the propane/molecular oxygen mol ratio in the initial gas mixture being not less than 0.5.
    Type: Grant
    Filed: September 9, 2003
    Date of Patent: March 18, 2008
    Assignee: Arkema
    Inventors: Jean-Luc Dubois, Fabienne Desdevises, Stéphanie Serreau, Damien Vitry, Wataru Ueda
  • Patent number: 7332625
    Abstract: The invention concerns a method for producing acrylic acid from propane, which consists in passing a gas mixture including propane, water, vapor, and optionally an inert gas and/or molecular oxygen, on a catalyst of formula (I): Mo1VaSbbNbcSidOx, wherein: a ranges between 0.006 and 1, inclusively; b ranges between 0.006 and 1, inclusively; c ranges between 0.006 and 1, inclusively; d ranges between 0 and 3.5, inclusively; and x is the amount of oxygen bound to the other elements and depends on their state of oxidation, for oxidizing propane into acrylic acid, and which is carried out in the presence of molecular oxygen, the propane/molecular oxygen mol ratio in the initial gas mixture is not less than 0.5.
