Method of producing acrylonitrile acrylonitrile or Mythakr Ylwnytryl methacrylonitrile isobutane by oxidation of propane or Alayzwbywtan propane Alnshadryt ammoxidatino

摘要

Abstract: a method for the production of propane to acrylonitrile or acrylonitrile Mythakrylwnytryl methacrylonitrile propane or Alayzwbywtan isobutane by using the ammonia oxidation oxide include Tfa For the propane with ammonia gas or propane Alayzwbywtan isobutane ammoxidation, molecular oxygen, in the gas phase molecular oxygen gaseous phase inside the reactor liquid layer containing the material catalyst The oxide basedSilica as holder of the silica composite oxide containing Almwlybdnm (molybdenum (Mo, Tyllrym (tellurium (Te, Fanadym (vanadium (V Wnywbym (niobium (Nb. Where the interaction by adding a stimulant to Llmhfz catalytic compounds containing at least one Altllyrym (tellurium (Te and optionally at least one Almwlybdnm compounds (molybdenum (Mo inside pain The actor.The method of the present invention firmly the catalytic activity of catalyst material at a high level even without the active catalyst, with a new replacement article. So acrylonitrile continue production or Almythakrylwnytryl methacrylonitrile by oxidation Alnshadryt Llbrwban propane or Alayzwbywtan isobutane continuity of output for a long period of time with al. I acrylonitrile or Almythakrylwnytryl methacrylonitrile.
