Abstract: Dehydrogenation of isobutyronitrile, ethylbenzene or methyl isobutyrate with iodine and oxygen into methacrylonitrile, styrene or methyl methacrylate at 400* to 800*C is carried out in a reaction chamber in which there are arranged, in the direction of flow of the bulk of the reactants introduced through a nozzle, coaxially from inside to outside first a mixing zone and then a circulation tube.

Abstract: In the oxidative dehydrogenation of organic compounds by means of free halogen, it is an advantage to obtain the free halogen as a result of ammonium halide splitting by bringing an aqueous ammonium halide solution into contact with a flame produced by burning hydrogen or combustible organic gases with oxygen or oxygen-containing gases.
