A METHOD FOR DEHYDROGENATING AN ORGANIC COMPOUND SELECTED FROM THE GROUP CONSISTING AN ALKANES AND ALKENES CONTAINING 2 TO 5 CARBON ATOMS, CARBOCYCLIC COMPOUNDS CONTAINING 6 TO 1I CARBON ATOMS, ALKYL KETONES, ALIPHATIC ACIDS AND ALEDHYDES CONTAINING 3 TO 6 CARBON ATOMS, CYANOLAKANES CONTAINING 2 TO 6 CABON ATOMS, AND HALOALKANES AND HALOALKENES CONTAINING 2 TO 6 CARBON ATOMS WHICH COMPRISES REACTING SAID ORGANIC COMPOUND IN THE VAPOR PHASE AT A TEMPERATURE OF ABOUT 400* C. TO ABOUT 850*C. WITH OXYGEN IN A MOLAR RATIO OF AT LEAST ABOUT ONE-FOURTH MOL OF OXYGEN PER MOL OF SAID ORGANIC COMPOUND AND AT LEAST ABOUT 0.001 MOL OF AN AMMONIUM HALIDE PER MOL OF SAID ORGANIC COMPOUND, AT A PARTIAL PRESSURE OF SAID ORGANIC COMPOUND EQUIVALENT TO LESS THAN ONE-HALF ATMOSPHERE AT A TOTAL PRESSURE OF ONE ATMOSPHERE.
