Oxidative dehydrogenation in the presence of chlorine

Claim 1

THE METHOD FOR DEHDROGENATING ORGANIC COMPOUNDS HAVING 2 TO 20 CARBON ATOMS SELECTED FROM THE GROUP CONSISTING OF HYDROCARBONS AND NITRILES TO PRODUCE A DEHYDROGENATED PRODUCT HAVING THE SAME NUMBER OF CARBON ATOMS AND THE SAME STRUCTURE WITH THE EXCEPTION OF THE REMOVED HYDROGEN ATOMS WHICH COMPRISES HEATING IN THE VAPOR PHASE AT A TEMPERATURE OF ABOUT 400*C. THE SAID ORGANIC COMPOUND HAVING A >CH-CH< GROUP WITH OXYGEN IN A MOLAR RATIO OF GREATER THAN ONEFOURTH MOL OF OXYGEN PER MOL OF SAID ORGANIC COMPOUND, CHLORINE IN AN AMOUNT OF LESS THAN 0.3 MOL OF CHLORINE PER MOL OF SAID ORGANIC COMPOUND AND IN AN AMOUNT OF NO GREATER THAN 10 MOL PERCENT OF THE TOTAL GASEOUS MIXTURE IN THE DEHYDROGENATION ZONE, THE RATIO OF THE MOLS OF SAID OXYGEN TO THE MOLS OF SAID CHLORINE BEING AT LEAST 2.0, THE PARTIAL PRESSURE OF SAID ORGANIC COMPOUND BEING EQUIVALENT TO LESS THAN ONE-HALF THE TOTAL PRESSURE IN THE PRESENCE OF A CATALYST COMPRISING AS ITS MAIN ACTIVE CONSTITUENT (1) A COMPOUND SELECTED FROM THE GROUP CONSISTING OF OXIDES, SALTS AND HYDROXIDES OF ALKALI AND ALKALINE EARTH METALS AND MIXTURES THEREOF, AND (2) METALS OR COMPOUNDS THEREOF OF PERIODIC TABLE GROUP VIIIB, THE SAID (1) BEING PRESENT IN AN AMOUNT OF UP TO 50 WEIGHT PERCENT OF THE TOTAL WEIGHT OF THE SAID (1) AND (2) WITH THE WEIGHT PERCENT OF THE CATIONS OF THE DEFINED (1) AND (2) BEING AT LEAST 51 PERCENT OF ANY CATIONS IN THE CATALYST SURFACE EXPOSED TO THE REACTION GASES.

Claim 2

THE METHOD FOR DEHDROGENATING ORGANIC COMPOUNDS HAVING 2 TO 20 CARBON ATOMS SELECTED FROM THE GROUP CONSISTING OF HYDROCARBONS AND NITRILES TO PRODUCE A DEHYDROGENATED PRODUCT HAVING THE SAME NUMBER OF CARBON ATOMS AND THE SAME STRUCTURE WITH THE EXCEPTION OF THE REMOVED HYDROGEN ATOMS WHICH COMPRISES HEATING IN THE VAPOR PHASE AT A TEMPERATURE OF ABOUT 400*C. THE SAID ORGANIC COMPOUND HAVING A >CH-CH< GROUP WITH OXYGEN IN A MOLAR RATIO OF GREATER THAN ONEFOURTH MOL OF OXYGEN PER MOL OF SAID ORGANIC COMPOUND, CHLORINE IN AN AMOUNT OF LESS THAN 0.3 MOL OF CHLORINE PER MOL OF SAID ORGANIC COMPOUND AND IN AN AMOUNT OF NO GREATER THAN 10 MOL PERCENT OF THE TOTAL GASEOUS MIXTURE IN THE DEHYDROGENATION ZONE, THE RATIO OF THE MOLS OF SAID OXYGEN TO THE MOLS OF SAID CHLORINE BEING AT LEAST 2.0, THE PARTIAL PRESSURE OF SAID ORGANIC COMPOUND BEING EQUIVALENT TO LESS THAN ONE-HALF THE TOTAL PRESSURE IN THE PRESENCE OF A CATALYST COMPRISING AS ITS MAIN ACTIVE CONSTITUENT (1) A COMPOUND SELECTED FROM THE GROUP CONSISTING OF OXIDES, SALTS AND HYDROXIDES OF ALKALI AND ALKALINE EARTH METALS AND MIXTURES THEREOF, AND (2) METALS OR COMPOUNDS THEREOF OF PERIODIC TABLE GROUP VIIIB, THE SAID (1) BEING PRESENT IN AN AMOUNT OF UP TO 50 WEIGHT PERCENT OF THE TOTAL WEIGHT OF THE SAID (1) AND (2) WITH THE WEIGHT PERCENT OF THE CATIONS OF THE DEFINED (1) AND (2) BEING AT LEAST 51 PERCENT OF ANY CATIONS IN THE CATALYST SURFACE EXPOSED TO THE REACTION GASES.
