Claim 1
Independent Claim
121 words
A PROCESS FOR PRODUCING BRANCHED MONOOLEFINS BY THE SELECTIVE DEHYDROHALOGENATION OF A MIXTURE OF TERTIARY, SECONDARY, AND PRIMARY HYDROCARBON HALIDES COMPRISING: INTIMATELY CONTACTING SAID MIXTURE WITH A PARTIALLY OXIDIZED PARTICULATE CONVENTIONALLY ACTIVATED CARBONACEOUS MATERIAL PRODUCED BY SUBJECTING A PARTICULATE CARBONACEOUS MATERIAL SELECTED FROM THE GROUP CONSISTING OF CARBON BLACK AND ACTIVATED CARBON TO FREE-OXYGEN CONTAINING GAS IN THE TEMPERATURE RANGE FROM 500-700*C. DURING A PERIOD OF TIME RANGING FROM ABOUT ONE SECOND TO ONE HOUR; HEATING THE RESULTING MIXTURE IN THE TEMPERATURE RANGE OF BETWEEN ABOUT 125 AND 200*C. AND UNDER CONDITIONS OF PRESSURE SO AS TO VOLATILIZE THE RESULTING BRANCHED OLEFINS; AND SEPARATELY RECOVERING THE OLEFINIC COMPOUNDS, LEAVING UNCONVERTED SECONDARY AND PRIMARY HYDROCARBON HALIDES SUITABLE FOR RECYCLING TO FURTHER DEHYDROHALOGENATION.
