Claim 1

THE PREPARATION OF AN UNSATURATED ORGANIC CHLORIDE COMPOUND WHICH COMPRISES INTRODUCING INTO A REACTION ZONE, IODINE AND AHYDROCARBON OLEFIN SELECTED FROM THE CLASS CONSISTING OF ACYCLIC AND CYCLIC MONOOLEFINS HAVING 2 TO ABOUT 10 CARBONS HAVING A HYDROGEN ATOM ON AT LEAST TWO OF THE CARBONS BEARING THE DOUBLE BOND, AND VICINAL THERETO AND IODINE INTO CONTACT WITH A METAL CHLORIDE SELECTED FROM THE CLASS CONSISTING OF CHLORIDES OF BISMUTH, TIN, LEAD, ZINC, CADMIUM, GROUPIIIA METALS, GROUP VB METALS, GROUP VIB METALS, GROUP VIIB METALS, GROUP VIII METALS AND MIXTURES THEREOF AT A TEMPERATURE BETWEEN ABOUT 80* AND ABOUT 300*C., A PRESSURE BETWEEN ABOUT 1 AND ABOUT 200 ATMOSPHERES AND IN THE PRESENCE OF BETWEEN ABOUT 1 AND ABOUT 20 MOLES OF WATER PER MOLE OF SAID METAL CHLORIDE, RECOVERING FROM SAID REACTION ZONE AN ORGANIC CHLOROIODO COMPOUND, SUBJECTING SAID CHLOROIODO COMPOUND TO PYRLYSIS BY HEATING SAID COMPOUND TO A TEMPERATURE BETWEEN ABOUT 300* AND ABOUT 550* C. T DEHYDROIDINATE SAID COMPOUND, RECOVERING FROM SAID PYROLYSIS SAID UNSATURATED CHLORIDE AND HYDROGEN IODIDE, CONTACTING SAID HYDROGEN IODIDE WITH AN OXYGEN-CONTAINING GAS AT A TEMPERATURE BETWEEN ABOUT AMBIENT AND ABOUT 500*C. TO OXIDIZE SAID HYDROGEN IODIDE TO IODINE AND RECYCLING SAID IODINE TO SAID REACTION ZONE.
